Most General Purpose Classrooms are equipped with wall or ceiling-mounted PTZ (pan, tilt, zoom) cameras that serve as a camera source for the in-house PC. The camera position can be adjusted from the touchpanel, and presets can be saved, allowing quick recall of frequently-used positions. Audience and instructor cameras can be selected on the touchpanel, which will automatically feed to the PC via USB, without having to adjust your camera input within your software.
