Description
infrared beam detector .Install Every pair at the opposite positions.Then there’s a infrared area between these two detector parts. When someone passes the infrared region, the detector will send alarm signal.

Key Features and Types of Infrared Beam Detectors
n
-
n
- Active Infrared Detectors(AIR): Consist of a pair of devices (transmitter and receiver). The transmitter emits a pulsed IR beam, and the receiver triggers an alarm if the beam is broken.
- Detection Range : Available for various distances, ranging from short-range (30m) to long-range (100m+) perimeters.
- Dual/Quad Beams : Advanced models use two or four beams simultaneously. An alarm is only triggered if all beams are interrupted, which helps ignore small animals or falling debris.
- Environmental Adaptation : High-quality detectors automatically adjust beam power to compensate for fog, rain, or dirt on the lens, ensuring consistent performance.
- Application: Widely used on fencing, windows, driveways, and for gate safety in automated systems.
