Fiber-optic perimeter protection

Your fence becomes the sensor.

FIBERMETRICS systems detect mechanical disturbance of an optical fiber: pressure, bending, stretching. They raise the alarm while the intruder is still on the fence, on the wall or on the ground around your building.

How it works

Light in the fiber. An alarm the moment it’s disturbed.

  1. 01

    The analyzer sends light

    The optical fiber runs along the fence, through the ground or the equipment, and returns to the analyzer. The analyzer continuously measures the light that comes back.

  2. 02

    An attempt disturbs the fiber

    Anyone who climbs, cuts, steps or pulls presses or bends the fiber. The returning light changes.

  3. 03

    The panel is notified

    The analyzer evaluates the change and switches the zone output. The alarm panel, siren or floodlight responds.

Why optical fiber

Fewer electronics in the field. Fewer points of failure.

The fiber is passive. It carries no current, needs no power along the perimeter and is unaffected by electromagnetic fields or lightning.

  • Immune to EMI, RFI and lightningIdeal next to substations, power lines, radar and telecoms.
  • Power only at the analyzerNothing to feed along hundreds of metres of fence.
  • Self-calibratingContinuously checks signal quality and warns before a weak signal becomes a problem.
