Glass Break Detector Simple That is to say, it is a sensor that detects broken glass and triggers an alarm when it senses that the glass is broken.
Glass breakage detection alarms are suitable for all places that need to warn against glass breakage. In addition to protecting ordinary doors and window glass, it can also act as an anti-theft alarm for large-area glass showcases, showcases, kiosks, etc.
Using the piezoelectric effect of the piezoelectric ceramic sheet (when the piezoelectric ceramic sheet is twisted and deformed under the action of external force, charges will be generated on its surface) to make a glass breakage intrusion detector. It effectively detects high-frequency glass breaking sounds (~) and has a strong suppression effect on the following sound signals (such as talking and walking sounds). The frequency and intensity of acoustic emission caused by glass breaking are related to the thickness and area of the glass.
1. Application scope
Glass breakage detectors can be effectively applied to flat, strengthened and laminated glass. However, to achieve the best performance of the detector, the glass and supporting fulcrum must be stable. This detector is suitable for glass decorative cabinets, glass doors and windows.
Note: The glass break detector should not be connected to the hour defense zone of the main unit.
2. Functional features
Software-driven microprocessor-controlled digital signal processing.
.High frequency sound pressure detection.
.Full sound spectrum frequency signal and collision analysis including subsound pressure analysis.
.Digital filtering for extremely high RF/EMI interference.
.Unique microphone design.
.Manual adjustment of sensitivity can avoid false alarms.
