Dahua DHI-ARD512-W2 (868) V - Wireless Glass Break Detector

Dahua DHI-ARD512-W2 (868) Wireless Glass Break Detector

The Dahua DHI-ARD512-W2 (868) detector is a wireless glass break detector designed to be integrated into a Dahua alarm system operating on the 868 MHz frequency. It is specially designed to monitor and detect the breakage of a glass surface, such as a window, bay window, veranda or shop window, and immediately transmit an alert to the alarm centre.

The detector uses advanced acoustic technology capable of identifying the characteristic sounds of glass breaking, analyzing both the high and low frequencies emitted during the break. This method makes it possible to distinguish true breakage events from common ambient noises, thus reducing the risk of false alarms. It is designed to provide reliable and responsive detection in residential or professional environments.

This device is intended for indoor installation, generally fixed close to the glass surface to be protected in order to optimize the reception of sounds and vibrations. It communicates with the alarm panel via a secure 868 MHz two-way radio link, using encryption and frequency hopping techniques to ensure stable, secure, and interference-resistant transmissions.

The detector is battery-operated, which allows it to operate without direct electrical wiring, offering flexibility and simplicity of installation. It also incorporates an anti-tamper contact that triggers an alarm if the enclosure is opened or tampered with without authorization. An LED indicator provides visual feedback on the status of the detector, making commissioning and diagnostics easier.

This glass breakage detector is suitable for environments requiring targeted protection of glazing, such as homes, commercial premises or offices with large glass surfaces, providing an effective security complement to other motion or opening sensors. It allows a specialized detection layer to be added to the Dahua alarm system for more comprehensive protection against break-ins.
