In an intrusion detection system, sensors and contacts serve as the primary mechanisms for identifying unauthorized entry. These devices work by monitoring physical access points, such as doors and windows, and detecting when they are opened or tampered with. For instance, door/window contacts consist of two parts: one attached to the door (or window) and the other to the frame. When the door or window is closed, the two parts align, and the system registers this state. If the door or window is opened, the alignment is broken, which triggers the system to alert security personnel or the monitoring center.

Sensors can include motion detectors or glass break sensors, which provide additional layers of protection by identifying movements within a secured area or detecting the sound of breaking glass. Together, these devices create a robust detection mechanism that is essential for effective intrusion detection.

The other options, such as deterrent systems, smart locks, and access control panels, play significant roles in security but do not focus primarily on detecting unauthorized entry. Deterrent systems discourage intruders but do not necessarily provide alerts; smart locks enhance access control but are not primarily for detection; and access control panels manage entry permissions rather than detect intrusions. Thus, sensors and contacts are the most relevant to the question
