Approved installers for AJAX alarm products

CombiProtect is a device combining a wireless motion detector with the viewing angle of 88.5° and distance up to 12 meters, as well as a glass break detector with the distance up to 9 meters.
It can ignore animals and detects a person within the protected zone from the first step. 

Principle of operation

CombiProtect combines two types of security devices – motion detector and glass break detector.

Thermal PIR sensor detects intrusion into a protected room by detecting moving objects with a temperature close to the temperature of the human body. However, the detector can ignore domestic animals if the suitable sensitivity has been chosen in the settings.

The electret microphone is responsible for glass break detection. The intelligent event registration system requires a sequence of sounds of a specific nature – first dull blow, then ringing sound of falling chips, which prevents accidental actuation.

After actuation, the armed detector immediately transmits an alarm signal to the hub, activating the sirens and notifying the user and security company.

If before arming the system, the detector has detected motion, it will not arm immediately, but during the next inquiry by the hub.


The device automatically increases or decreases the sensor sensitivity in order to accurately detect motion during hot and cold weather.
  • Operates up to 5 years without battery replacement
  • Ignores cats and dogs with weight of up to 20 kg and height up to 50 cm
  • Detects motion at a distance of up to 12 m and breakage at up to 9 m

The device detects motion even in hot climates by means of temperature compensation. It filters false alarms caused by thunder, dogs barking or the sound of passing trucks.
