What type of Board/Projector, or do you mean the interactive Panels without a projector?
Is the document camera connected to the PC, the Projector or directly on the Panel via HDMI?
From the fact that you mention the locker and the Camera app, I am going to assume you mean ActivPanel, rather than an ActivBoard/Projector? How is the camera connected?
If it’s connected to the PC that is connected to the ActivPanel, or any PC, you could also (wirelessly) share the PC screen with the Panel via the Screenshare app and control the Camera from the PC without any panel intervention at all.
