Dahua Technology DHI-ARD1731-W2 Intruder detector Specifications

Dahua Wireless PIR-Camera Intrusion Detector

Product Profile

The Dahua ARD1731-W2 Wireless PIR-Camera features a built-in 2 MP CMOS image sensor that captures high-definition snapshots when an intrusion is detected. The images are transmitted to the alarm hub before being sent to a mobile app or alarm centre (CMS/ARC), enabling visual alarm verification.

The camera uses 2.4G RF-HD transmission technology to improve image resolution and transmission speed. To protect user privacy, it only captures snapshots when an intrusion occurs.

The device supports IR detection and video review, with a maximum resolution of 1600 × 1200 and quick image transfer. It offers a one-week cloud cache for videos and images, an IR illumination range of 12 m at night, and multiple resolution modes.

The detection range extends up to 12 m with an 86° viewing angle, and it includes a pet immunity function, automatic temperature compensation, and three adjustable sensitivity levels. Additional features include a low-battery warning alarm, temperature monitoring, and frequency hopping with two-way communication technology for stable communication.
