Sandberg USB Webcam Saver is perfect for online meetings. It works instantly without driver installation. The camera sits on a clamp to attach the camera easily on a laptop screen and the like. The camera features also microphone.

NB - this item is new, but the microphone quality seems to be poor so I am giving it away in the hope that someone can use/fix it.
