The Dahua DHI-ARD512-W2 is a wireless glass break detector designed to enhance security by detecting various types of glass breakage, including tempered, laminated, and double-glazed glass. It utilizes advanced sound detection technology, simultaneously monitoring high and low-frequency sounds to minimize false alarms. This device features a two-channel alarm input, allowing for enhanced flexibility in security configurations. A key benefit is its ability to perform cloud updates and automatically recover from any update failures, ensuring optimal functionality. Additionally, the detector employs a two-way encrypted communication system to bolster security and stability during operation. It includes a wireless frequency hopping mechanism that switches frequencies automatically when interference occurs, maintaining reliable communication. The detection range extends up to 9 meters, making it suitable for various indoor environments. The DHI-ARD512-W2 operates on a CR123A battery, with an impressive battery life of up to three years under normal conditions.
