Contact sensors only know when a window opens. This one hears it break, picking up both the thud of the impact and the shatter that follows, within 25 feet in any direction.
In the box & care
In the box: glass break sensor, CR123A battery, adhesive strips, screws, quick-start guide.
Care: mount on a wall or shelf with a clear line to the windows. Test from the app with a hand clap.

One sensor for the whole lounge
We have five windows in the living room and this covers all of them. The clap test in the app confirmed it hears from every corner.
