>>4129433Whatever business grade plug-and-play monitor-topper logitech slop or whatever out there for say $100-200 will be more than enough. For cameras in general, but ESPECIALLY for this use case, the most important thing is good lighting. Invest some kind of bright constant soft light source (ring light, LED array panel w/ softbox, a fucking godox sl60 if you wish) you can angle ~45 degrees in front of and slightly above your face and basically any camera will look great, while even the best cameras in the world will look mediocre in a dimly lit office or bedroom or whatever. After that, maybe consider some kind of backdrop if there'd otherwise be a bunch of clutter in the frame.
If you insist on using a whole ass mirrorless camera anyways, look for ones that explicitly have the feature of being able to be treated like a webcam over USB by a computer. It's getting common in the last few years. It'll be easier than other workflows to capture the feed.
