Dahua DHI-ARD1731-W2(868) Wireless PIR-Camera

The Dahua DHI-ARD1731-W2(868) is a wireless PIR motion detector with an integrated 2MP verification camera, designed for use with Dahua wireless alarm systems. When motion is detected, the device captures high-definition images and transmits them to the alarm hub, enabling visual alarm verification and helping users quickly determine whether an alarm event is genuine. This significantly reduces false alarm responses and improves security monitoring efficiency.

Combining passive infrared (PIR) detection, built-in infrared illumination, pet immunity, and secure two-way wireless communication, the detector is ideal for residential, commercial, and light industrial intrusion detection applications.
