Single device. Dual protection
We have combined the functions of our two detectors and created a universal security solution for different types of objects — CombiProtect Jeweller. The device features software algorithms to prevent false alarms and has two primary functions — motion detection and glass break detection. Both sensors can be remotely configured in the app, as well as the required sensitivity level. It is also possible to test the device via the app. The intuitive interface and hassle-free installation create a satisfying PRO and end-user experience.

Enhanced glass break detection
CombiProtect 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.

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 is easily replaceable, allowing one to swap them out after approximately five years of autonomous operation. The battery status is always accessible via the Ajax app. Users and security companies receive low battery level warnings months in advance, allowing for timely replacement without rushing.

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.

System supervision
All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, such as a tamper state, communication, power supply, and sensor statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for ARCs, security companies, and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.

Effortless installation and setup
CombiProtect Jeweller is ready to operate straight out of the box. Using the SmartBracket panel, an installer can effortlessly mount the device on the wall, eliminating the need to disassemble the enclosure. Ajax apps help quickly make the device a part of the ecosystem: simply pair the device with the hub by scanning the QR code. It can always be reconfigured remotely without the need for on-site visits.
