Alarm on perimeter fences

A property can be protected from intrusion attempts by securing its fence with a suitable perimeter intrusion detection system. This allows to detect intrusion attempts when the intruder is still outside the property, so the reaction time to cope with the intrusion is longer.
During an intrusion attempt, oscillations, vibrations or flections are created on the fence, depending on the type of fence itself: for this reason, there are different ways to secure it. Naria Security’s protection systems detect, sort and transmit these mechanical stresses to LiteFENCE analysers through a plastic fiber cable LiteWIRE: the analysers transmit and receive an encrypted signal, which cannot be tapped or replicated, and analyse it, generating an alarm in case of variations. LiteFENCE analyser is compatible with any (existing) alarm panel via a dry contact relay.

NO FALSE ALARMS: one of the main critical aspect of perimeter protection are false alarms. A fence is on the boundary of a property, often in areas which are little visible and little maintained, as well as surrounded by vegetation and completely exposed the weather. In addition to it, different types of fences (or even the same type of fence installed in different ways) may react in different ways to the same mechanical stress. Naria Security’s systems are auto-calibrating and designed to filter all these interferences both mechanically and electronically, proving to be very robust to false alarms.
