What does PIDS Stand For? PIDS security explained

The acronym PIDS, which stands for Perimeter Intrusion Detection System, is commonly used in the security industry. It’s used to describe cutting-edge security devices that emphasise the early detection of attempted intrusions as a means of preemptive defence.

A PIDS is designed to meet any risk that surrounds a property or site perimeter. Whether your system is ground-based, freestanding or barrier-mounted, having a PIDS on your property lessens the possibility of an incursion by sounding the alert as soon as possible.

A strong perimeter intrusion detection system is implemented to give a better level of protection, especially when boundaries are hard to maintain, dispersed over large areas, or where there is a larger chance of criminal activity. 

How do PIDS work? 

The core function of PIDS is to use advanced technology to identify breaches and attempted incursions. However, PIDS also ensure reliable functionality by preventing false alarms caused by non-threats like animals, the weather, or natural events such as falling branches.

Typical PIDS characteristics include: 

Gate-mounted/electric fences

The intelligent danger detection and continuous monitoring of gate-mounted PIDS help prevent false alarms. When pressure or unauthorised movement suggests that there may have been an incursion or criminal conduct, they become active.

Wall-mounted systems

Motion-detecting PIDs put on walls are designed to detect any attempts by intruders to scale fences or walls or to position climbing apparatuses like ropes or ladders up against walls.

The vibrations are detected by sensors that are calibrated to distinguish between a genuine threat and a false alert.

Ground-based PIDS

Freestanding or ground-based PIDs are perfect for properties without a clearly defined perimeter, such as a fence or boundary line.

They can be freestanding or buried underground, protecting designated zones when deployed over larger regions. In restricted access locations, systems detect footfall to notify responders of any movement.

Each PIDS has a different set of features and functionalities depending on the topography, points of entry, major risk assessment results, and other on-site security protocols, facilities, or equipment.

However, because PIDS are technical devices, they are ideal for locations where any potential intrusion needs to be handled quickly and efficiently.

How are PIDS used strategically?

All sites, buildings, compounds, and properties are unique. In order to identify threats, assign severity ratings, and choose the best PIDS, a thorough risk assessment is the first step.

Working closely with clients, our consultants assess variables like:

  • Regions or ports of access that are most likely to be the focus of an attempted or unauthorised trespass.
  • Determining the optimal locations for security assets by mapping the topography, surrounding area, and hotspots.
  • Defining current security measures and determining when it is most appropriate to strengthen them, taking into account elements like gates, walls, fences, and barriers.
  • Considering visibility: should the PIDS be a hidden surveillance system that is not apparent to unauthorised visits, or should it be a very visible preventive measure with signage to discourage potential intruders?
  • Measurements of the perimeter, lines of sight, and signalling choices to guarantee that alerts are conveyed safely via tamper-proof networks or are audible.
  • Existing site usage, times when footfall, vehicles or other activities are beyond the scope of usual activity, and how PIDS must operate to prevent disrupting routine foot traffic.
  • The site’s existing communication infrastructure and whether it can be used to incorporate a sophisticated PIDS or whether new communications technologies are needed.

 

To assist you in identifying and assessing all the major risks that need to be addressed, our knowledgeable security advisors can guide you through the risk assessment process and provide unbiased advice.

What are the different types of PIDS?

We’ve discussed the various configurations, uses, and styles for PIDS systems. However, there are even more choices within each PIDS category that are crucial to understand.

1. Mounted PIDS

If criminals use tools to climb the physical barrier, a fence painted with anti-climb paint may be useful, but it is not always so.

That’s why a barrier-mounted PIDS can increase the level of protection provided and is fastened to already-existing obstacles.

Integrated technologies for fence PIDS include:

  • The vibration-detection cable systems in mounted PIDS use microphonic frequencies to distinguish between wind-generated vibrations and wildlife-generated vibrations. They can identify odd behaviour and notify responders or security teams.
  • Low-frequency point sensors and geophones are mounted to walls, gates, or other fencing structures in order to detect vibrations and instantly sound an alarm.
  • Electric fencing is made of horizontally positioned, electrified wires with harmless charges that repel intruders and sound an alert in the event that the cable is severed or the voltage is earthed. When cables or wires come into contact with a fence, earthing might happen as a result of force or tampering.

 

Mounted PIDS can often improve an existing gate or fence; however, walls or fences that are too light or have inadequate foundations may require reinforcement. 

2. Ground-level PIDS

PIDS at ground level may be hidden beneath the earth or as a prominent deterrent.

They can be installed throughout a compound of open land areas between a border and a premise or property, or they can be placed inside the fence line to guard the perimeter. The variety of available gadgets and sensors is also wide:

  • Fluid tubes work on a basic principle: if the pressure inside the tube becomes noticeable enough to reveal the presence of a person or vehicle, the gadget reports the event and possibility of an entry.
  • The main idea behind fluid tubes is that if the pressure inside the tube becomes apparent enough to indicate the presence of a person or vehicle, the device will report the incident and the probability of an entry.
  • By using radio frequencies to detect changes in the air, leaky feeder cables create electromagnetic fields that notify security monitoring teams and emergency personnel to the presence of an intruder passing through the area.

 

Ground-based PIDS are suitable for a variety of applications, including high-security locations like transportation hubs, corporate buildings and laboratories, or production and manufacturing centres where entry into a restricted area is not authorised by law. 

However, they can be among the more expensive options.

3. Freestanding PIDS

A standalone PID is the last choice; it can be installed in any area of concern and includes the following features:

  • Using a transmitter and receiver, infrared motion detection uses technology to detect and identify intruders.
  • In a protected zone, movements are detected via radio wave monostatic or bistatic devices.
  • By measuring body temperature, passive infrared sensors can identify human movement in regions that are restricted.

 

Given the variety of configurable detection solutions and rapid deployment systems that are available, PIDS are among the best options in a wide range of situations.
