Focusing on systems designed to detect unauthorized entry or activities, intrusion detection is vital for security in various settings. It includes sensors, alarms, and control panels that monitor spaces for signs of unauthorized access or break-ins. These systems are integral to comprehensive security strategies, offering protection against theft, vandalism, and other security breaches. By alerting personnel or law enforcement to potential threats, intrusion detection systems play a crucial role in safeguarding people, property, and sensitive information.
