Dahua AirShield Wireless Glass Break Detector ARD512-W2

The Dahua ARD512-W2 is a critical perimeter security component of the AirShield line. This advanced detector uses a high-sensitivity omnidirectional microphone and digital processing to accurately identify the breakage of multiple glass types, including tempered, laminated, double-glazed, and float glass (thicknesses from 2.4mm to 6.4mm). Its dual-frequency intelligence simultaneously analyzes impact sounds (low frequency) and shattering sounds (high frequency), effectively eliminating false alarms caused by common household noises.

With a detection range of up to 9 meters, the ARD512-W2 stands out for its versatility by including two auxiliary alarm inputs (NO/NC). These ports allow you to convert third-party wired sensors into wireless devices, integrating them into the AirShield system. Thanks to the 868MHz two-way communication protocol with AES128 encryption and frequency hopping, this detector offers an ultra-stable and secure connection, with a battery life of up to 3 years and full management via the DMSS App.
