Ajax GlassProtect


The Ajax GlassProtect is a small wireless detector that notifies the Ajax Hub when glass is broken. A microphone in the device registers the sound of glass breaking and/or glass falling.

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