Intrusion detection panels, keypads, and modules form the core components of an intrusion detection system. Control panels serve as the central processing unit, receiving signals from sensors and managing the system's responses to potential breaches. Keypads provide a user interface for arming, disarming, and programming the system, allowing authorized personnel to monitor and control security operations. Modules extend system functionality by adding features like remote monitoring, communication with external networks, or integrating additional sensors. Together, these components coordinate the detection and alerting processes, ensuring comprehensive security management, quick response to unauthorized access, and seamless integration with other safety systems.
