Accelerometer-based glass-break detector for alarm applications

Abstract

The aim of this paper is to introduce and improve the functionality and reliability of the indoor glass-break detectors for the security application. The most vulnerable part of the house security are the windows which are fragile and very easy to overcome. The glass-break or shock detector are generally used to detect the potential intruder by vibration which is spreading through the glass. The alarm is triggered when a threshold level of the vibration is exceeded. However, the further information of the intrusion is missing. The goal of this paper is a design of a glass-break detector based on the accelerometer which can also detect the vibration in the glass panels with higher accuracy. The main advantage of the implemented accelerometer is the ability to sense several influences of the environment. The program can reliably distinguish between main influences like the rain, storm or strong wind. This function can also be used for the non-alarm application. However, the main function is still focused on the security application. The designed detector should be able to communicate with commercially made Control and Indicating Equipment via the wired connection.

Development of a Contact Glass-Break Detector for the Highest Security Level

“…A thorough search of prestigious peer-reviewed articles was conducted, and it can be concluded that there has not yet been developed any contact glass-break detection system for glass panes that would meet the highest security level. In our previous studies [ 22 , 23 ], we proposed a new concept of a contact glass-break detector that is physically placed directly on the glass pane and based on an accelerometer, thus being intended to be more sensitive to emerging vibrations. Therefore, the main objective of this research is to develop and verify a contact glass-break detection system that would meet the highest security level requirements according to the European standard EN 50131-2-7-2 [ 15 ], as amended.…”
