Flexible fences, like chain link fences, can be easily and effectively protected by attaching a plastic fiber cable LiteWIRE to it and connecting the cable to an analyser, LiteFENCE. This analyser sends and receives an encrypted optical signal, which cannot be tapped or replicated, and continually checks for variations generated by stresses on the plastic fiber. When the signal received by LiteFENCE has variations or interruptions, the analyser generates an alarm. LiteFENCE is not sensitive to vibrations on the plastic fiber, which eliminates false alarms caused by vibrations (e.g. weather conditions, vehicles passing by…)
All the area inside and outside the fence remains fully available and walkable: people and vehicles can move near the fence also when the perimeter protection system is active. Anti-intrusion detection can be kept active also H24.
