Ajax CombiProtect - Motion and Glass Break Detector - White

The Ajax CombiProtect White for advanced indoor perimeter and volumetric defense

The Ajax CombiProtect White sets a new benchmark in electronic security, centralizing two vital detection functions into a single compact device. By merging a passive infrared (PIR) volumetric sensor and a high-fidelity acoustic microphone, this hardware simultaneously safeguards against unauthorized human intrusion and the physical destruction of glass surfaces. Its premium matte white finish ensures a discrete architectural integration, minimizing aesthetic impact on ceilings and walls while reducing implementation costs.

Digital thermal analysis and certified pet immunity

Volumetric detection within the Ajax CombiProtect White relies on a pyroelectric sensor complemented by the advanced SmartDetect digital algorithm. This wireless ajax system performs real-time temperature compensation, analyzing the environment's infrared radiation profiles to isolate human heat signatures. This innovative technology guarantees reliable pet immunity for domestic animals weighing up to 20 kg and under 50 cm in height. The built-in software actively assesses the thermal signature of the incoming signal, preventing false alarms.

Advanced acoustic glassbreak detection using DualTone validation

For the proactive security of storefronts and windows, the integrated electret microphone continuously monitors the acoustic spectrum using a specialized two-frequency validation process (DualTone technology). An alarm event is generated only when the equipment sequentially registers the low-frequency impact (the physical shockwave hitting the glass pane) followed instantly by the high-frequency crunch (the unique acoustic signature of breaking shards). This architecture prevents everyday ambient noises from causing accidental triggers in the ajax system.

Jeweller wireless radio protocol and built-in anti-sabotage features

Integration within the wider security setup is performed through the proprietary Jeweller radio protocol, operating with permanent two-way AES block encryption across the 868.0 – 868.6 MHz frequency bands. This protocol guarantees stable data transmissions up to a distance of 1200 meters in open field line of sight and implements automatic frequency hopping during interference scenarios. The physical housing features Grade 2 certification, integrating a highly sensitive mechanical tamper button.

Simplified professional installation and system links

Engineered for professional system integrators, the device is paired with the main control panel in a matter of seconds by scanning the printed QR code via the official smartphone app. Mounting is cleanly executed using the included SmartBracket installation panel at the ideal recommended height of 2.4 meters.
