Pictured below 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. There are many different
models of both shock sensors and glass break detectors..Though there
are many different kinds of glass break detectors and shock sensors.
Glass Protection:
Shock sensors and glass break detectors both protect glass however
they operate on different principles.

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,
random animals and human activity, as well as other sources to include
electronic interference. One good example would be the passing of a car
with a loud stereo system. We all have felt the tremendous vibrations
of some of these stereo systems as they drive by. The sub woofers can
vibrate glass and cause a shock sensor to go into an alarm condition.
Pets, especially dogs have a tendency to paw at windows and this can cause
a false alarm condition Dogs have been known to trip shock sensors just
by barking. Shock sensors are usually installed in high risk areas where
entry into protection points 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.
