Glass break detectors are designed to detect a glass break detector functions. When an intruder trying to break the glass of crime, it can send out a warning signal. Accordance with the principle of different manufacturers of glass break detectors, glass break detectors can be divided into two categories. One is a voice-based single technical glass detectors. The other is the dual technology glass break detectors. Which it is divided into two: one is the voice type vibration type combined with dual technology glass break detectors, the other is the simultaneous detection of infrasound and glass breaking high frequency sound of dual technology glass break detectors. General buildings, generally its various rooms in the house is through the interior doors, windows, Walls, floors, ceilings and other objects and outdoor environments separated from each other, which resulted in the room internal and external environment, temperature, temperature , pressure, air flow and other aspects there are some differences. Especially for those doors and windows closed, closed with good room, indoor and outdoor environmental differences that it would be greater. When an intruder tries to enter room when committing the crime, you must choose to open a channel in a position of this room. Such as broken glass, forced into the room, or in the walls, ceiling skylight, drilling a hole on the door glass break detectors supply, to open a gap, or forced open the doors and windows to enter the room. Thanks to the aforementioned pressure due to the different indoor and outdoor environments caused by poor air flow, resulting in an air gap or passage open disturbed at the glass break detectors companies, resulting in some liquidity. Furthermore, when the door was forced open window, due to a certain acceleration, causing air to be squeezed will further deepen this disturbance.
