Glass break sensors or Audi Discriminators have been around for a
number of years. The technology has advanced in recent years and there
are now a number of different versions available. The basic concept of
a glass break sensor is to detect and sound an alarm if there is a
sound of breaking glass. The original concept was based around a single
technology wh
ich only picked up on the sound of breaking glass, however
today there are now dual frequency devices which will not only pickup
on the sound of breaking glass but also on the splintering of wood.
Most of the glass break sensors today will use the dual frequency
technology.
The technology works by
listening at the frequency that glass breaks and if this sound is
detected then the alarm is activated. There are some points that need
to be made clear before you decide on this form of security, firstly
the technology does not work through walls, ceilings or doors. With
this in mind you would need to have a sensor in each of the rooms where
you have glass windows or doors. This can be a costly exercise to have
sensors in all of these places and you may not wish to have this many
around the house in every room.
