Bill, behind "ThermAppPlus" (a app developed with the Therm-App SDK) has updated it with a few image processing enhancements for enhanced image quality.

I made some test shots to test these enhancements. Note the thermal span is around 2 degrees for maximum noise to show the improvements made by the app.

No enhancements applied. The Opgal app would show the same image.


"background noise correction" applied. Essentially a manual NUC to correct the static background pattern.


A temporal noise reduction applied too. It reduces the slight horizontal banding (which I assume to be readout noise) present at low temp spans.

If you've been eyeing the Therm-App and think that $939 is too much, then perhaps this is of interest to you.

Looks like the Black friday deal is free international shipping on all products, coupon "Black2015".

For the basic Therm-app that works out as a ~6% discount.  :(

I guess for people wanting to order lenses it's a pretty good deal.

Yeah, it's a bit disappointing :(

I would buy a lens, but the only f/1.0 lens available isn't wide angle enough for my liking. I want a wide angle lens for night vison / thermography, and low f/stop for lower noise.

The therm-app TH seems to be the best option for electronics work? Doesn't seem to show up in their shop section though...

Yeah, you need to contact them to buy it. Although if you don't need absolute temp accuracy just go with the Therm-App.

Oops, I didn't realise that post was from last year.

Either way, could someone please move this thread to the Thermal Imaging subforum?

I am looking for a thermal camera and plan to keep it at around $1k
I seen this one the non TH for about that and the TH is a little bit more.
I been looking into the flir e4 as it can be hacked as well.

Any one here have both and can post side to side photos. As some older pics in here are not showing up.

I dont know if i will regret not spending the extra 500 or so to get the therm-app TH over the flir e4+

Any updates thanks.

How accurate temperature measurement do you need (and to what limit)? Perhaps you could get by with a Therm-App non-TH.

I guess not acurrate as far as temp reading goes, but good image to look around at anything, from wall, ceiling to electronics, people. And be able to see water spot on ceiling that way i would know if there a leak on the roof.

In that case, there will be basically no difference between the TH and non-TH (assuming same lens). The image produced will be the same, just that the TH will have more accurate readings / read higher temperatures.

In fact, if we use the included lenses (ie. the 6.8mm f/1.4 one that comes with the TH and the 19mm f/1.1 that comes with the non-TH), the non-TH will actually generate a dramatically better image due to the larger aperture.

It's far more worthy to spend your money on the 13mm f/1.0 lens ($250) instead of the TH. The f/1.0 aperture will allow in more IR light and actually get you a better picture. In fact, the f/1.4 lens that comes with the TH is a full stop slower than the optional f/1.0 lens, which means the f/1.0 lens allows in double the light.

When importing thermal cameras I have had to pay the following customs fees in the UK......

2.5% Duty on IR camera technology.
20% VAT on total cost including postage cost.
£12 paperwork.processing fees from the courier company.

While it would be nice to have a Seek vs TA comparison, I think what most people want here is a battle of the <$1K 320x240-class thermal cameras.

However, I don't think that will happen unless someone wants to pony up the money for a Therm-App, ThermalExpert and FLIR "E4".

Here's some video I shot using the Therm-App at night. It really shows off the level of detail the camera can achieve.

That is creazy. :-+ It looks like it was taken with regular camera in black&white mode.

Nice video thanks.  It also shows the apparent benefits of the human eye-brain temporal filter (around 10Hz depending on the individual) at cleaning up or ignoring certain types of noise.  Still frames and colourised video will always look worse.

Also of interest is the difference between black and white hot in overall image presentation, ease of interpretation and usefulness. 

It should be possible to trade between the two with a mix of image gamma and adjustment of the thermal mid point (in contrast modes) or histogram centre (if equalising) but this is very scene dependent.

I am really considering buying this camera. The only thing right now holding me back is how wobbly the video is. I am aware of why it is happening, I just wished they would have used a full frame instead of a weird delayed progressive scan technique. I saw the video where each frame was morphed together and the effect makes it look very fluid like a full speed camera. If we could do that real time then it would be an amazing camera.

Same video except with frame interpolation to smooth it out to 30fps.

The Therm-App is now avaliable for sale on Amazon (well, kinda - it appears to be out of stock).

http://www.amazon.com/Therm-App-TA19A17Q-1000-Thermal-Imaging-Device/dp/B00O7HUJSK/

(it's currently showing a higher price because it's showing a third party reseller since the direct from amazon products are out of stock. click the "2 new from $1100" to view the "sold by amazon" price).

http://www.amazon.com/Therm-App-TAH68AQ-1100-Thermographic-Imaging-Device/dp/B017I4P5B4/

The Therm-App TH is also avaliable for $2000 (also out of stock atm)

Hi Eddy, I'm interested in your code for importing Therm App images into Flir Tools. I see your post about steps for it. But I'm not a computer guy and don't know much about the PHP. Also I'm using the official app on my phone (instead of ThermAppPlus). So will your code provide a convenient way to do the importing? Or will it be available for downloading? Thanks in advance.
