OPTEX BXS-AM(W) Dual-Side Outdoor PIR Motion Detector with Anti-Masking (4 Beams, 24m, IP55)

This OPTEX BXS-AM(W) is a professional dual-side outdoor PIR motion detector engineered for high-security perimeters. It delivers reliable detection with four independent beams—two per side—covering up to 24 meters across an area, while its active anti-masking technology blocks sabotage attempts.

Advantages

The detector uses SMDA (Super Multi-Dimension Analysis) logic to distinguish human movement from environmental disturbances, drastically reducing false alarms. Its active IR digital anti-masking monitors the lens for obstruction, ensuring continuous operation. The IP55-rated housing withstands harsh weather, and optional sensitivity and day/night settings provide flexible installation.
