Which type of sensors are used to detect the breaking of glass?

Glass break sensors are specifically designed to detect the sound or vibrations produced when glass is broken. These sensors can distinguish the unique frequency of breaking glass through acoustic recognition or vibration sensing technologies. This makes them particularly effective in security systems for protecting windows and glass doors in commercial or residential settings.

Unlike magnetic sensors, which are primarily used to detect the opening of doors and windows by monitoring the position of magnets, glass break sensors are tailored to respond to the specific event of glass breaking. Infrared sensors detect changes in infrared light, usually from body heat, which makes them suitable for motion detection but not for listening to the sound of glass breaking. Similarly, motion sensors are designed to detect movement within a given area and are not specialized for glass breakage. Therefore, glass break sensors are essential for providing targeted protection against glass-related intrusions.
