What type of alarm could an intrusion detection system generate?

An intrusion detection system (IDS) is designed to monitor and analyze activities within a specific area to detect unauthorized access or anomalies. The type of alarm that such systems generate plays a crucial role in alerting personnel to potential security breaches. Local or paging alarms are effective because they provide immediate notification to security teams or individuals who need to respond swiftly to unauthorized access. This direct communication is essential for minimizing the potential impact of an intrusion.

Local alarms might include audible alerts at the site of the intrusion, while paging alarms can send messages directly to personnel, allowing for a coordinated and timely response no matter their location. This feature is crucial for maintaining security in real-time, ensuring that intrusions are addressed quickly.

Environmental alerts, power failure notifications, and temperature change alerts, while important in different contexts, do not specifically relate to the primary function of an intrusion detection system. The focus of an IDS is on detecting and alerting about security breaches, hence the emphasis on local or paging alarms.
