Outline
Glass break detectors are designed to detect a glass break detector function. When the intruder shattered the glass trying to commit crimes , They can send alarm signal. It is the fruit of high-tech digital technology, it is the microphone receives the audio signal is filtered by a digital microprocessor and accurate analysis, more memory database, broken glass, and the actual signal (4-6Khz) compared to the waveform of the neglecting other noise, to determine whether the alarm signal, it can accurately detect the true voice of broken glass, and other noise (eg, clap) will not cause false positives. Since the detector is the signal waveform analysis rather than the amplitude, then it can penetrate the shielding curtain and other monitoring, and will not change the installation environment (such as the head of the household add curtains or furniture) and impact monitoring quality. While its adjustable sensi
