Commercial organisations are increasingly at risk of physical attack as would-be intruders become more sophisticated in their planned assaults. Organisations need to be ready. They need to understand the threats and holistically mitigate the risks.

Sometimes, however, even the most secure perimeter fences and gates experience attacks by potential intruders who will attempt to climb over, or cut through, to gain entry to a secure area, putting infrastructure, assets, property and people at risk. Therefore, being able to reliably detect attacks at the perimeter as early as possible is an essential part of any perimeter security strategy.

According to Heras, one of the UK’s leading experts in perimeter protection, combining the watchful eyes of trained security professionals with technology is the best way to detect suspicious behaviour. Technology such as Electronic Perimeter Intrusion Detection Systems (PIDS) systems  which are used to detect the presence of an intruder attempting to breach a perimeter -  are an ideal solution to mitigate such security risks.

Heras’ new PIDS range - G-fence – which has been designed specifically to provide enhanced perimeter security measures for organisations operating in a range of commercial environments from manufacturing to transportation, logistics, and industrial sites, as well as some critical national infrastructure sites. Importantly, it can be used safely on sites where it is not possible to have an electrical power supply at the perimeter of the fence by working autonomously thanks to power supply from solar panels and batteries that are integrated into each control unit. This ensures continued operation even in low sunshine months or regions.

The G Fence PIDS system is a highly reliable electronic sensor system that detects attacks to the fence via connected sensors installed along the fence monitor which analyse vibrations and movement across three axes. They are smart enough to ignore environmental factors such as wind, rain, snow, nearby traffic and small animals, and still able to detect if there is a real attempt to tamper, climb over or cut through.

Where an intrusion does occur, the nearest detector immediately - within one second - transmits alarm information to a control room indicating the location - within three meters of the preconfigured  zone - thus speeding up security response times.

The system can also be integrated with other perimeter protection products such as cameras or access control systems.

Global enterprise organisations such as Airbus, Total, Eurotunnel and Thales are already using the G-Fence range to protect infrastructure, assets and people. For example G-fence has been installed at one of the UK’s largest water treatment plants, which needed an extra level of security protection, for example, to mitigate against intruders polluting the city’s water supply with a toxic solution. The G-fence was installed along its 200 meter perimeter fence with extra sensors installed on each of the fence’s four swing gates. Another installation at a solar farm helped prevent the theft of expensive solar panels and copper cable, and is more effective than traditional electric fences around the perimeter.

Intrusion detection for any environment

The G-Fence range compliments Heras’ existing  Geoquip High Security PIDS range. Its Cyber Assurance of Physical Security System (CAPSS) approved system - the first and only PIDS end to end solution on the market to have received approval from the Centre for the Protection of National Infrastructure (CPNI) - identifies unauthorised personnel crossing a perimeter and protects the associated IP security system from cyber attack both at the perimeter and at the control equipment within the perimeter.

Physical perimeter security measures are the first line of defence against a malicious attack. Mitigating risk through demarcation and deterrence is important, but for some organisations, also being able to detect intrusion and the location of an attack, can be the difference between a secure site, and one exposed to risk.

Heras believes that, in order to provide the best chance against attack, organisations must take a holistic approach to perimeter security. Its 5D philosophy combines demarcation, deterrence, detection, delay, denying access to unauthorised personnel and controlled access, which together form a reliable layered protection solution to ensure effective and seamless perimeter protection strategies.
