A cheaper but somewhat more kludgy solution is using an old camcorder with a line out and converting that to USB. I had an old camcorder laying around (a samsung https://www.samsung.com/ca/support/model/SC-MX20/XAC/ https://www.samsung.com/ca/support/model/SC-MX20/XAC/ ) with composite out and I also had a composite to hdmi converter and another to convert hdmi to usb. (they also make composite to usb all in converters) I found the box for the samsung camcorder and I still had the RCA output cable. Chained them all together and windows sees it as a usb camera. Works without a hitch so far.
