Many online sources were out of stock or had long shipping delays. I was able to find a solid webcam on eBay with an integrated microphone. The USB cord is 6 feet long, which is more than adequate.
I found zero reviews of this thing online, so I decided to write one. It was made by Kryterion for online testing, so the proctor can watch you as you take the test. It has a USB connection and connected to my windows 10 PC with no issues at all. The video resolution is adequate, and it can be focused by turning a ring around the camera lens. The camera with integrated microphone is attached to a flexible neck, in turn attached to a weighted base.
Overall for $16 shipped I am happy with my purchase. The mic picks up fine and I like the adjustable neck. It worked flawlessly with zoom, even when I disconnected and reconnected the USB connector during a call. The video and sound came right back.
I am not the eBay seller of this item and receive no compensation for your purchase. Take care and God Bless!
