Ajax DoorProtect


The Ajax CombiProtect has a motion detector and a glass break detector. It detects motion in the room at a distance of up to 12m and registers broken glass at a distance of up to 9m.

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.

The sensor comes with a battery and is therefore ready for installation. Scan the QR code on the back of the device with your smartphone and it connects to the hub. It can be mounted to the wall on the SmartBracket in just a few minutes.

  • All these units are available in Black and White
