Multi-Sensor Fusion Replaces Single-Technology PIR Detection
Manufacturers are combining passive infrared, microwave, and increasingly ultrasonic detection within a single fixture to eliminate the false triggers that damaged confidence in early motion-sensing lighting deployments across commercial and outdoor applications. Dual-technology fixtures now reduce false activation rates to under three percent, compared to rates several times higher for single-technology PIR units operating in windy or high-traffic outdoor environments. This shift is pushing average fixture prices higher, but facility managers increasingly accept the premium since fewer false triggers directly reduce energy waste and nuisance complaints from building occupants and neighboring properties.
Market Impact: 35+ US states now mandate sensing
