Which is not a basic component of an intrusion detection system?

An intrusion detection system (IDS) is primarily designed to detect unauthorized access or breaches in security, typically within a network or physical premises. The basic components of an IDS generally include sensors that monitor various activities and systems, and a control panel that manages and processes the information from those sensors.

Entry door cameras, while valuable for monitoring physical spaces, do not typically fall under the purview of an IDS. Instead, the other components listed — motion sensors, alarm control panels, and glass break detectors — are integral to the detection and alerting functions of an IDS. Motion sensors detect movement within a designated area, alarm control panels manage and process inputs from various sensors, and glass break detectors specifically sense the sound or vibration of breaking glass, all of which contribute directly to intrusion detection capabilities.

Thus, identifying entry door cameras as not being a basic component of an intrusion detection system is correct because they serve more as a surveillance tool rather than a primary detection mechanism within the context of an IDS.
