Chat with others with using capture board connected with normal PTZ camera(Not with webcam)
Most people use webcam for live chat.
But some place, like where has already camera systems, the user in this place would want to use their camera while using PTZ(Pan/Tilt/Zoom) with capture board.
In this case, the camera resolution wouldn't be improtant.
The importan thing would be the compatibility with their camera systems.
If they use multiple cameras with switcher, that would be very useful.
