The Hikvision HiLook HA-ALARM-PIR2-AUS is a wired dual-technology motion detector combining passive infrared (PIR) and microwave sensing. It offers a 12-meter detection range, 30kg pet immunity, and advanced false alarm prevention features, making it ideal for both residential and commercial indoor security applications.
The HiLook HA-ALARM-PIR2-AUS is the “heavy-duty” alternative to the standard PIR1. While the PIR1 is a single-technology sensor (Infrared only), the PIR2 is a Dual-Technology detector.
This is the sensor you choose for “trouble” areas—like a garage with high temperature swings or a house with a medium-sized dog—where a standard sensor might trigger a false alarm.
