Dahua AirShield Smart Alarm Wireless PIR Detector

The Dahua AirShield Smart Alarm Wireless PIR Detector is a wireless motion detector for Dahua smart alarm systems. It is designed to detect human movement within an armed area and send timely alarm event notifications when movement is detected.

The detector uses a dual-element low-noise PIR sensor with a detection range of up to 12m at 90° when installed at a height of 2.2m. This makes it suitable for indoor spaces such as villas, shops, apartments and similar properties where reliable movement detection is required.

To help reduce unwanted activations, the detector includes pet immunity for animals up to 18kg, 3-level sensitivity adjustment and automatic temperature compensation. It also supports temperature monitoring, with a measuring range from -15°C to +65°C and ±1°C measuring precision.

Wireless communication is supported through two-way communication technology, AES128 encryption and frequency hopping to help maintain stable connectivity. The detector also includes signal strength detection, low battery alarm, tamper alarm, test mode, cloud update and automatic recovery from update failure.

Powered by a CR123A battery, the detector provides up to 4 years of battery life. It is wall mounted, housed in a PC + ABS casing and designed for indoor operating temperatures from -10°C to +55°C.
