Which component is NOT included in an intrusion alarm system?

The component that is not included in an intrusion alarm system is the video surveillance camera. An intrusion alarm system primarily focuses on detecting unauthorized access or breaches within a physical space. This detection is typically carried out by interior detection devices, such as motion sensors or door/window contacts, which trigger alerts when they sense activity. The system also includes a keypad for user interaction, allowing individuals to arm or disarm the system, and an audible signaling system to alert occupants and deter intruders during an alarm event.

While video surveillance cameras play a crucial role in security by monitoring and recording activities, they are classified as a part of video surveillance systems rather than intrusion alarm systems. The primary function of an intrusion alarm system is to create immediate alerts to breaches, which surveillance cameras do not provide by themselves—they can complement an alarm system but are not essential to its core function.
