Dahua ARD2231-W2 - Wireless Dual Tech Alarm Detector

The Dahua detector ARD2231 new industrial design and an advanced technological system

The Dahua DHI-ARD2231-W2 (868) detector is a dual-technology wireless motion detector designed for use with Dahua alarm systems operating on the 868 MHz frequency band. It combines passive infrared detection (PIR) with a microwave in a single package to reduce false alarms and increase detection reliability. This dual technology allows motion to be confirmed only when both sensors are activated, improving accuracy, especially in sensitive environments.

This detector is intended for indoor installation, mounted on the wall at an optimal height and orientation to cover the desired area. It is particularly suitable for home or professional spaces where reliable motion monitoring is required. It communicates with the alarm panel via a secure two-way radio link in 868 MHz, using encryption and frequency hopping techniques to ensure the confidentiality and stability of the transmission.

The detector is powered by built-in batteries for extended battery life and is designed for minimal maintenance. It has an LED indicator to view the operating status and trips. For protection against tampering, an anti-tamper contact is integrated to signal any unauthorized opening or attempted removal.

Installation is easily done in a wall position, with an adjustment that optimizes the detection field. This detector is suitable for residential and commercial environments that require accurate, reliable, and wireless monitoring of intrusive motion. If you want, I can also provide you with a version in the form of chips with technical characteristics.
