Fence Sensors Frequently Asked Questions

What Are Fence Sensors?

Fence sensors compared to other technologies are sensors mounted directly on the fence to detect intruders attempting to cross at the fence line. The purpose of the fence sensor is to detect them on the way in and provide early warning. The fence sensor comes in many shapes and forms: Cable either from copper or fiber optic, accelerometer-based mounted on a non-sensitive cable and others. Most fence systems work with various types of fence types, including chain-link, welded mesh, concertina coil, bard wires, anti-crash barriers and palisade.

Why Choosing Fence Sensors Over Other Technologies?

When looking to effectively monitor a fenced perimeter no other technology can provide effective 100% detection with no gaps. The sensor cable covers the whole perimeter at any angle and no matter how many turns or changes of elevation. Another advantage of the sensor cable is a single point of power and communication vs IR Beam sensors which need multiple.

How Do Fence Sensors Work?

The sensor cable is designed to pick up vibrations of the fence it's mounted on. The algorithm of detection is designed to detect only sharp frequency vibrations associated with intrusion attempts while filtering the low frequency vibrations from the weather are ignored resulting in discrimination between real intrusions attempts and environmental noise.

Why is the IRONCLAD is an Armored Fence Sensor?

The IRONCLAD comes with an integral armored layer made out of stainless steel, compared to other ``armored`` sensor cables this layer is an integral part of the sensor and cannot be separated. The additional cable protection allows installation on razor wires and concertina wire.

What are DAS Fiber Optic Fence Sensor Cables?

A DAS sensor is an advanced variant of an Optical Time Domain Reflectometer (OTDR) that monitors the coherent Rayleigh backscatter noise signature in a fiber optic cable as pulsed light is sent into the fiber. The coherent Rayleigh noise generates a fine structure in the backscatter signature of the fiber cable. The DAS focuses on the Raleigh component to increase its prominence in the backscatter trace. Very small physical (acoustic or vibration) disturbances events at a point in the fiber can make detectable changes in the interferometric signal.
