I just registered a account and try to set up the camera. After I installed GradeCam Plugin, I go to the second step: select Camera. it doesn't show any camera in the dropbox, only one is default. When I login to my account, it shows alert information in a box: " Alert: Camera Error: No camera detected" .
My computer is connect to a document camera: AVerVision300AF+ it is in the compatible list. My computer and document camera is connect the way for classroom instruction(allow me to show both computer and document camera through a projector by a switch).
