An intrusion detection system (IDS) in physical security refers to a security mechanism designed to detect unauthorized entry into a protected area or facility. It works by monitoring the environment for signs of intrusion, such as motion, heat, or sound.
Physical IDS typically consist of sensors, control panels, and alarms. The sensors can be mounted on doors, windows, or walls, and they detect changes in the environment such as motion or sound. The control panel processes the data from the sensors and triggers an alarm if an intrusion is detected.
There are several types of physical IDS, including:
- Perimeter intrusion detection systems (PIDS): These systems monitor the outer perimeter of a facility or area and are designed to detect intruders before they can gain access.
- Interior intrusion detection systems (IIDS): These systems are designed to detect intruders after they have breached the outer perimeter and entered the interior of a facility or area.
- Point intrusion detection systems (PIIDS): These systems are designed to protect specific points of entry, such as doors or windows, and detect when they have been breached.
Overall, physical IDS is an essential component of physical security and helps to protect people, property, and assets from unauthorized access or intrusion.
