Lesson 7_The priciple of glass sensor

There is a Piezoelectric Ceramic Sensor in the audio glass break detector, which can detect the audio of the hard object hitting the glass, and it doesn’t affect by window vibration, hand and foot hitting, wireless interference, etc. No need to make sensitivity adjustment, it is suitable for the protection of any kind of glass (installation surface needs to be flat). The detector has tamper-evident feature, and detectable warning range is 180cm in radius. The door and window glass is suitable to install in general.
**Installation with magnetic reed switch could be safer**
The audio glass break detector is mainly used with a magnetic reed switch to prevent direct intrusion of windows. Use Sengate glass sensor to prevent the intruders!!
