Infiray C210 Thermal Camera review

[littleboot]

Hi All,

Yesterday I received my C210 thermal camera and I'm very happy with my purchase so I would like to share my findings.
I just got my C210 and have played with it for 2 days, so this is not an extensive review.

In short I bought a Thermal camera from China and it's very good given the price:
Temperature range: -20~550C
Infrared pixels: 256x192 (Nice )
USB video feature
16GB SD card included
And more just read the aliexpress page.

I payed €245,87 (including shipping to The Netherlands)
I had to pay import tax but I was lucky).
I was lucky because the taxable value of this "INFRARED THERMAL IMAGER" was determined to be €17,32.
Vat 21% of this was just €3,64, in addition I had to pay administrative charges of  €4,00. So the additional cost were €7,64
Total: €245,87 + €7,64 = €253,51

I Bought it from Aliexpress:
C210 Infiray Thermal camera.
https://www.aliexpress.com/item/1005001599665046.html?spm=a2g0s.9042311.0.0.27424c4d5bxi8W
€253,51

Update: it looks like the UNI-T aliexpress store does not sell the C210 anymore but C200 (I'm not sure if they are the same now, as far as I know the only difference is that the C210 supports USB video recording)

In addition I bought a lens for better closeup picture. (I did not think of this myself, but read somewhere on this forum someone used this lens type, thank you unknown guy!)

CO2 ZnSe Focus Lens Dia.20mm FL350.8
https://www.aliexpress.com/item/32241074105.html?spm=a2g0s.9042311.0.0.27424c4dbHaBMz
€ 8,26

In addition I bought (NOTE do not buy this):
"Cloudray C Series CO2 Lens Tube Outer Diameter 24mm for Lens Dia.20mm FL50.8/63.5/101.6MM for CO2 Laser Cutting Machine " (€ 8,41 X1)
"Cloudray Lens Mirror Removal and Insertion Tool for C&E Series Lens Tube Nut-removal" (€ 6,30 X1)
My thinking was I would use these to fix the lens to the thermal camera someway, I went with a more high tech solution of black electrical tape instead, I might 3D print something better in the future.

I have attached some photo's to this post, so you can get an impression of the results.

You have to ask the supplier for the PC software tool, it is not available for download on the infiray official website I asked them why it is not on the website and they told me it is because of bandwidth constraints. (wierd but oke, I will share it here).
I have received the software from infiray and the uni-T aliexpress store, one is an installer the other is portable version. Currently the version I poses is V1.1.4 (Please if you have a newer version share it)
The software and some thermal images and one thermal video (so you can try out the software yourself) can be found on my file server:
https://tomklijn.stackstorage.nl/s/YqG0kCyvNlqUDk3K
To select the folder containing the thermal images you have to click on the text "Preview" in the left side of the window.

Note, Most of the closeup PCB pictures are taken through the ZnSe lens, (you can verify by enabling fusion mode in the software, if the thermal and photo images are not aligned I have taken the image through the ZnSe lens).

The only things I do not like about this camera (so far):
-sometimes the tigger button to capture an image is not detected. (seems to work after the first image has been taken, some kind of software bug).
-no firmware updates

I would love to disassemble this camera to check out what makes it tick, however it is quite expensive and I do not see how to get inside without breaking it. (I would like to know how to replace the battery in the future). Maybe a new video idea for Dave 

[Berni]

Now that is a pretty sweet price for what is seemingly a perfectly good "high resolution" thermal camera.

How good is the noise on the image when measuring things that only slightly warm? Like trying the old trick of leaving a warm hand print on a table.

[littleboot]

For my it's a new trick . I just tested it. (the thermal images are also added to shared file drive for PC analysis).
Seems oke to me but I know next to nothing about thermal camera's (This will change  ).
Please let me know what you think.

[Berni]

That looks nice and clean to me. By the way does it support exporting any lossless image formats like PNG or BMP?

I am not much of a thermal camera expert myself, mostly use a ThermalExpert Q1 at work. The images looks pretty similar to that (apart from the Q1 having double as many pixels). But i am sure the usual eevblog resident experts on thermal cameras will swing by here anytime for some more in depth comments.

[littleboot]

Thanks for your feedback. I have not found any setting to change the format of what is saved on the SD-card (jpg and irg by default), I'm pretty sure it can not be changed.
However when I connect the camera to my PC in usb camera mode and take a capture it is stored as bmp inside "IRPT_TAS_V114\CaptureBmp\20210801" folder (I have attached the bmp to this post).
 

[Ultrapurple]

This sample image you posted is very very good for a budget-price camera. Remarkably good clarity and, particularly, depth of focus.



The ZnSe lens was an excellent investment and is clearly working well. A word of caution - the lens material is very soft and easily scratched so it's worth keeping in a protective cover when nor in use, rather than having it skidding around the bench like you can get away with for a glass lens. Also, clean it with care.

[Fraser]

Infiray (IRay) are producing some really excellent thermal imaging cores and cameras. They also offer the higher frame rate which is a bonus. FLIR and Seek Thermal have some serious competition in the marketplace from the latest Chinese imaging cores 

[Ultrapurple]

And it's amusing to think that it's probably a serious Federal offense for a US Citizen to buy (perfectly legally) but then export an IRay thermal camera...

[ArsenioDev]

Not if it's to a STA country and you report export to DDTC! No license required at all, just a signed end user agreement and a report of export.
I've spent the last month or so getting that all clarified and verified with the agencies, it's pretty simple.

[andrewusher]

Does it save the radioemetrics to the jpg?

Cheers,

Andy

[edubz]

can you take it out side and see how it looks?


I had a monocular and it use to make me blind in one eye after using it.

Im just wondering how trees and other animals would look in that thing

I was thinking of getting one of these as a toy for a young boy, its something different and I dont want them to damage their eyes using a monocular so I am looking at hand helds

does it have zoom? Can it focus?

[Ultrapurple]

<whinge>
Playing Devil's advocate, I can't help thinking that if it takes a clever person a month (=$$$) to navigate the system then that's a pretty strong disincentive for other people to even try. Hence perhaps why Infiray et al are about to clean up in the 'Rest of the World' market.
</whinge>
Having ramped up supply for Covid (irrespective of whether the resulting products are any use), I suspect (or hope) there will soon be a relative glut of sensors, resulting in a wide range of keenly-priced thermal toys. For instance, I can imagine thermal becoming a standard fitting on upmarket but affordable drones. Having just bought one myself with 3-axis stabilised camera, downward-looking position-hold camera and funky, swivelling, laser-shooting obstacle avoidance camera and paid about the same as two fuel fill-ups of the car, adding a cheap thermal sensor seems a likely next move.

[BrotherEstapol]

Great write up! How is the focus without the extra lens?
I'm curious at what distance it loses focus! (though you have proven that just buying another lens solves that anyway)

I'm tossing up between this and the InfiRay TL2; I'm after something to check thermal leaks/spots that need insulating in my house, and also checking the heat bed on my 3d printer. The TL2 has the manual focus, but the C210 seems to have better all round features. (I'm not wedded to having it attached to my smartphone)

This really seems like it might fit the bill, especially at that price!

(the month was mostly low intensity searching while I was primarily focused on silicon shortage sh*tshow with design work)
Actually the real work took me all of an afternoon WFH lunch break while eating sandwiches, Called up the State Dept, they bounced me to DDTC, then to BIS and got all the answers I needed in one call in addition to the reporting specifics, process etc. Didn't even have to do my fall back plan of hopping on the metro into the city and knocking on their door to get answers in person 
Specifically they told me to reference § 743.3 THERMAL IMAGING CAMERA REPORTING of this BIS doc https://bis.doc.gov/index.php/documents/regulations-docs/2256-part-743-special-reporting-requirements-2/file for STA-group 1 countries(really the only ones you want to deal with, they're low headache and don't need anything but a really trivial bit of paperwork (NO LICENSES!), which most of the stuff you'd already have for shipping the unit.

[IwuzBornanerd]

I seem to be missing something here...  That linked document is nothing but instructions for how to make BIS happy AFTER you ship something.  I searched the document for the word "ship" and "carrier" & neither turned up anything about how to get DHL, FedX, or any of the others to actually accept the thing, get it past Customs & take it to the "STA country".  Where is the documentation that spells out the content & form of that "signed end user agreement" & explains how the carrier & customs will accept just that as sufficient paperwork?  No AES account needed to file an EEI like @Dark Volter had to get??  OR are you talking about how simple it is for someone who already has an EIN & an AES account? 

https://www.eevblog.com/forum/thermal-imaging/$300-reward-therm-app-simple-(i-assume)-repair/msg3504528/#msg3504528

I notice that the last thing on his list of actions is that report to BIS.

[tigerbengal2009]

Hi, thank you for posting this, I have been looking around for a thermal camera, this one in particular was of my interest as well, I have been searching and searching in Aliexpress and youtube for more information about this camera, you said is the C210 but in  your link it goes to a C200? it is the same camera? I am still debating between this one and the Seek thermal compactPro.
InfiRay seems to have some impressive phone adapters camera as well, but the lack of reviews and info and no iphone connection, made me not consider them. some adapters are close to $1000!
I need it for motherboard electronic repairs, how do you attach the macro lens that you put the link in your review? the 20mm fl 50.8?

[tigerbengal2009]

sorry I saw it  in the pictures gallery, you are using electric tape, try instead gaffer tape, does not leave residue. if you are good with 3d printers design, I am not, maybe you can do something similar to this

I am still debating between this one and the Seek thermal compactPro.

I was in the same boat, but after seeing this thread I ordered a C210, and it arrived on Friday.(only 10 days from China to Australia)
Aside from the battery issues I posted about in a another thread, I really like the images this camera is putting out!

It has a regular camera built in, and has a few mixed modes, but I haven't had to use them, as the thermal image clear enough that I know what I'm looking at!

I think that the C210 is a new model, and Infiray have not updated their website yet which is why you can only really find it for sale on Aliexpress, and that's it.
Quite frustrating, as all the documentation that came with the device is in Mandarin, and there's supporting documents or software on their English website.

The link you posted doesn't work sorry! Can you try again please?

I also got the lens littleboot suggested(though hasn't arrived yet) and I have a 3d printer, so I intend to design and print a lens holder like you're suggesting! (not keen on using tape!!)

[BrotherEstapol]

Also, I contacted Infiray about the software(forgot about the link in this post!) and the English manual. They send me this link, which looks to be a slightly newer version of the software:(v115)
http://yunpan.raytrontek.com/l/dFlBRO

...and the attached PDF manual.

[tigerbengal2009]

Thank you BrotherStapol for your input and  the software link,  the pdf manual, this is very helpful to take a look at the functions of this camera, reading your comments  , more and more I am thinking to hit the bullet and buy the camera , sorry , didn't realize the link was bad, that is the one that only the lens gave me, but here is another one, this is for the camera Hikvision H10, there you can buy only the camera or the camera plus the macro lens, if you go down a little bit, after AM INSTRUMENT STORE. You can click to see only the lens and the mount it is $59
https://www.aliexpress.com/item/1005001422640955.html?spm=a2g0s.8937460.0.0.5c732e0esBln8y
The shape and holes are for the h10, maybe you can design one for the c210?.
decisions, decisions.....c210 looks good and $135 cheaper than the seek compact Pro
Does the c210 allows you to see a short on let's say laptop motherboard ? 25 hz and the resolution is enough to see a short creating heat in real time?

[BrotherEstapol]

Do you mean this item?
https://www.aliexpress.com/item/1005002656448420.html

I'm not sure if that sort of design could work with the c210, but I'll figure something out! There's always a fix!

Does the c210 allows you to see a short on let's say laptop motherboard ? 25 hz and the resolution is enough to see a short creating heat in real time?

I am not sure, I haven't had a chance to look at any circuit boards with this yet unfortunately! I think if you're buying it to check for shorts, you probably would want a macro lens.

[jairbj]

Hi @littleboot, thank you for the review.

I bought one and it has arrived 3 days ago. It's my first thermal camera.

To my surprise, it is a heavy bulky device. I wasn't expecting it. 

Until now the only thing I miss is the ability for recording videos direct on camera.

Also, I bought the macro lens (it hasn't arrived yet).

Attached a picture for size comparison between a Fluke 62Max Infrared Thermometer and the Infiray C210

My macro lens has arrived.

[jazzyjayzee]

Hello! Also just recently got the C210 and it is pretty impressive. Had an odd startup that only indicated 0 degrees, though the thermal image was intact. Only happened once.

Question - seller provided the PC analysis software but is there a trick to configuring this to run on Win 10? I tried a couple times on different machines, seems to install some run-time bits, installer seems to behave, but running the program gives me an instant alert in Chinese that Google translate tells me is "not supported" and will not proceed.

Thank you in advance! great thread!

Hey, I have checked and I See they have changed it to C200 instead of C210. (I believe the C200 does not have USB video recording feature but is the same otherwise).
I'm not sure, maybe the C200 and C210 are the same now. looking at some other aliexpress listings I read "Please note ：C210 is a new upgraded model of C200" but they are listed as the same.

I have attached a screen shot of my order to this post

Yes it should be possible to use it to find a short in real time, especially with an addition lens like I have used. (you can see the real time performance when watching the video of the thermal camera on my filedrive)

Arrghhhh   
This forum did it again

I had to .... Your fault ....

One C210 + "Lens" on the way from Ali.

If noone from Denmark is available, can try to do so. Would print it in PLA and TPU, as suggested in Thingiverse. Stock material: PLA could be black, white or grey, TPU is transparent. I have no possibility to test it as I don't have a C200 (yet). PM me if you are interested.

So turns out that URL is now dead,(thanks to SamHeat for telling me!) so I've uploaded what I have to a shared folder on my google drive:

https://drive.google.com/drive/folders/12WsdT_dUAeV2kSs8V12o6eUM0w5Voa8v?usp=sharing

You should be able to see 2 versions of the software installer and a manual in the subfolder, as well as a PDF for the camera itself in the root directory.

Hope this helps someone!

[bostwickenator]

These images are looking amazing especially at the price point. I've just put in an order for an Infiray camera based on the same core. I think it's fair to say Infiray has put some serious competition to the US companies. This isn't surprising given their much larger market potential and lack of regulation. With suppliers like this in the market I wonder if US companies (eg Seek) will lobby for changes to US export regs.

[Hydron]

Thanks for the info, hopefully these become available on platforms other than aliexpress - it's fine for personal purchases but is a harder sell for work (price is probably good enough to convince them to get one for general use, without an urgent need).

[litchiate]

I made a slidable lens holder for it.

ZeSe lense, Diameter: 12mm, Focal Length: 50.8mm.

Great post!

I’m looking at one of these myself and wondered if you could answer a question for me…is it possible to get plain images out of this, without all the information? Thinking for creating panoramic photos.

Thanks,

[illiac4]

Hi.

You have not included the lens holder just the base.

TNX

[Bill W]

spec >> https://www.infiray.com/P2.html
Focal Length 3.2mm
F1.1
FOV 56x42

InfiRay techsup told me that the shining metal cover is the germanium lens.

The P2 Mini has a long focal length and requires a macro lens for close-up works. 

I also wonder how to choose a macro lens for it, particular a right focal length. 



Calculating Camera Sensor Resolution and Lens Focal Length


Lens Focal Length

Due to the large germanium lens, I wonder what size the sensor actually is. 

You are making, and being given, some false assumptions that are not helping your understanding.

1 - The lens is not the shiny flat metal circle.  That will be a cover / weather seal.
The lens must be about 3 mm diameter, due to focal length and f number given.  It will also not be flat on the front, I'd expect something like the FLIR-One picture you show.

2 - With a 3.2mm fl lens and a 56 deg horizontal field of view the sensor active area would be 3.2mm x 2.4mm.  That, within rounding, matches the published specification (256 x 192 pixels with 12µm pixels = 3.1 x 2.3 mm).

3 - The P2 mini has a *short* focal length, and so a wide field of view.  What you have observed is that it is focussed at infinity (or at least a few metres), hence a problem viewing up close.

[Fraser]

Redbook,

If you were to dismantle your P2 I would expect you to find the Infiray Tiny1 core behind the lens protection window.

Look here for details of the core. The P2 has a close focus capability of around 10cm minimum. The T2L uses the larger S0 core that offers manual focus. For me, I would choose the T2L for PCB work, but the P2 is also very capable and offers a 25 frames per second refresh rate

Hi,

I just received my P2 Mini camera, and it is fantastic. 



spec >> https://www.infiray.com/P2.html
Focal Length 3.2mm
F1.1
FOV 56x42

InfiRay techsup told me that the shining metal cover is the germanium lens.

The P2 Mini has a long focal length and requires a macro lens for close-up works. 

I also wonder how to choose a macro lens for it, particular a right focal length. 



Calculating Camera Sensor Resolution and Lens Focal Length


Lens Focal Length

Due to the large germanium lens, I wonder what size the sensor actually is. 

Is it similar to the Lepton module ?  SystemPlus Publishes FLIR Lepton Reverse Engineering



I came across the following DIY macro lens.  It looks very good but there is no information about the lens.

Thank you,

[redbook]

Thank you very much, Fraser & Bill.   

Oh.  It's a version of the Tiny T1 module.  This was what I suspected initially. 

I wonder why the P2 designer put a large germanium window in front of the module.  Could it be smaller ?

If the Tiny T1 module has a lens of 3-4mm diameter, then a macro lens of 10mm in size would be enough ?

I came across a DIY macro lens for the HTI-20, photos attached.

That lens mount looks to be an adapted mobile phone supplemental lens mount. The ZnSe lens has been mounted in the area where a lens is normally screwed in. I have bought many such mobile phone lens sets t the clip spring appears very strong so I am nervous of using such on anything that could not stand the pressure. Mu concern with the P2 would be whether squeezing it would gamage the front window. Regarding that front window, it is unlikely to be Germanium. More likely Chalcogenide IR glass or even thin silicon with appropriate AR coating. I do not know how thick it is and how much pressure it would tolerate before fracturing. The large window area could be due to the wife field of view vs position of the imaging core lens behind the window or it could be purely aesthetic for marketing purposes to give the appearance of a much merger ‘lens’ than competitors.

I detailed clip on supplemental lens mounts in my UTi80P thread and will add a link below. An adaption of the ‘microscope stand’ holder fir the P2 would be the way I would go for a lens holder.

In case it is of interest, I found a 3D printable tripod mount for the P2. Useful for mounting on a gooseneck desk mount like the one I used on the UTi80P/Multicomp camera

Getting us back on the C210 track....

The latest software link that was posted, v1.16.  My Chinese is very limited    I ended up with a download named "DeliveryTool". Is that correct?

Thanks.

[wavepax]

Yesterday I installed the Infiray Thermographic Analysis Software on a Windows 7 x64 PC and a Windows 10 PC.   For Windows 7, I received an error message.   I sent the below email yesterday and received a reply today that fixed the error.   Attached is a dll file needed to fix the error.   No error when installing on a Windows 10 PC, but the interface comes up in Mandarin.   Clicking the globalT icon at the top gives the option to switch to English.

By the way, seeing the spirit of others helping each other in this thread inspired me to register and post here to inform and help others.   This is my ZeroPoster electrical engineer Internet good deed for the day.

Before seeing this thread, I ordered a C200 along with 10cm focal length lens from the same place that you all linked to in this thread.   That focal length, along with the field of view of the C200, is good enough to put all the pixels on a 10cm x 10cm circuit all at once into focus.   

I've been waiting decades for an affordable thermal camera with good enough microbolimeter array resolution -- spatially (256×192 pixels), temperature (0.1C) and time (25 Hz frame rate) wise along with a dynamic temperature range of -20C to 550C (over two different gain settings).   THE NETD (noise equivalent temperature difference) is < 40mK.   Shipped to my door in the US, it was USD$298.    The C200 Pro has the same specs except better temperature resolution (0.04C) and timed photography.   I didn't see the C200 Pro price anywhere on Dec 15, 2021.   Perhaps it is sold on taubau, which pretty much restricts sales to China-phoned people, and the website is in Mandarin, requiring a Google translation.   

The next step up in spatial resolution, the M300, was priced at USD$3200 on Dec 15, 2021 and has 384x288 thermal pixels, variable focus to 10cm, slightly larger screen, but the same temperature resolution as the C200 (0.1C).  The T3S, a smartphone addon thermal camera, has 384x288 thermal pixel resolution and costs USD$800 + tax.

In addition to detecting shorts and failed components on a PCB (printed circuit board), the C200 is useful to detect gas leaks, like in the exhaust gas piping in a vehicle.   The C200 is good enough to see if insulation was installed correctly in the walls of houses and buildings.   Pointing the C200 at the ceilings and walls of my house shows the lower ceiling temperatures at the framing compared to the insulation between the framing.   Youtube has videos of the C200 being used to detect people and animals at night.   Latent hand print heat is easily detected as long as you have enough pixels to resolve at the viewing distance.

Be careful about some of the rebranded models on ebay.   Some look like the above C200, but actually are a C200K which restricts the temperature range to human skin surface temperature ranges and is designed to detect elevated temperature from an infection.

I am amazed that uncooled microbolimeter arrays can have such good temperature resolution.   Perhaps Dave can look into the physics and engineering and create a video explaining how these uncooled microbolimeter arrays achieve such low temperature resolution at low noise.   I'm guessing that they integrate in time to help lower the thermal noise.

Temperature resolution and NETD are not the same.  A still frame can have quite high noise - ie standard deviation of data maybe 400mK.
Spot temperature readouts will certainly be averaged over at least 1 second - 25 frames - more likely 32 or 64 for computing simplicity.

Essentially each pixel is a thermistor hanging in a vacuum on thin legs.  The material might be silicon (A-Si) or Vanadium oxide (VOx).
VOx has a better response (resistance change per temperature change) but was less favoured for processing reasons so A-Si is still going with some suppliers.  All things being equal a VOx should be a better image, but the gains are usually spent on cheapening other parts like lenses or the detector pixel size.

When you focus a thermal scene on the pixels they change temperature very slightly, and so change resistance.
Each one is in turn connected to an R-C integrator opamp for one TV line, fed from a bias voltage and the resultant voltage that accumulates is read out, typically by a 14 bit ADC.

The difficulties are that the 'thermistors' are far from identical, nor are the R-C integrator op-amps, so there is a lot of fixed pattern with relatively little scene (more scene in a VOx than an A-Si).
That is where calibrations and some frame-level maths comes in.
Noise mainly comes from the sensor bias(es), the ADC biases, and the ADC quantisation.  There may also be some worse quantisation later on in the image maths, and in the display side.  However once displayed at video rates you have the human eye-brain averager working for you.

Thinking of ordering one of these off Aliexpress for general use. Anyone know why UNI-T is selling a competitor's product through their store at a huge discount to the "official" price?

My macro lens has arrived.

Lens: https://www.aliexpress.com/item/32241074105.html
Diameter: 20mm
Focal Length: 50.8mm

I attached some images.

Also posted the build of my lens holder here:
https://www.thingiverse.com/make:968854

Thank you for creating the lens holder!, I will 3D print one for myself. Very nice design using the rubber bands

Just to correct  some possible misunderstanding : jairbj did not create the model. He just printed it  and posted his print. He properly refers to the original
model https://www.thingiverse.com/thing:4901923 . It happens that I am the proud creator of this masterpiece, including the rubber bands holders  

[Andrew LB]

Infiray (IRay) are producing some really excellent thermal imaging cores and cameras. They also offer the higher frame rate which is a bonus. FLIR and Seek Thermal have some serious competition in the marketplace from the latest Chinese imaging cores 

Well Joe Biden did give them plenty of Eotech GPNVG-18 ($42,000) night vision goggles as well as many lesser high tech PVS-14's free of charge in Afghanistan, so they've got plenty of stuff to reverse engineer.

[flatterband]

I made a slidable lens holder for it.

ZeSe lense, Diameter: 12mm, Focal Length: 50.8mm.

refer
https://www.thingiverse.com/thing:5137854

Excellent Idea - thanks a bunch 

It found no slide.STL for the lens holder on the thingiverse link so i used a solidworks Viewer to load slide.SLDPRT and export this to slide.STL. Solidworks used micrometer instead of milimeter, so this slide.STL has to be scaled 1000x to fit.

I have attached the "missing" slide.STL - hope it helps anyone who wants to print your slideable lens.

[JM1010]

Just received my c200 and macro lens. What are the recommended settings for pcb work? Emmissivity etc. Manual says .91 but I’m not sure. Also distance seem to be in meters. Any possibility to adjust lower to reflect pcb small distance? Thanks in advance.

[matej_cro]

Go to facebook and join to INFRARED TERMOGRAPHY group. then search for work "C210" and you will see many post from my colegue Mark Berger that have that Infiray camera and use it for PCB repairs in his company. So you will find a lot of settings, image samples etc... Just contact him and thats it.

[Creep]

Looking into purchasing a thermal camera for electronics design/repair and the infiray C210 seems to fit the bill pretty well (coupled with the macro lens, that is).
The trouble is that the C210 doesn't seem to exist/be sold anymore. Spotted some mentions of the C200 Pro as well, but that is also pretty much nowhere to be found.

Live temperature data streaming to a PC would be a really usefull feature for me and not something I would want to miss out on.
There seems to be some very conflicting information available on the web so just wondering whether someone knows: have infiray given the C200 the UVC support or is such a camera simply no longer available?

[matej_cro]

I have email for distributer from Poland. He have C200 and C200 PRO on stock. C200 = 499$, C200 PRO = 569$.
contact mr. Prezemyslaw Degorski on mail: p.degorski@aiq-robotics.com if you want to buy one from EU stock. 

[Creep]

I've already placed the order for a UTi260B, but thank you for the offer.

As a sidenote, for anyone wondering, the aliexpress Uni-T store answered that the C200 doesn't offer USB video capabilities.

Great review with a very unbiased opinion backed with some first-hand experience with the handheld thermal camera. They seem great value for money especially when the vision you showed was so clear, an awesome review thanks so much.

[optotester]

Hi all, for anyone interested here is last firmware version 1.3.8 from 27 Feb 2022.
It is targeted at C2XX series in theory (mine in C200) - please be extremely careful, I am not sure at all it will work on C210, although I do not think there is any hardware difference with C200.

Note that it seems possible to execute files at boot, so the camera can be most likely modified. The UVC functionality seems to be defined by a variable in the S90start file.

EDIT: Attachment removed - it is for C200 based on HiSi3516 platform, different for the C200/C210 from early batches which are IMX6 based.

[bebopdk]

Have you installed this firmware on your C200? would like to try it on mine, but it would be nice to hear how it works 

[keenox]

Any luck extracting/installing firmware on the C200? I had to decide between A-BF RX-680 (found afterwards that is is the Infiray C200) and the Uni-T UTi260. I asked the seller and said both have PC live video and that the C200 has better battery. I trusted them only to find out it doesn't have live PC video 
I read the Infiray manual and my guess is that only the software is different

[optotester]

No success so far, it says it does not find the file maybe I need a smaller SD card.

The upgrade procedure in the Word is wrong, to activate update mode the command is to push right 1 second then left on the main screen. This activate the update popup.

Creating an upgrade folder at the root of the SD Card takes a backup of the calibration settings in a file.

Also pushing up then down (or down then up) triggers the advanced settings menu, allowing to recalibrate the device with two points 10ºC and 120ºC.

[labeanchik]

Real-time temperature reading support via USB only for C200 Pro model.

Someone used Hikmicro B20 - how much more profitable to buy this model?
She already has support for broadcasting information in real time via Wi-fi.
But the cost is much more.

[optotester]

For info, I explained here https://www.eevblog.com/forum/thermal-imaging/uni-t-uti260b/msg4361233/#msg4361233 how to take a backup of the current firmware of your device.
Only difference is for teardown, there are 6 screws behind the screen on the C2xx series (under the adhesive).

If anyone is willing to share its firmware it would be great (even if backup takes 4GB, compressed is only few dozens of MB).

[optotester]

DISCLAIMER - I am not responsible if your device get bricked. I minimized the changes performed on the system but we still need one file to trigger the update. I use uti160e which seems to be a test trigger, not used in any commercial device.


Hello, I highly simplified the firmware backup process presented previously. I hope it will help people to provide a copy of their current firmware. The U-Boot way of taking a backup does not alter any data on the camera so it is preferred, but having a "one-click" backup method, which do NOT require to teardown the device can be useful too .

This method replace the file used for USB Disk mode to provide root access to the camera. It activates a serial console through USB, along with mass storage (you need to have an SD in your device !).

It will make possible the activation of UVC for any camera, even if not supported by default - but I need to collect firmware for that first.

1-Format SD Card using MBR FAT32 (important - do not use GPT)
2-Create a folder called "Upgrade" at the root of the card
2-Create a folder called "Backup" at the root of the card
3-Copy the 2 files provided in the Upgrade folder
4-Initiate the upgrade procedure by pushing the right button for ~1s, releasing it and at the same time quickly pressing the left button
5-Select "APP"
6-Reboot

If you have an SD Card in your camera, it will be recognised as a CDC ACM device (acting as Mass Storage and Serial Port at the same time) when USB Disk mode is selected.

Typical serial port is /dev/ttyACM0 (Linux) or /dev/usbmodemXXXX (OSX).
Parameters are 115200/8-N-1.

2 Users are available:
Root access : root/password
Normal user access : ftpadmin/ftpadmin

To take a quick backup of your system, create a folder called Backup at the root of the SD Card, reboot and switch from USB Camera mode to USB Disk. It takes ~30s max (there is no visual feedback except for a "Done" line written on the serial console).

To take a full backup of your system, create a folder called FullBackup at the root of the SD Card, reboot and switch from USB Camera mode to USB Disk. Wait for ~15 min without performing any action (there is no visual feedback except for a "Done" line written on the serial console).
Backup is 3.7GB but <100MB compressed.

If for any reason the root password is not "password", create a folder called "ForceRoot" to force the password to be changed.

As an example, I attach C200 firmware 1.1.1.0 (which has UVC working on Linux/OSX but not with default Windows drivers):
https://www.mediafire.com/file/d8svb1cvmt5g43m/Original+FW.zip/file
Please do not use that firmware, you most likely have a more recent firmware. I think I have one of the oldest batch.

[bebopdk]

 :-+Wow! Great work!
Looking forward to try this out when I have time.

[keenox]

@optotester I tried it but I get the same message "Found application failed! Please check again!" and it only puts CalTempConfig.ini in the Upgrade folder
Nevermind, I didn't read the part where I needed to put the files in the Upgrade folder. I put them in the root.
The script seems to execute as the serial appears in Device Manager, but the backup is not written. Can't seem to be able to connect to the serial device (using Win10). Tried both PuTTY and Realterm
Currently fiddling with the script.

BTW, why don't you get the path to the SD card from the script path (I'm guessing it is executed directly from the card and it is not copied) and iterate through mounts instead?

Update: Also tried connecting to serial using WSL and a Debian VM. Still no luck. Terminal is silent. No keypress echo and no output.

[optotester]

Script is only executed when switching to USB Disk mode using the app. It is not executed from the SD.
Basically file is copied to the device and replace the script used when selecting the USB Disk mode. Most likely this file does not have the same name with your firmware version, hence it is not loaded when selecting USB Disk mode.

I could put the script in apps.sh instead but if the iray app has a different name that my camera it will basically stop it from running - and the app is used to manage firmware upgrade - so the risk of bricking the device would be too important, which is why I did not take the risk. Plus, by overwriting apps.ah we won’t be to take a backup of it. I will try to add a small qt app with a message box to confirm if script is running or not.

Camera have serial exposed by default so it does not mean that script was executed. By default, no terminal is running on it. To progress further you would need a backup taken from UBoot to look at the file structure (best) or at least a listing of files in /etc/rc.d by connecting with the LVTTL header (easier) with ftpadmin/ftpadmin user (which exists by default).

[keenox]

On C200 (which I have) there is no switching to disk mode. It is always in disk mode.
Also, I tried renaming the script to apps.sh and it behaves the same (nothing). Also tried a little script which should create a new file in the same directory and also didn't seem to work (tried both your name and apps.sh). Didn't know it copies the apps.sh from the Upgrade folder, but it seems it didn't on my end, because it would have been bricked already (thanks for letting me know btw).

I could take mine apart, but don't see any screws beside the ones that hold the USB port and MicroSD slot. I think I might be able to take a backup of the flash if it is discrete or connect via JTAG (I think I have a small JTAG adapter, but never used it).

[optotester]

There are 6 screws behind the screen + 4 behind rubber (shown in the video from UTi260b teardown above). Different type of C200 seem to exists - maybe yours is HiSilicon based ? A teardown would confirm that

[keenox]

Seems pretty daunting if you want to put it back again. Did you manage to put yours back together the same way it was before? I have an UTi260B on the way and wouldn't sacrifice this one until that one arrives safe and sound
Btw, mine is called A-BF RX-680, but the seller confirmed it is the same with C200

[bebopdk]

On my C200, the serial port shows up in the device manager without using this hack, but I am not able to connect to it with anything, just as you write, so perhaps the script is not executed and you just see a serial port like I do? I have attached a picture of the ID's of the C200 serial port which shows up when I connect the C200 USB to my PC.

Do we know how many FW versions there are?, my C200 is: V.1.1.10

[keenox]

Same hw id of the serial port. My firmware is 1.1.18

[Krist-win]

windows data analysis is perfect.

[optotester]

For info, last firmware version for C200 is 1.1.18.

1.1.10 is the version I had - the upgrade process only copy some hardcoded files to hardcoded paths based on the presence of "uti160e" or "IRay_C200_Thermal" files in the Upgrade folder. IRay_C200_Thermal being the app itself you won't be able to re-initiate an upgrade if you mess up with that file.
 
1.1.18 is the last one received by IRay - for info, it runs the file Upgrade/upgrade.sh when update is triggered (only if "uti160e" or "IRay_C200_Thermal" is present). The upgrade.sh file is in charge of copying the files (no more hardcoded files).

[bebopdk]

Could you please share the C200 upgrade to 1.1.18 SD card image?

[dl6lr]

I would have backed up my C200, however it does not switch on the getty with the usbdisksettings.sh upgrade nor does it backup files to the SD. It seems to do no harm either, I assume it gets never called. My unit is on version 1.1.10 too. There is no switching of USB between disk and other mode, but the executable refers to usbdisksetting.sh for the upgrade process and both /etc/rc.d/usbdisksetting.sh and /etc/rc.d/usbcamerasetting.sh. It includes the menu texts for USB disk and camera, but this is deactive in my unit. I think this is a pro enabled feature.

I noticed some flaws in their implementation:
1. It provides the disk access through USB as a static image, any pictures taken after you connected with the PC are not reflected to the PC.
2. If you unpower with USB connected, it takes very long until the USB disappears. And then you cannot switch the C200 on again. You first have to unplug the USB.

[keenox]

@optotester: Did you manage to make it run? Does it still copy the script to the internal flash and then executes? Does it get executed instantly or upon reboot?
I created a custom named file on the SD and then used find in the upgrade.sh script to find it and create a file in the same directory, but doesn't seem to get executed.

[keenox]

The UTi260B arrived today so I manned up and opened the C200/RX-680
It has an NXP MCIMX6Y2CVM08AB
I only managed to login with ftpadmin, but that can't write to the SD card. I will try to do a backup through serial alone.

Looks good.
which is better c210 or uti260b? Is that true both of the model has 25hz frame rate?

[keenox]

Just cracked the root password (left the PC overnight). It is "uti160e". Never thought to try it 

@thermalengineer: I did not open the 260, but from what I understand so far they have the same harware. The software is better on the Uni-T (supports live usb webcam mode and has 3 movable points where it can measure).

[keenox]

Ran /etc/rc.d/usbcamerasetting.sh by hand and it works, but it only supports 15Hz. Also the live image on the cam seems to be 15Hz too.

@optotester: Here is the full flash backup from the C200 with 1.1.18: https://mega.nz/file/6FgyyJpb#XHXg4nk8ccflxwKWqsqqVM7w2DsnGWt9uyXsAUrCSIA

[keenox]

Also opened the UTi260B. Made a script that should activate the USB console when the update is triggered. Should work on the C200 the same.

PS: The UTi260B application works no problems on the C200
I'm so excited! These cameras have so much potential for hacking

Made review on C200. Bought with my own money. So far work very well.

[bebopdk]

Tried the script on my C200 V.1.1.10, and it looked like it ran(The display said "power off/reboot" after I ran it, but the USB serial port is non responding to any terminal command(the port was there before I ran the script, and was also non responsive before).

[keenox]

@bebopdk: From what I can see in the 1.1.10 firmware the upgrade is done by copying everything in the Upgrade folder, so I'm afraid you'll have to you optotester's script for that

@bebopdk: From what I can see in the 1.1.10 firmware the upgrade is done by copying everything in the Upgrade folder, so I'm afraid you'll have to you optotester's script for that

As far as I can tell: none of the scripts presented so far are working on my plain C200. Mine has Firmware 1.1.10 as to the menu. S/N C20020062533 acquired from "Guide sensmart Store" through Aliexpress on 2021, Nov 18th.

- It does not have UVC
- It does not have the selection between USB camera and disk in the menu
- It shows up with one device (see below) with three interfaces: CDC ACM and MS
- It detects files in folder Upgrade from the SD card and says you have to reboot

Upon Upgrade, in the Upgrade folder a file CalTempConfig.ini is saved.

With the usbdisksettings.sh from opto, no Backup is created, no getty is started. With Upgrade.sh no getty is started. It seems the scripts are just ignored or the getty is just not working. The CDC ACM is visible after booting the C200, but no response on commands.

The only 1.1.10 app that I have is from optotester and that has usb camera mode and copies files from the upgrade directory onto the internal flash.
The 1.1.18 app that came on my C200 has no usb mode switch option visible although the menu is present in the app code. This one runs the upgrade.sh script.
The 1.2.6 firmware from my UTi260B has the menu and an extra 3 custom measurement points menu. This one also runs the upgrade.sh script on update.

I could provide the 1.1.18 app and you can put it in the upgrade folder on your sd so it will update, but that will make your original app unrecoverable.
The best option would be to disassemble the camera and connect to the serial port on the PCB and then dd/copy the firmware to the SD card, activate the terminal on USB and then put it back together. That would be the safest option to preserve your original firmware and would benefit us more knowledge on the existing firmwares.

PS: Did you unzip the whole folder including the uti160e file?

OK, so you flashed the files from optotester to your device to confirm the usb camera?  I already have the 1.1.18 file from your camera as you provided a raw flash backup. I can mount the image file with both partitions and I looked around. Will have to disassemble mine, take a backup and compare with the image from optotester. I found /etc/UTi160E_config.ini to contain a line stating usb mode is "usbcamera" which is not true on your device. And in /root the file UTi160E_config.ini is empty, that is where the IRay_C200_Thermal executable is located. For the confusing file names, it seems that Infiray developed the camera core but the whole device including software seems to be developed by or at least for UniT? Then they branded it InfiRay again?

Currently comparing UTi and IRay, there are a lot of differences in the file system...

[keenox]

Did not flash it. Only copied his IRay_C200_Thermal executable where mine is and restarted the camera and it worked no problems.
Currently the /root/UTi160E_config.ini is not empty, but that might be because I played around with different apps.
That usbmode seems to be completely ignored by the 1.1.18 app that arrived on my A-BF camera. I disassembled it using ghidra, but didn't have time to understand everything that happens. The menus are there and are instantiated, but don't appear. There are also some menus for video recording and viewing and wifi(but the drivers are still on the flash, maybe used only on the proto/dev board?), but haven't seen those on any camera.

I think it might have been a commissioned project for Uni-T from the start and they decided they will also sell it under their own brand (and others, like mine which is A-BF). That's my guess, since uti160e is referenced in a lot of places.

[dl6lr]

Did not flash it. Only copied his IRay_C200_Thermal executable where mine is and restarted the camera and it worked no problems.

So you copied the executable from 1.1.10 to your C200 with 1.1.18 (from getty I suppose, or did you go the SD card upgrade path?) and that worked with usb mode menu and UVC mode without changing anything else? So maybe it is just compiled into the executable then.

I compared the init scripts and the difference is, the uvc drivers are loaded in /etc/rc.d/apps.sh (in the 1.1.10 files that opto provided) which is referenced from /etc/rc.d/rc.local. I assumed that the same executable was used for both cameras, C200 and C200pro, with only some configuration changes. On my camera the /etc/rc.d/usbdisksetting.sh never gets executed or it is never overwritten during the upgrade. The scripts name is only contained in Iray_C200_Thermal executable.

Will disassemble my camera one day and try to back it up from the terminal then.

[keenox]

I put it on the SD and copied it from terminal to /root. Did not go the upgrade path because I wanted to be as safe as possible and not lose access to the USB terminal in case something happens.
My guess is also that it is hardcoded into the executable, but I did not find any differences yet in the code where the menus are created and switched, but I did not have the time to properly analyze the executable. Maybe I will this weekend.

[keenox]

I managed to find the differences between 1.1.10 and 1.1.18. It is indeed hardcoded, the Qt signals for showing the menu are not connected. I managed to patch the binary to show the USB mode menu instead of device information, but upon switch it crashes. Needs some more work.

[littleboot]

Hi, It has been a while since I started this topic.
Very nice that people have found a way to extract the firmware. 

I have the C210 model, the device information page lists the following:
Model: C series
Version: V1.1.10

My camera does support the "USB camera" option.

If my understanding is correct after reading the comments, There is currently not a way to extract the firmware from this camera without opening it up.
For me there is no real need to take the device apart, it is working and I have all the features I need, but if someone needs it let me know.

I assume my camera is IMX6 based, not sure though ("C200 based on HiSi3516 platform, different for the C200/C210 from early batches which are IMX6 based")
Maybe it is possible to just load my C210 firmware on the C200 model to make UVC work?

[bebopdk]

Could be interesting to see the C210 fw and find out if it could be modified for the C200,
I ended up with a C200 even though I ordered a C210, but returning it would be a nightmare due to the non refundable VAT and taxes I paid for it , so I am kind of stuck with it, but having the webcam working would make me feel a bit less disappointed

[Ozzi]

Hi All,

I've ordered a c200 as well, but before it arrives i have been analyzing the 2 pictures (the IRG files) that were posted in this thread.
I noticed that the JPG data in these files are only 192x256 as well. Do you know if there is an option to get the full resolution in the irg-files?
Its kind of a waste letting all those extra pixels go to waste

[Ozzi]

For now I am able to generate the following image from the IRG-data:

[joe-c]

I have no InfiRay_C210, but i got 2 Frames to look at.
it have 192x256 as 2 byte per pixel.

I also have a "Vevor SC240" here, it stores *.irg files too and the format looks similar.

[Ozzi]

Yesterday I received my c200, it seems that I have software version 1.3.8
The data in the irg-files seem to be a bit different as well. I am also not able to open them with the IRAY software on windows.

[litchiate]

thanks, I should put stl file instead of sldprt file.

[RAPER]

Hey, is there any progress with the software update in c200/
A-BF RX-680 can you unlock uvc?

[rebotea]

Hi any code to read thermal image?

[duzycinek]

Hello, anyone have maybe firmware for C210? Sadly I got 1.1.6

[Honusnap]

Hi,

I received a C200 Pro and it's all in chinese, and no option in the menu to change to english ...
Is there something special to do to get it in english ?
I got firmware 1.3.8

Thanks

[Honusnap]

Hello,
Are you able to chose english langage for this device ? I got the same firmware and C200 Pro, it's only in Chinese .. !

[sab]

Has anyone had luck changing the date and time on the C210? Every time I change it, it defaults to 0101/1970 when I restart the device. I have firmware version v1.3.1(111).'

Perhaps there is some secret key or a long press that is required to save the date/time after I change it? I've tried but haven't had any luck.

BTW,  I did email support@infiray.com for new firmware and was told to to go to orders@infiray.com. No response from them though. And, the link previously posted on this thread is dead.

Thanks,

Sanjay

[Honusnap]

Hello All,
Still pinging here, do someone got a firmware for a C200 pro (or maybe not pro) Thankkkss

[painkiller]

Hi,

I just got a C200 pro. When I try to bring up the hiden menu to have a look, instead I think I brought up the calibration menu instead....I immediately press the back button to exit. but it seems something has changed. the temperature measuremnt and image is now off....I am cursing myself at moment.....

Is it possibe to restore a backup copy of the calibration from another C200 unit to the camera if someone have it?  I know it won't be perfect for my unit. But at least is should be close? Thanks a lot.

BTW, is that update_dat in the advance manu for restore the calibration?

[bebopdk]

The calibration is stored in a file named CalTempConfig.ini, it is unique to each camera, but the attached one is from a C200 V.1.1.10.

[Honusnap]

Hello,
Do you know a way to dump the C200 firmware ? Or maybe you already got a firmware update for a C200 ?

Thanks

[bebopdk]

It is mentioned earlier in this thread, you will need to connect via the internal serial port:

[Honusnap]

Hello,

This method do not seeems to work with recent C200 (i got a 1.3.8 firmwawre - C200 Pro)

[duzycinek]

Hello, my C210 is calibrating every 2-3 secs which make using it hard becouse of freezes. Is there option to make calibrating less often?

[Fraser]

That is evidence of a fault in the camera. It should only carry out an FFC every one or two minutes after initial “warm up”. The camera firmware initiates an FFC event if the ambient temperature changes significantly or a change in microbolometer die temperature is detected. There is also a routine FFC routine to maintain temperature measurement accuracy (the known FFC flag temperature is used as a temperature reference). This is often set to a 120 Second interval.

If your camera is still within warranty, return it to the supplier.

Fraser

[duzycinek]

Thank you for your answer! Sadly no warranty. I got no experience with repairing thermal cams, is there way to repairt it? What could be faulty?

[Fraser]

First check is to test whether the camera is making reasonably accurate measurements. This can be done in several ways but the simplest are below:

Check your hand (palm) temperature to see if it is somewhere near 32 Celsius. This is very rough just to see if the measurement is anything sensible

Check the water surface temperature in a boiling kettle. It should read close to 100 Celsius AFTER the kettle has stopped heating the water and the bubbling ceases.

Use a thermometer to check the ambient temperature of a room and measure the surface temperature of something non reflective in that room. The measurement should be close to that measured with the thermometer. Do not use a wall as the target as these suffer from influences beyond room ambient temperature.

Do remember to set a sensible Emissivity value for these tests. If you do not know the target Emissivity, go for 0.96 for these tests and it will be adequate.

If the measurements are way off then we can consider possible causes.

[Fraser]

Potential causes of regular FFC events rather than normal infrequent events

1. Failure or instability of the ambient temperature measuring circuit - this causes measurement errors as well.
2. Failure or instability in the microbolometer die temperature measuring circuit - this causes measurement errors as well.
3. Failure in the FFC flag drive circuit causing uncommanded FFC flag operations - this may, or may not, effect measurement accuracy depending upon the exact nature of the failure in the drive circuit.
4. Noise on a power supply rail that feeds the sensitive A to D circuits used in the camera. Such noise may create poor interpretation of analogue sensor inputs, such as temperature sensors. Depending upon the power supply suffering noise, this may cause image noise effects on the camera display. Cameras use several DC-DC converters and failures in the MLCC output capacitors are a possibility, causing high ripple on the related output supply voltage.
5. Firmware issue - unlikely in this case as the camera was working and then failed.

[duzycinek]

Thank you so much, I will check and post results

[Fraser]

It is always worth opening the camera and disassembling it for visual inspection to check for obvious issues such as corrosion but this also enables you to deliberately disturb the various ribbon cable connections and remake them as you reassemble the camera. Poorly seated Flat Flex Cables can cause all manner of weird symptoms as connections can become poor or intermittent. In your case, it is the Flat Flex Cable between the main PCBA and the microbolometer PCBA that is a possible point of failure as many important signals carried on that cable. A poor connection on it could cause havoc.

Fraser

[duzycinek]

Hello, I made measurments, all looks good. 98 for boiling water, 34 for hand, and object is about 2 degree warmer in reality. I noticed that after about 15 mins of using camera, calibration interval is like 30 secs, and it is increasing.

[Fraser]

Interesting.

The results of your test show that the camera is ‘aware’ of the temperature surrounding its microbolometer and the temperature of the microbolometer die. Sadly this is not great news as it eliminates the easily diagnosed issues that could be causing the symptoms that you are seeing

Some background on what happens when a microbolometer based thermal camera first starts. It is simplified but will give you an idea of what is happening and why.

1. The camera carries out a self test
2. The contents of the Flash memory are loaded into RAM
3. The camera starts its thermal imaging program and sub systems.
4. The temperature of the microbolometer die, and any Delta T associated with it, is measured
5. The ambient temperature within the camera is measured.
6. An FFC event is initiated to create a flat field image correction and to measure the FFC flag in order  to self calibrate the measurement system.
7. A Delta T in the microbolometer die temperature is detected and once it crosses a set limit, another FFC is initiated to both create a flat field correction and reset the measurement calibration offset using the FFC flag temperature. (using the ambient temperature as the source of the FFC flag temperature)
8. Another Delta T in the microbolometer die temperature is detected and the above process is repeated. This process repeats until the microbolometer die temperature reaches thermal equilibrium (in a non-temperature controlled microbolometer system). Once the microbolometer die reaches thermal equilibrium (internally generated heat energy is equal to that lost to ambient via conduction, radiation and convection (though convection is limited by the vacuum within the microbolometer module) the Delta T reduces to a point where no FFC event is required for some time. Temperature drift in the microbolometer die will occur and an FFC event will be triggered based on a detected excessive drift in the pixel temperatures, die temperature or change in ambient temperature. The camera will also carry out a routine FFC event to correct for minor pixel drift and measurement calibration. The routine FFC event is usually set to around 120 second intervals to ensure a decent image and measurement accuracy. The well known exception to this is the SEEK Thermal thermal imaging core that needs to carry out an FFC every few seconds in order to combat thermal instability in its microbolometer die. I know of no other thermal imaging core that requires such regular FFC  events, except upon initial power on whilst the microbolometer is warming up.

So from the above you will see that the bahaviour of your camera is anything but normal. Thermal equilibrium in a modern non-temperature stabilised microbolometer is normally achieved within 2 to 5 minutes and the FFC events become much less frequent after less than a minute. Your camera appears to be behaving as though it is suffering from a significant Delta T in the microbolometer die that continues long after it should have decreased due to thermal equilibrium being achieved.

If we consider the thermal stability of a modern microbolometer we may discover a clue as to what is happening in your camera. In most modern budget microbolometer based thermal cameras there is no Peltier temperature stabilisation of the microbolometer die, even if such is provisioned in the microbolometer module. A Peltier temperature stabiliser is a nice enhancement to a microbolometer thermal camera but it comes at the cost of increased system power consumption as Peltier modules are power hungry. Most  budget cameras operate in thermal equilibrium mode, as detailed above. It is important to employ enough thermal mass in the microbolometer to provide decent short term thermal stability, even if not stabilised at a fixed temperature. To achieve adequate thermal mass in the system, it is not uncommon to mount a large metal heatsink to the rear of the microbolometer module. The addition of the heatsink also helps to dissipate the heat being produced within the Read Out IC that is integrated into the microbolometer module. This is important as the enemy of the microbolometer is excessive local heating that can thermally contaminate the pixel array. If the heatsink becomes separated from the microbolometer it could cause temperature instability in the microbolometer and potentially create a situation where the FFC sub system is having to cope with excessive Delta T in the microbolometer die. Whilst the regular FFC events will try to maintain measurement accuracy through recalibration using the FFC flag temperature, there will, of course, be frequent undesirable FFC events for the user.

I suggest you dismantle your camera and visually inspect it for problems around the microbolometer PCBA area.

If there is not a problem with the heatsink coupling to the microbolometer, you are faced with the unwelcome possibility of a fault causing localised heating of the microbolometer die.

Fraser

[Fraser]

Having thought about this some more. I would also want to check all of the cameras power supply rails with an oscilloscope to ensure that there is not a problem in that part of the system. Power supplies are notorious for causing unusual bahaviour in microprocessor systems and should always be investigated for issues. The DC-DC converters will be easily identifiable in the camera on the main and microbolometer PCBA’s Why does the situation improve with time ? Good question ….. failures in power supplies can be influenced by temperature so warming up can sometimes change the fault behaviour.. well worth investigation.

Fraser

[duzycinek]

Hello, thank you so much for your help. I am trying to figure out what is happening. I will post my results

[duzycinek]

I did some progress. I found nothing suspisious after visual inspection on pcb, but I found out that microbolometer is powered by 2.1v after turning on camera. Voltage is decreasing by the time, at about 20 mins it is about 1.9V and then calibration interval is about 90 secs. So if voltage is lower, interval is higher, it is proportional. Sadly I can't figure out from where this voltage is comming from, I can't measure it by continuity (no beeps). I replaced thermal pads into high quality thermal putty, but nothing changed. Adding some photos.

[Fraser]

Where are you measuring the power supply to the microbolometer ?

I would have expected a 3.3V supply to the digital circuits of the microbolometer

The PCB is very similar to that of the UNIT UTI-260B topology. It is worth looking at the PCB behind the LCD panel as that has power supply test points detailed in the UTi260B and yours may have similar. If not, I can probably work out which DC-DC converters are which from pictures of the PCB. I can already see the Lithium battery charger IC and main 3.3V boost-buck converter IC on your pictures. There will likely be some DC-DC converters on the microbolometer PCBA onto which the Tiny1C module connects.

In case it helps, here is a post from the UTi260B thread where I detailed the various voltages and associated DC-DC converter IC’s used in that camera. Whilst the IC PCB numbering may differ, you may wel, find that the same voltages are present on your PCB from the same part number IC’s 

UTi690B/290B supply rails and their sources

Uni-T helpfully provide annotated test points for all of these voltages on their PCB's.

Main PCB

3V3 from U6 63025P
1V2 from U7 PD5Q
5V0 from U9 SF9B
1V35 from U8 PD5Q

Imaging cores PCB

1V8 from U2 PD5Q
2V8 from U3 NL

The UTi690B teardown images may assist you in cross referencing the functions of the various IC’s found on the PCB’s. The UTi260B and UTi690B share the same hardware platform. Whilst your cameras PCB does differ in layout, I suspect the components used for the power supplies will be the same or very similar.

Regarding a changing voltage on a supply rail…… look up the associated data sheet for the LDO or DC-DC converter that provides that power supply rail. If the change in output voltage exceeds the datasheet specification, consider that LDO or DC-DC converter worthy of further investigation. Modern DC-DC converters and LDO’s are normally pretty good when it comes to output regulation.

I was measuring voltage to gnd on flex from photo. Is not this power rail of ir sensor?. Did not measure yet 3.3v, 2.8v, 1.8v rails.

[Fraser]

The pictured Flat Flex cable is for the FFC flag solenoid and possibly a temperature sensor. It is not the main supply rail to the Tiny1C camera core.

[duzycinek]

I did some measurments. No good news. Voltages at start:
Main pcb:
Memory bat: 2.88v
Bat: 3.58v
L1: 3.18v
L2: 1.20v
L3: 1.36v
Sensor pcb:
3.3v: 3.23v
2.8v: 2.79v
1.8v: 1.88v

After 20 mins:
Main pcb:
Memory bat: 2.88v
Bat: 3.55v
L1: 3.20v
L2: 1.19v
L3: 1.36v
Sensor pcb:
3.3v: 3.23v
2.8v: 2.79v
1.8v: 1.88v

They are almost same. Only one voltage is changing, this one on flex.

Sadly I cannot suggest much more in the way of simple tests for you to carry out. I usually diagnose such faults on the test bench with tests and analysis of what is happening and why. I would certainly be looking at the temperature monitoring sensor outputs to see if they are triggering spurious FFC events. With regret, you have a fault that I cannot diagnose remotely.

Firmware issue ? Whilst you could try a firmware update as a last resort (the hardware appears stable enough for this to be safe), I doubt that this is a firmware corruption issue as that is normally more harmful to the operation of the camera.

I got 1.1.6 version of firmware, asked infiray for newer but they will not help me. I heard that I can flash Uni-t firmware but I got no experience with flashing, so I would need tutorial.

[duzycinek]

Hello, according to this video, it looks like it is firmware issue? Other person on video has also low interval. https://youtu.be/DIxhhA6T6ok?si=jLgcylIykTDvK7ID&t=1605

[bebopdk]

Does anyone have the original 1.1.8 firmware upgrade file? I'm trying to update mine, but as it is 1.1.10, trying to emulate the update only bricks the camera(I have serial access so I can unbrick it again).

[bingo600]

I have a C210 , still with the "original fw".
I'd also like "latest"  and how2 upgrade if possible.

I have TAS 1.11 , 1.14 , 1.15 & 1.16 here , that i could upload somewhere if they're of use.
I have tested none of them ...

@bebopdk
How did you get serial access ?
Via the USBC or ?

Any recipee for unbricling ?

[bebopdk]

I had to open the c200 and solder the FTDI 3.3v usb to rs232 converter to the pcb, from there it was straight forward, but it requires some Linux knowledge, managed to upload the v.1.1.10 from the board here and got webcam working, but only in the IRTP app, but better than nothing, if you fiddle, be sure to backup your calibration file first!!!!!!

[bebopdk]

Regarding unbricking, it all depends on how you have bricked the camera. I bricked mine(fw 1.1.10 w/o webcam) by emulating the update procedure there is in the IRay_C200_Thermal file, my goal was to update it to 1.1.18, so I took the required 1.1.8 files and put them in the Upgrade folder on the SD card and ran the update procedure, which worked, but bricked the camera and it was stuck on the boot logo screen.
After I soldered in the RS232 connections to the camera and got access via teraterm(usernames and passwords are also on this board), I could copy the files I had overwritten with 1.1.8 files back to the camera with the 1.1.10 files posted elsewhere on this forum, and this brought the camera back to life, with the added bonus, that the 1.1.10 files from the forum supports webcam(but only via the irpt program).
Before you do anything, make sure to backup the CalTempConfig.ini file, this contains the unique calibration settings for your camera!!!!
As a sidenote, I later got the 1.1.8 working on my camera(there was a missing file which I had to copy manually), but found out it did not support webcam, so I reverted it to the 1.1.0 again.

[bingo600]

My device is a C210 , not a C200.
I might just leave it as is ...

Btw: why all the secrecy wrt. login uid/pass ?

[bebopdk]

No secrecy, but there seem to be several different ones, so I found no reason for listing them all, root on the c200 I have is:
U:root
PW:uti160e

[jeffrond]

Speaking of different models C200 and C210, what about the C200+ or the C200SE+ or the C200 Pro+.  Looks like the pro+ has wireless. Any other major benefits to the + series?  Anywhere to order these in the US?  I have never ordered from AliExpress, is it safe?  Do you get what you order?
