Once can use ceiling document cameras for conferencing rooms, meeting rooms, training rooms and classrooms where you have to hide the document camera. Since no work surface or table and cables are required, the interaction between presenter and audience is not disrupted.

Some desktop document cameras have inbuilt small LCD screen (3 to 6 inches) that shows how the image will look like before being shown on TV or projection making it easier to focus and position the object at right place.
