Monitor glass windows and doors for break-in attempts with the Ring Alarm Glass Break Sensor. Using AI technology, the sensor detects the sound of glass breaking up to 25 feet. Get mobile alerts when the Glass Break Sensor detects the sound of glass shattering in your home, or set the sensor to automatically sound your Ring Alarm siren when armed in Home or Away mode. It can be mounted to your wall or ceiling, or be placed on furniture. You can also connect your Ring Doorbells or Ring Cameras and set them to start recording when the glass break sensor triggers your Ring Alarm siren.
