Glass breakage sensors and window sensors help detect break-ins.
In terms of home security, both glass breakage and window sensors are used to monitor the safety and condition of your windows, a prime area of entrance by a would-be burglar. One sensor relies on sound to trigger an alarm, while the other registers an unauthorized window opening.
Design
Glass breakage sensors monitor the area for the sound of shattering glass and splintering wood. Window sensors are two-part devices that attach to the window itself and the frame, sounding an alarm when the window is opened.
Types
Both types of sensors are available in wireless configurations, or can be wired in to your home's alarm system and will trigger the house alarm if set off.
Placement
A glass breakage sensors can be mounted on the wall or ceiling and monitor all windows within its direct path --- it cannot "hear" around corners or through doors. A window sensor must be mounted on or very close to the window it's intended to monitor.
Range
All windows within a 35-foot radius can be monitored by a single glass breakage sensor, so long as there are no doors, walls or other objects to block the sound. Window sensors are only capable of monitoring one window per device.
