Intrusion Detection Level I Practice Exam

Question: 1 / 400

What is a common application of acoustic sensors in security systems?

To secure doors

To monitor smoke levels

To detect broken glass

Acoustic sensors are specifically designed to detect sound waves, which makes them particularly effective in identifying specific sounds associated with security breaches. The detection of broken glass is a prime application for these sensors. When a window shatters, it produces a distinct sound frequency that acoustic sensors can pick up. By recognizing this sound pattern, the system can trigger alerts and take appropriate action, such as notifying security personnel or activating alarms.

In contrast, while other options may involve sound in some capacity, they do not utilize acoustic sensors directly for their primary functions. Securing doors typically relies on mechanisms like locks and alarms, monitoring smoke levels involves smoke detectors that sense particulate matter, and tracking movements in dark areas generally employs motion sensors or infrared technology rather than acoustic-based detection. Thus, the use of acoustic sensors for detecting broken glass is both a practical application and a clear demonstration of how they contribute to enhancing security systems.
