Now 433Mhz wireless glass break detectors are availabile
Recently months, many customers are requesting for the wireless glass break sensor, but we could not provide it to our customers.
In this year, now we can providing Wireless Glass Break Sensor to our customers.
Firstly, we check out what's the glass break sensor ?
Answer (From Wiki): A glass break detector is a sensor used in electronic burglar alarms that detects if a pane of glass is shattered or broken. These sensors are commonly used near glass doors or glass store-front windows to detect if an intruder broke the glass and entered.
Glass break detectors usually use a microphone, which monitors any noise or vibrations coming from the glass. If the vibrations exceed a certain threshold (that is sometimes user selectable) they are analyzed by detector circuitry. Simpler detectors simply use narrowband microphones tuned to frequencies typical of glass shattering, and react to sound above certain threshold, whereas more complex designs compare the sound analysis to one or more glass-break profiles using signal transforms similar to DCT and FFT and react if both the amplitude threshold and statistically expressed similarity threshold are breached.
Introduction:
GlassTrek delivers effective coverage of plate, tempered, and laminated glass without the need for complicated sensitivity adjustments. GlassTrek can be used in most protected areas, including rooms with blinds, curtains, or multiple windows as long as careful coverage tests are conducted using TestTrek. Breakage in panes of glass 40.6cm x 61cm (16in x 24in) or larger will be detected, for every standard thickness of plate (0.3cm x 0.6cm or 1/8in-1/4in).
