DSC Glass Break Detector

 

 

The DSC glassbreak detector is a microprocessor based detector, designed to reliably detect the sounds produced by all
types of framed glass; laminated, plate, tempered and safety glass. The unit uses DSP (‘Dynamic Signal Processing’ –
patent pending) to analyze all sounds and reject those created by all objects that are not breaking glass including
thunder, dogs and all other ‘bell’ or ‘ringing’ type sounds. 

Extensive research was done to identify how a piece of framed glass breaks. When manufactured, all glass contains tiny
imperfections or microcracks that are invisible to the eye. Initially, a piece of glass will bend before it breaks. The
bending of the glass puts pressure on these tiny microcracks and they begin to expand.

When the microcracks begin to join together, the glass breaks. The way in which these microcracks join is random
and causes a large number of different frequencies in the audio spectrum.  A substantial force is required to break
framed glass so the amplitude of these sounds is typically quite high, somewhere in the order of 90 dB at 10 feet.
Finally, the sound will decay very rapidly as the surrounding environment absorbs the noise.
