Abstract
A projector signage and control system (10) for displaying a sequence of images onto a display screen (18). The projector signage and control system (10) is designed to monitor and control the operation of a projector (20). A projector control circuitry (14) is provided for enabling and disabling a projector (20) dependent upon levels of ambient light. In the event of a failure, a monitoring circuitry (16) seizes a telephone line (106), calls a predetermined number, and delivers a pre-recorded message such that appropriate actions may be taken. These events include the raising or lowering of the temperature within the projection system cabinet (26) to a temperature outside of a predetermined operating range, the sticking or other malfunction of the projector tray (24), the burning out of a bulb, a power outage, and the tampering of the projection system cabinet (26).
