Dahua DHI-ARD1233-W2 (868) black - Wireless PIR Alarm Detector

The Dahua DHI-ARD1233-W2(868) detector with a new industrial design and an advanced technological system

The Dahua DHI-ARD1233-W2 (868) detector is a wireless motion detector designed to be integrated into Dahua alarm systems operating in the 868 MHz band. It allows you to monitor movements in a defined area and trigger an alarm in the event of an intrusion. The detector combines passive infrared (PIR) technology with digital processing to reduce false alarms caused by pets, light, or other sources of disturbance.

This device is intended for indoor installation, with wall or corner mounting to optimize room coverage. It communicates directly with the alarm center via a secure two-way radio link, using encryption and frequency hopping to ensure the reliability and confidentiality of the data transmitted.

The detector is powered by built-in batteries, providing long-lasting battery life, and has an LED indicator to signal device status and alerts. It is also equipped with an anti-tamper contact that triggers an alarm in the event of an unauthorized opening or removal attempt. Configuration and inclusion in the system is simple thanks to compatibility with the Dahua AirShield control panel and firmware updates can be performed remotely via the cloud.

This detector is suitable for residential or professional environments where discreet and reliable monitoring is required to detect any intrusion or unauthorized movement.
