Glass Break Detectors

Pictured above on the right is a shock sensor. On the left is a glass break detector. They both are glass protection devices. A shock sensor goes into an alarm condition when the glass that its attached to is hit with a significant amount of force. A glass break detector goes into alarm when the frequency of breaking glass is detected.

Devices such as glass break detectors and shock sensors are considered exterior protection points.   Glass break detectors and shock sensors have have  a higher probability of generating false alarms

This is due largely to many uncontrollable factors such as: wind, rain, thunder storms, blowing debris that are weather related.  Other causes can be a loud muffler, a back fire from a passing car, a car stereo system with . large stereo speakers with subwoofers that cause the glass to vibrate, etc.

Pets, especially dogs have a tendency to paw at windows and doors in an attempt to get into the home. Dogs have been known to trip shock sensors just by barking. Shock sensors are usually installed in high risk areas where entry into homes could be through a broken window. It is highly recommended that areas of high risk utilize both glass break detectors and shock sensors as part of the protection package. Utilizing both protection devices would do a lot to reduce the frequency of false alarms. Cross zoning which could require that two zones trip prior to an alarm condition would help tremendously in areas where vibrations are a common occurrence.
