Just a note - I had a Nokia D90 dslr that would overheat if left in video mode for too long (over 5 minutes). Check for any "max video recording length" mentions on the camera's spec sheet as a early sign that this might be the case. A "yesteryear" smartphone that is collecting dust is also an excellent alternative, as they have surprisingly high quality cameras and lenses (on the rear side, anyway). I use a cracked-screen-not-worth-repairing Xiaomi Mi Mix 2 (about 5 years old now) placed in an amazon ring light (that conveniently has a phone-sized clamp-style mount in the middle). There is an android app that turns the phone into a network-accessible webcam, and a windows app to receive it and map it as a system camera input. Quality (resolution, field-of-view, focus and light levels even with very bright background) is miles ahead of my logitech brio 4k webcam - to the point I resold the brio after only a few days. I can actually stream in 2160p from the device at a pretty respectable framerate. Probably not on par with a modern DSLR but for something that most people I think have laying around - highly worth trying first.
