Describe Different Types of Sensors to Detect Intrusions

Question

Examlex · Accepted Answer

The Answer is There are a number of different types of sensors: motion detectors, thermal detectors, glass breakage detectors, weight sensors, and contact sensors. Motion detectors detect movement within a confined space and are either active or passive. Thermal detectors work by detecting rates of change in the ambient temperature of a room. Contact and weight sensors work when two contacts are connected-for example, when a foot steps on a pressure-sensitive pad under a rug, or a window being opened triggers a pin and spring sensor. Vibration sensors also fall into this category, except that they detect movement of the sensor rather than movement in the environment.
