FENCE INTRUSION DETECTION SYSTEMS

movement to people and animals, while protecon remains h24 acve. This is an important advantage on other tradional soluons both in industrial and residenal areas, where people can pass by the fence and vehicles can be parked very close to it without triggering any alarms. Besides, the plasc fiber woven through the fence is safe, because only light is transmied, not electricity, so it doesn't aract ground loops or electromagnec interferences.

There is a well-established, reliable technology for perimeter intrusion protecon on flexible fences which enables the owner to react promptly, because the system detects real intrusion aempts before the intruder has got inside the property. The system LiteFENCE, which is 100% made in Italy by Naria Security, has proven extremely effecve over the years, as well as easy to install in every environment. The same technology can be also applied to barbed wire or metal rope running on top of perimeter walls.

The LiteFENCE system combines an analysing board (LiteFENCE) with a performing, sunlight resistant plasc opcal fiber (LiteWIRE) and specific tensioning bolts. LiteFENCE reveals the intrusion aempts which result in a flexion of the fence: climb over and li of the fence, as well as aempts to create a breach. The analysing board communicates to any alarm panel via a normally closed relay. Aer an alarm, if the fiber has remained intact, the system resets automacally, and goes on working regularly This intrusion detecon system can easily suit sloping grounds and perimeters of irregular shape because the system runs along the fence and becomes one with it. The plasc fiber cable is “woven” along the mesh in two or more passages and is connected to the analysing board LiteFENCE: this board detects when the fiber is flexed or interrupted, because the intensity of the light signal transmied in the fiber changes. Vibraons do not flex the fiber and do not result in changes in signal intensity, so the whole system is insensive to vibraons: for this reason, it is parcularly robust to false alarms. Unlike other technologies on the market, LiteFENCE is effecve in any weather condions (rain, snow, wind, fog…) as well as in presence of small animals or birds.

As the an-intrusion system and the fence are intertwined, the nearby area remains free and available: this guarantees freedom of www.nariasecurity.it

The analysing board is incredibly user friendly: it has a built-in power meter, which help the installer monitor if the plasc fiber is being placed correctly or idenfy any problems. Once the fiber has been installed and the sensivity level set, no further calibraon is needed. Temperature and humidity slow changes are compensated automacally by the board. Vegetaon growing slowly on the fence does not interfere with the system either, so there is no need of regular or constant maintenance Of course, it is good pracce to trim vegetaon when it becomes heavy and interferes with the flexion of the fence. Unlike tradional glass fiber, plasc fiber is very easy to handle, terminate and repair for everyone, because no skills or expensive tools are required. Pung a connector on the cable only requires a few seconds, and the reparaon of a plasc fiber cable can be carried out quickly and inexpensively by any installer everywhere.

Security soluons over plasc opcal fiber have been on the market for more than ten years and have proven very effecve and easy to manage. This perimeter intrusion detecon system is as reliable as all the other security soluons developed by Naria Security, which engineers and manufactures also an-the systems for copper wires, photovoltaic panels, farm and industrial equipment and machines.
