Lighting Normal conference room lighting is not adequate for videoconferencing. If the background is too dark and contrasts with the lighted images, the camera is unable to adjust its iris properly and may cause objects to appear out of focus. Glare from normal lights can reduce the sharpness of monitor images.
Poor lighting can accentuate light colors or create dark shadows under participants eyes.
The transmission of good quality images depends on special lighting. Two by four foot light fixtures. Electronic ballasts to reduce the noise generated from the lamps. Control this lighting with a dimmer switch. Illumination of the back wall as well as the participants.
