Which type of detector is specifically designed to monitor glass breakage?

A glass break detector is specifically designed to monitor glass breakage, making it the correct choice for this question. These detectors utilize specialized sensors to detect the specific sound frequencies and shock waves generated when glass shatters. This capability allows them to differentiate between the sounds of glass breaking and other ambient noises, ensuring reliable alerts in the event of an intrusion.

In contrast, other types of detectors serve different functions. For instance, heat detectors monitor temperature changes in an environment to identify fire hazards, but they do not monitor glass or specific breakage events. Magnetic contacts are generally used on doors and windows to sense when they are opened or closed, offering no functionality for detecting glass breakage. Similarly, perimeter detectors may include various forms of technology for monitoring the outer boundary of a security zone but are not specifically tailored for glass break detection. Thus, the glass break detector stands out as the specialized tool for this particular application.
