The microphone should be placed at the front of the table to ensure that all speech will be
detected. The best position for the microphone is at least 2 meters (6.5 feet) in front of the system
on a plain, flat table with at least 0.3 meters (12 inches) of table in front of the microphone.
The document camera should be close to the chair person or a designated controller of the
document camera for ease of use (remember to arrange all the peripherals so that one participant
can reach each of them to point, change the display, tape, and so forth).
The camera supports up to 15 pre-stored camera positions.
The illustration shows three possible camera positions; one for all the participants, one for the
whiteboard and one for the main speaker. The remaining camera presets are then available for
other peripheral equipment, for example a VCR.
Position the system in such a way as to avoid the possibility of somebody inadvertently walking
into the camera’s field of view when entering the room. Other than the conference participants,
there should be no moving items in the sent image.
