Lasinsärkyantureita, or glass break detectors, are security devices designed to sense the specific sound frequency produced by breaking glass. These sensors are a critical component of many alarm systems, providing an early warning of potential forced entry through windows or glass doors.

The primary operating principle of a glass break detector relies on acoustic analysis. The sensor contains a microphone and sophisticated circuitry that can differentiate between the sharp, high-frequency sound of breaking glass and ambient noises like conversations, traffic, or other common household sounds. Some advanced models may even analyze the pattern of the sound to further distinguish it from false triggers.

When the sensor detects the characteristic sound signature of breaking glass, it sends a signal to the central alarm panel. This signal then initiates the alarm sequence, which can include sounding a siren, notifying a security monitoring service, or sending alerts to the homeowner's mobile device.

Glass break detectors are typically installed within a room, facing the windows or glass surfaces they are intended to protect. Their effectiveness can depend on factors such as the size and type of glass, the distance of the sensor from the glass, and the presence of any sound-dampening materials. They are often used in conjunction with other types of sensors, such as motion detectors and door/window contacts, to create a comprehensive security system.
