Decent webcam for streaming under 100?

If you do go with the C920, set exposure and white balance manually in the settings software or OBS. On auto it hunts constantly and the image flickers every time you move. 1080p30 is plenty for a facecam.

At that price your phone probably beats any webcam if it's from the last few years. Bigger sensor, much better processing. iPhone works natively on a Mac, and on Windows there are apps that turn the phone into a webcam for OBS. Just get a cheap clamp or mount for it. If you want something plug and play, the Logitech C920 is still the safe pick and usually well under 100. Honestly though, spend 20-30 on a small light pointed at your face. Lighting fixes more of the "looks awful" than the camera does.
