The Wireless Glass Break Detector recognizes when different types of glass are breaking, triggering alarms in real time. With its advanced technology, it picks up the low-frequency and high-frequency that glass breaks at, reducing the occurrence of false alarms caused by noise interference from the environment. It also comes with 2 external ports that can connect to third-party wired detectors. When placed in a home or building, it helps protect families and work places from intrusions.
