Time profile of the glass-break detector testing scenario based on the accelerometer

Abstract

This paper is focused on the contact glass-break detectors used in technical security namely in the Intruder Alarm Systems. The glass-break detector is used as the main component of the perimeter layer of protection against the potential intruder. The main aim of this research is to measure and calculate the average time duration of the impact on the glass panel. More specifically, how long does it take to absorb created vibrations by the glass panel and the window frame. This number can also determine the maximal possible detection in one second. The second outcome is the graphical representation of the impact itself in time. The main experiment is done according to the standardization for the contact glass-break detectors and it is done by using the accelerometer placed on the glass panel which measures vibrations created by the impact in real-time. These data are measured and evaluated by the development of the development board called Arduino Nano, and the accelerometer MPU-6050. The experiment comes with all needed explanations and technical documentation. © 2022 IEEE.
