There are many cameras sourced from China that seem to be rebrands of the same item. A mere sample of Amazon links includes
[SJCAM](https://rads.stackoverflow.com/amzn/click/com/B078SS1RND)
[AKASO](https://rads.stackoverflow.com/amzn/click/com/B01HGM33HG)
[Campark](https://rads.stackoverflow.com/amzn/click/com/B01MXXP4EC)
[COOAU](https://rads.stackoverflow.com/amzn/click/com/B07DWP3M46).

There are many more. I don't know what electronics are in them, but they sure appear to at least use the same enclosure and lens.

There is [one Ask Ubuntu question](https://askubuntu.com/questions/611664/sjcam-sj4000-not-recognised-by-pc/656976#656976) already, which seems to indicate that this type of camera worked in a previous version, but no longer does.

What I would like to do is use the USB3 cable to connect such a camera to my PC and use it as a webcam. None of these inexpensive cameras are listed in the gphoto database of Linux-compatible cameras.

Any assistance would be appreciated.

Edit: another [existing Ask Ubuntu question about the same camera](https://askubuntu.com/questions/1062440/webcam-not-recoginized-on-18-04).
