That effect is common in Microbolometers with a BST sensor, however what's going on in the Therm-App is completely different (The therm-app doesn't use a BST sensor).

That artifact is a result of using the stock Therm-App app in "Night Vision" mode. This mode works to use image processing to exaggerate temperature differences for a more detailed image at night. Sometimes the image enhancement goes a bit overboard and causes the halo. However I think this is on purpose and can be useful as if you had, say, a warm person on a background with only slightly lower temperature, it would be very hard to see the person. However, with the image processing, the slightly warmer person will have a black halo around it which makes them much easier to detect.

Personally I use the "ThermAppPlus" app on the Play store, which has other image processing enhancements for lower noise (as I generally use the Therm-App for thermography), however I guess the night vision mode in the stock app results in increased detail.

I'll post a comparison soon.

Encryptededdy, thanks for clearing that up for me.  The therm-app's detail is incredible for its cost, it's too bad the Black Friday deal was only for shipping :(  I guess I'll have to wait a bit longer and see how the ThermalExperts stacks up with it. 
Another thing I've noticed specifically with the Therm-app is when the camera is moved around, like in your parking lot video, there is a screen-tearing effect that makes it look like its underwater.  Does that get annoying for you or do you get used to it?  I do notice the effect isn't present or at least as noticeable on the 25hz model.  I wonder if it's to do with reducing the frame rate to 9hz on the base model and if it's something that can be addressed in software.

You get used to it, but I don't really use it for Night Vision so I can't really comment on that.

It's due to how they reduce the frame rate to 9Hz - Cameras like the FLIR One or FLIR E4 read out at 30fps then drop frames to get 9 fps.

The Therm-App reads out at 9fps, therefore taking 1/9 of a second to scan the whole sensor, thus leading to the jello effect. Personally I would much prefer it if they read out at 30fps then just dropped frames, however they claim that this way you're less likely to miss something (as everything being read from the sensor is displayed). I guess that's technically correct, but it certainly looks ugly.

Guys, I have a Problem with my flir one  :-\

I bought this baby yesterday, charched it and it worked well! but today as i unplugged it from the power brik it wont turn on  :-//

does anybody knows if there is a "lock"-mode on this device? :(


edit: when I plug it on the power brick, the green indicator-light stays dark :(
