Abstract
A motion detecting system including a plurality of transmitter housings. A plurality of motion detector transmitter mechanisms are situated in each of the transmitter housings. Each motion detector transmitter mechanism includes a motion detector adapted to emit a motion signal upon the detection of motion, a transmitter adapted to emit a transmitter activation signal via free space upon the transmission of the motion signal and only during the receipt of power, and a one-shot multivibrator mechanism connected to the motion detector and the transmitter. The one-shot multivibrator mechanism is adapted to transmit power for a predetermined amount of time upon the receipt of the motion signal. Further provided is a receiver unit including a housing and a receiver mechanism. The receiver mechanism includes a receiver adapted to accept the transmitter activation signal via free space. At least one light emitting diode is situated on the receiver housing and is connected to the receiver for indicating the detection of motion by at least one of the motion detector transmitter mechanisms.
