The 650' SmartLine Series SL-650QDP Dual-Modulation Quad-Beam Photo Detector from Optex consists of an IR transmitter and an IR receiver. The transmitter and receiver are installed on opposite sides of the area to be monitored. The receiver detects when the IR beams are physically interrupted by an intruder and sends an alarm signal.
