Comprehensive perimeter protection can only be created by a combination of mechanical and electronic components. Depending on the type of perimeter, this should include exterior protection with fences, crash bollards or other barriers, vehicle sluices with quick folding gates or a barrier gate combination. The experts from French perimeter protection specialist Orep develop integrated solutions together with their clients.

Analysis First
Installing custom-designed systems requires that each project begins with a thorough survey of the proposed deployment site. At the start of every project it is strongly recommended that a team of security experts carefully surveyes and assesses the site. A security risk analysis includes the analysis of current and future security needs and as a reaction the development of appropriate countermeasures to mitigate the risks.
A good partner for perimeter protection offers a wide spectrum of products and services, depending on the individual needs and requirements of a client and is not limited to a certain type of equipment or technology. In the December issue of GIT SECURITY we have provided our readers with an overview about the different technologies that can be used to protect perimeters.

Expertise is Required
Orep has more than 40 years of expertise in the protection of sensitive sites. On the occasion of the French electronuclear program, OREP has developed a system of detector wire netting Peristop. Since that, Orep has specialized in the design, manufacture and installation of intrusion detection systems and the Peristop system is still a key component for their perimeter security installations.

Sensor Net Detection System
Peristop is a 20 cm by 20 cm stainless steel mesh. The mesh is made to be a detector sensor net. All meshes are made with a 3mm stainless steel detection wire and all detection wires are mounted and connected to form a current loop which is an alarm area. The mesh size of the detector is a net vertical resistant barrier which can’t be crossed without deterioration. The mesh sensor Peristop is locked on end braces and posts using profiles and Peristop detection wire.
The system uses detection bent arm systems on the upper part of the fence in order to detect climbing.

The detection bent arms are articulated in both directions, inside and outside. A pressing force increased or trigger an alarm. The Peristop system is managed by an Electronic Control Unit that continuously monitors the status of loops (Monitoring of electrical continuity, impedance, leakage current and short circuits). The breaking of a wire or a grounded causes an alarm.

Intelligent Fence
Part of many Orep solutions is the Perifence+ system, a detector fence that consists of panel with rigid welded mesh. The horizontal tubes are instrumented with sensor cables that detect when there is a cut off. This perimeter detection device is fully integrated in the fence and totally invisible. The detection wire is placed in a way to form a current loop in which, analyzed by an electronic control unit that will constitute an alarm.
