Perimeter Intruder Detection

Perimeter Intrusion Detection Systems (PIDS) is a generic term which covers a wide range of technologies designed to provide advance warning of an intruder gaining access to a secure area.

Last Updated 10 November 2020


Perimeter Intruder Detection Systems (PIDS) act as a technology force multiplier, they keep a constant watch on a site’s perimeter and offer the opportunity for early detection of an attack.

PIDS systems are normally designed to work in a specific scenario, CPNI assure PIDS into the following categories.

Barrier-mounted PIDS

Barrier-mounted PIDS can be divided into two further categories:

Fabric mounted systems, where the sensor is attached to the fabric of a fence and post mounted systems, where sensors stretch between either fence posts or dedicated posts.

Ground-based PIDS

Ground-based PIDS are buried in the ground and may or may not be deployed alongside a fence.

Free-standing PIDS

Free-standing PIDS cover an area above ground and may or may not be deployed alongside a fence.

Wide-area detection systems

Unlike free-standing PIDS which are designed to detect intrusion along a perimeter, wide-area detection systems cover a large area within and external to a site perimeter, allowing for detection and tracking within an open space.

Rapidly-deployable detection systems

Rapidly deployable detection systems can operate using any of the above detection methods.  A rapidly deployable system is defined as one which can be deployed by two people within a short period of time.

Rapidly-deployable systems should not be used for more than a two week period without the system being re-commissioned.

Hatch Detection Systems (HDS)

HDS are used in an external environment to detect an intrusion or attempted intrusion through the fabric or opening of a hatch.
