Duet AMis a smart high-security dual-technology detector that combines digital PIR and microwave technologies with anti-masking to optimize intrusion detection for industrial environments. It is designed to expose efforts to intentionally or unintentionally defeat the detector.

Duet AMcontinuous monitors its surroundings and issues alerts whenever its field of view is blocked. Self-testing is periodically performed by unique patented microwave and passive infrared "Motion Simulators". If the detector does not respond appropriately to the effects produced by these motion simulators, malfunction alerts are issued.
