I’m not sure what makes a good webcam, as I’ve never shopped for or owned one. The one camera I do own, is the Intel RealSense camera that I bought for using with Windows Hello. As near as I can tell it works fine as a camera, it has no mic… does a webcam include one? Anyway, I mention it not because it’s the best camera possible, but because it may be possible to actually acquire one:
EDIT: It appears they no longer include a monitor clip with them (mine came with one) so you’d need to sort that out, one option is: https://www.bhphotovideo.com/c/product/1336208-REG/marshall_electronics_cvm_5_universal_1_4_20_camera_clip.html
I don’t presume this one is purchasable either:
