Please note:
You can mount the glass breaking sensor V2 on a wall or on a ceiling.
The glass breaking sensor V2 triggers an alarm if it detects a hit on the window
and, then, the breaking of glass.
The glass breaking sensor V2 has a detection radius of 360° by means of acoustics
and sound pressure.
Make sure that no obstacles are between the window and the glass breaking
sensor V2.
Install the glass breaking sensor V2 in an open space (not in corners), in order
that sound waves can reach the sensor from as many sides as possible.
Do not install the glass breaking sensor V2 close to other electric devices (e.g.
loudspeakers, ACs, or other devices that can emit sounds).
The first generation of glass breaking sensors V2 used the ZigBee protocol and
requires a ZigBee repeater to enhance the signal strength.
All newer generations use 868MHz and require a wireless repeater to enhance the
signal strength. You can see the used frequency directly on the glass breaking
sensor V2:
