Ajax GlassProtect

Ready to operate straight out the box

Ajax MotionProtect Curtain comes with pre-installed battery so you do not need to disassemble it. The detector can be connected to the hub with one click in the mobile application.

Principle of operation

Detects broken glass using an electret microphone, which registers the sound of impact against the glass and of the glass falling.

The GlassProtect detects breakage up to a distance of 9 m and filters events that cause false alarms such as thunder, dogs barking and noise from passing trucks.


Two-factor detection of broken glass prevents false alarms caused by thunder, dogs barking and noise from passing trucks.
