Perimeter Security - Forewarned is Forearmed!

Fact ; traditional perimeter solution with fences, CCTV cameras and sensors no longer keep the really determined people out. A series of incidents at UK international airports has highlighted that traditional reliance upon physical barriers, security patrols and manned monitoring of CCTV is inadequate to counter the threat from a determined intruder. Perimeter security used to demarcate the boundary and secure the assets from theft. It was meant to deter someone getting in, stealing something of value and getting out again - undetected.

The problem, is that the intruder threat of today is of an altogether different magnitude. The intruder(s) are not necessarily concerned about detection and the objective is not to escape without being caught. Rather, the aim is to cause as much damage and disruption on the inside as possible. This level of threat requires a different approach to security and a different level of risk assessment. The only way forward is to look at how we can facilitate an early warning solution which delivers earlier detection and allows more time for the corresponding reaction. This calls for new more sophisticated sensor technology to work in an integrated solution with the existing perimeter solutions already in place.

Fence mounted sensing or buried cable perimeter detection, is effective only to detect and locate an actual breach of the perimeter. In the dark at 2.30 a.m. in the morning, this information is of limited use. The important issue is: how many intruders have entered the property and where are they heading?

The solution, is a wide area situation awareness system; a system that can accurately detect and track the intruders. This is where the AdvanceGuard™ radar technology enters the equation.

Navtech Radar has developed a solution which directs the CCTV cameras to immediately provide visual images of whatever incident has been flagged up. At the heart of the system is a high frequency, low power, radar. Based upon the same radar technology as automotive active cruise control, the solution is totally safe and non-interfering with other electronic devices.

Some of the advantages of using the AdvanceGuard radar technology in integrated perimeter solutions include

• Radar operates in all weather and light conditions
• Radar scans in 360 degrees continuously 24/7, in 25 cm intervals out to 800 metres
• The control room operator has the flexibility to decide upon detection zones, so only the areas of interest or threat are covered.
• A zone may cover an area outside the perimeter - a radar placed inside the perimeter fence can see through gaps in the fence to detect any approaching potential intruders.
• When an incident is taking place, the radar will detect and track any person or vehicle moving in its detection zones and then automatically control associated CCTV cameras to follow the intruder and produce a visual image.
• Unlike other systems, the radar has the capability to track multiple intruders, as one radar can control up to five independent CCTV cameras.
• The solution can be retrofitted

The control room system display is an aerial map of the site where intruder tracks are shown in real time with accurate location, direction and speed of each intruder together with a real time CCTV image of the incident. This enables fast direction of manned patrols to where a breach is in process. No longer can the operator be accused of being at fault for not concentrating and never again will it be the case that the camera was pointed in the wrong direction to capture the incident.
