VCS-600 Fence Vibration Detection System

A new-generation fence-following detection system for cutting, climbing and lifting attempts — stable detection even with multiple simultaneous intruders and heavy environmental noise.

CE — EMC Directive 2014/30/EU FCC Part 15B Verified PD ≥ 95% / Confidence ≥ 95%

How It Works

A sensing cable is tied along the fence fabric. The VCS-600 processor monitors microscopic bending of the cable at high sampling speed, capturing the characteristic signature of cut, climb and lift attempts anywhere along up to 600 m of fence.

Unlike single-zone sensors that aggregate everything across a run, VCS-600 divides the perimeter into independent software-defined segments and analyses each on its own signal signature — maximizing probability of detection while suppressing false alarms from wind and rain distributed elsewhere on the line. Sensitivity, filters and vibration-count parameters are tunable per segment in software.

Power and data travel through the sensing cable itself, minimizing site infrastructure. Redundant communication keeps the perimeter protected even if the cable is cut. Adaptive environmental processing, per-segment zoning and software-programmable relays make it integrate cleanly with any alarm management platform.
