Glassbreak Sensors
Acoustic Glassbreak sensors, usually mounted on ceilings or walls,
work by "listening" for the sound of breaking glass in a window.  
"Shock" glassbreak detectors are mounted on the window and "feel"
the shock of breaking glass. This kind of advanced wireless technology
can provide shatter and shock protection for your windows, for often
intruders are "sensed" and an alarm sounded while they are still
outdoors. This is often enough to send a burglar running!
