The PG9984P Wireless PowerG Dual Technology Motion detector combines advanced PIR detection algorithms with K-band microwave detection to dramatically reduce false alarm events even in harsh installations. The PG9984P sends an alarm signal after both the PIR and the microwave sensors have detected an intruder, significantly reducing false alarms. The PG9984P uses a combination of elliptical parabolic mirror optics. An innovative mirror with extremely high optical gain delivers an extended range and provides superior detection sensitivity.
