Some notes while talking with the Seek Thermal Camera.
I just ask for Frames, and the Imagemode of the camera set how the camera works:
1 "raw" Mode
Frame types: 3,3,3,3,3,3,3,3,3,3,3,3
the Camera delivers just a Frame of the Sensor, without processing. there is no shutter and no compensation of the Warmup. so start and work in raw mode will let single pixels go out of rage. but with a thermal stabilised camera, or just use raw mode after warmup, you just get frames without shift. a good way for external 2point calibration to enhance the image quality

Frame types: 3,3,3,3,3,6,1,3,3,3,3,3
this is the working mode while using the App. it delivers a frame and after a internal time period the shutter rises.
frame id 1 and 6 are closed shutter calibration frames.
if you manually (or with higher time) get frames, you get 3,6,1,3,6,1 because how much time the camera deliver normal frames with open shutter was handled internal.
if you remove the frame ID 1 from frame ID 3 you will get a usable image
if you remove the frame ID 6 from frame ID 3 you get a usable image, until the Pixels start drifting.
I guess it work like that: before frame ID 1 was delivered, the ADC Gain for all Pixels was updated (to keep all Pixels in valid range).
so there is no direct control of the shutter. I tried some commands but without success. therefore you just can handle what the camera delivers in normal mode. In Raw mode (without processing) you can do more external stuff, but there is no update for the dynamic range of the ADC for the Pixels, so the Camera have to be in a temperature stable condition.
