Another option (although requires more tech) is to use the camera from a mobile phone connected to the computer via USB. Requires app + USB cable + "drivers" installed on the host computer. My teacher friend recommended DroidCamX (paid) but the drivers are windows only so I wasn't able to use that. I instead tested with Iriun https://iriun.com/ https://iriun.com/ and it worked OK with my newer phone (the older phone I wanted to use had trouble with autofocus... though maybe that's because of the way I have it suspended from a desk lamp). It lags a little, but overall usable.
