Using a Campark ACT74 action cam as a webcam in macOS 10.12

I recently got a Campark ACT74 action cam , with the intention of using it as a camera with which to live-stream stuff to Twitch and the like. Upon plugging it in to my Macbook Pro (2015, 10.12) --- nothing happens. It doesn't appear in OBS, PhotoBooth or QuickTime, despite selecting the "PC Camera" option when prompted by the camera upon plugging it in. I tried getting it to work with the open-source "macam " software, but that didn't recognize it either. How can I make this camera work with macOS?
