Dahua ARD2231-W2(868) | AirShield Wireless Dual-Tech PIR+Microwave Motion Detector | Black

Dahua ARD2231-W2(868) — Wireless dual-tech motion detector (PIR + microwave) for AirShield alarm systems

The Dahua ARD2231-W2(868) is a wireless dual-tech motion detector from the AirShield series, with a black finish. By combining passive infrared (PIR) and active microwave technology, false alarms caused by environmental factors such as temperature fluctuations or air currents are drastically reduced. An alarm is sent only when both sensors detect movement simultaneously. The device communicates via 868 MHz and Wi-Fi for a stable connection to the AirShield Hub.
