|Logitech C170 Webcam|
I have a couple of Logitech web cameras, which I have been loaning out to colleagues for teaching online, over the last few days. These are not as high resolution as newer cameras, but that can be an advantage. You don't need very high definition video for online teaching. I suggest not producing video for online delivery at more than 1280×720 pixels (standard HD). A webcam for that will cost about $AU60.
