Manufacturer overview

Wireless glass break detector with a microphone

Intruders can break silence, not security. Forget about the typical problem of glass break detectors — false alarms caused by barking dogs, traffic, water splashing, and extraneous noise. GlassProtect Jeweller has a unique DualTone digital algorithm designed to minimize false alarms. The detectorʼs microphone responds only to vibrations characteristic of the glass breaking sound. You can adjust one of three sensitivity levels and run the test to check if everything works properly.

Enhanced glass break detection. GlassProtect Jeweller uses a sensitive electret microphone and the DualTone digital algorithm to detect the sound of glass breaking. To register a glass break and report an alarm, the device must detect a dull (low-frequency) sound of an impact and a ringing (high-frequency) sound of glass breaking in 1.5 seconds. This two-stage glass break detection algorithm decreases the risk of false alarms. Three sensitivity levels can be configured in the Ajax app, making the detector suitable for any object.

Easy integration with third-party detectors. GlassProtect Jeweller has terminals for connecting a third-party wired NC detector. This allows the installer to enhance system reliability with any NC detector, whether newly installed or already in place, such as motion, opening, or vibration detectors. For example, GlassProtect Jeweller enables you to integrate an existing third-party 2 opening detector into the system.

Wire-free flexibility and reliable performance. Baseline devices operate without any wires, offering maximum flexibility during installation. The pre-installed CR123A battery from proven manufacturers ensures a hassle-free setup, requiring no additional steps to start operating the devices. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the battery characteristics. The battery can be easily replaced after approximately five years of autonomous operation. Its status is always accessible in the Ajax app. Users and security companies receive low battery level notifications months in advance, allowing for timely replacement without rushing.

Unique wireless technology. An Ajax system uses two-way secure radio communication based on the Jeweller proprietary protocol. It provides block encryption and device authentication at each communication session with the hub to prevent sabotage, spoofing, or data theft.

Scaled and comprehensive. ReX 2 Jeweller boosts the radio range of all Ajax devices via Jeweller and ensures stable communication even through steel and concrete via Ethernet using the wire as the additional communication channel. Up to 5 range extenders can operate within one Ajax system to expand the network twice as big, covering underground parking, basement, or metal hangar.
