The PG9974P Wireless PowerG Mirror Optic PIR Motion detector is a vital component of a security system. Upon the detection of motion, the PG9974P communicates an alert to the security system. Additionally, the PG9974P provides immunity from pets weighing up to 40 kg (90 lb) to reduce false alarms. Using advanced technologies, the PG9974P provides reliability, robustness to interference, prolonged battery life, extended range and easy installation.

The PG9974P uses a combination of elliptical parabolic mirror optics. This innovative technology creates an exceptionally efficient mirror with extremely high optical gain, delivering longer range and providing excellent detection sensitivity. The PG9974P also applies a digital temperature compensation that allows the detector to continuously adjust its sensitivity according to the location temperature. In this way, the PG9974P is able to detect an intruder even when the ambient temperature is close to that one of the human body.
