Hey everyone,
I recently picked up a Mileseey TNV256I USB-C thermal camera off amazon for a pretty good price ($125). I'm looking to use it for some RPI projects im working on, but the documentation and resources are quite lacking. I can only seem to get it to work with the OEM app, no luck using any other thermal imaging apps. I can't seem to get any sort of image connecting it via PC. It shows up as a USB device labeled "Mars", but there are no drivers and I cannot view it through virtualDub, TOPDON, or similar applications.
Does anyone have additional information on this thermal camera?
Here is a link to the camera on the manufacturers website:

Thanks

whats the usb Vendor and Product id ?. (device manager, click on "mars", properties, details, dropdown to Hardware id's.
you could try installing / replacing the driver with usbvideo.inf found in c:/windows/inf
not sure about linux tho.

Vendor ID: VID_4206
Product ID: PID_3702
I've tried installing drivers for it using the windows usb camera driver, tiny1c, and tc001 files. Unfortunately none of them worked :(

Cant find anything about the Vendor id except a company called "ConectL"
but in the android code it suggets it to be a core made by Guide.. https://www.guideir.com/ (https://www.guideir.com/)
tried decompiling the APK "com_dy_tlfa_wcc_tnv256i_v1.3.10" with jadx-gui and found the following:
it directly interfaces usb and sends / reads trough endpoints.
0x83 ADDRESS_ENDPOINT_CONTROL_IN data coming from the camera, probably telemetry etc. 17 bytes (1 head, 2 cmd, 1 reserved, 4 length, 4 cheksum, 4 data, 1 tail)
0x81 ADDRESS_ENDPOINT_DATA_IN video data probably
0x2 ADDRESS_ENDPOINT_CONTROL_OUT (size variable) to set stuff like palette, brightness, emissivity etc.
nevertheless it doesnt seem to utilize the USB HID / UVC class at all
unless someone with a little more programming skill than me (and has a mileseey camera) writes a python script that interfaces with it directly it wont work on a PC.
its certainly possible and should even work on a Pi.
you could try the apps provided by Guide:
