Dear thermal imaging enthusiast and hobbyists!!

I’m in middle of the process of evaluating this device’s capabilities so I’m reaching out: Could someone DM me some raw, uncompressed photos taken with SC240M? Especially interested in photos taken with the model with camera module.

Photos of interest to me are those taken from inside of apartment buildings, documenting temperature differences near window, vents, doors and bathroom floor/drains. Also curious to see how the apartment buildings look from outside-in. In this case, more is more so if you can provide multiple photos, I would greatly appreciate it!

My goal is to better understand the capabilities of the device: resolution and sensitivity in apartment and building context.

Here is my e-mail for image delivery: mazurka_spinach.0@icloud.com

Hi all!

Looks like my C200 Pro on Hisilicon HI3516DV300 platform is dead.

The thermal image looks very noisy and there are a lot of lines. And this is not a problem with the screen - the picture from the video camera and a menu are absolutely normal.

The camera was used for amateur purposes for about 2 years, about once a month. I guess not more than 3 full battery charges.
What's confusing me, is that the problem first appeared after two months. I wanted to use the warranty, but the camera is self fixed after the battery was completely discharged and then recharged. And then it worked perfectly. Until a few days ago, the problem arose again and it can no longer be solved with simple methods.

FFC events (shutter sound) occur frequently at powering on, but after a while everything goes to once per one/two minutes - looks normal for me.
I disassembled the camera, checked and cleaned all ribbon cables - no luck. 
All voltages on both boards are OK, the oscilloscope shows no noise on the capacitors.
The RTC battery is completely dead, it doesn't even charge, although 3.2v present, when the camera is on.

Judging by the attached log and numerous messages
"[1970-01-01 00:00:12][LIB]: HisImageProcess error."
unit experiencing problems communicating with ELF1 (thermal module) image processor.
I guess troubles even not with the connection itself, but processing of the received data.

But thermal image is alive, i can see the outline of my hand, the center point showing like the right temperature. But there is a lot of noise from the min to max values of the measurement range at the same time.

Masking different lines in S90start I found out that "HisImageProcess error" occurs when launching /iray_app/iray-hisi-camera, which initializes the communication with the thermal module and eventually displays the thermal image on the screen. The problem is exactly in this place. And only after that /iray_app/iray_softer_01 - the user shell - is launched, but this does not change anything in the corrupted image.

Fraser, can your wealth of experience tell - if this is a hardware or software problem? I think it's faulty thermal module/integrated image processor...

By the way, there are 8Gb eMMC disk and 512M RAM inside - quite a powerful thing.

Fraser:
Evolver,

That looks like a nasty fault. As to whether it is hardware or software that is causing it, I cannot be certain. This fault would need some detailed investigation of the signals coming out of the microbolometer module.

Fraser

Evolver:
Thank you.
I suspected that there is no easy solution here. So I bought another one full clone of that camera Mileseey TR256B. It can be included it in the topic title. The only difference from C200Pro is a body color, even measured weight is same. At least if it breaks too, I can assemble one frankenstein from parts of two ones  :).
