Monitor indoor/outdoor perimeters without setting off false alarms by installing the Optex Quad Beam Photoelectric Detector, 350'/650'. This quad beam detector includes a beam receiver and beam transmitter that provide reliable detection with a quad beam detection pattern. This design dramatically improves detection and helps prevent flying birds or falling leaves from triggering an alarm. Plus, high-grade aspherical lenses are used in its design, creating more precise active infrared beams.
The Optex Quad Beam Photoelectric Detector has a slim body design and is lightweight. It includes a beam blocking plate that can be fixed on the lens unit securely so that it won't be easily blown away by wind and has an anti-frost hood design (on both the upper and lower beam) to help prevent frost from attaching to the front cover.
