3.2 Glass Break Detection

For reliable glass break detection in building automation, various sensor-based methods can be used to identify the unique signals associated with glass breakage. By combining sound and vibration detection, or using advanced frequency filtering, these methods help make sure accurate, responsive monitoring with minimal false alarms. Common approaches include using piezo sensors to detect impact vibrations, microphones for audio pattern recognition, and even accelerometers for multi-axis vibration sensing. Each method offers unique advantages and can be tailored to be designed for the specific security needs and power constraints of automated building systems.
