In many cases, electric fencing is your first “active” line of defence against intruders. Electric fencing not only deters would be intruders by making the process of scaling a wall more difficult, it also provides an alarm in the event that the fence is tampered with or shorted out (two wires touch or ground to the earth). Many people also think that “a fence is a fence” (meaning an electric fence), however nothing could be further from the truth. When not correctly installed or wired, an electric fence is as good as useless.
CABLE Logix commonly encounters a number of installation mistakes with existing fences, including: wires starting above the wall line which allows them to be lifted and crept under, poorly manufactured brackets which can easily be bent out of the way, an insufficient number strands in the fence (fences should be a minimum of 8 strands to prevent an average man from stepping over it) and many, many more. Electric fences are also not tested often enough and are generally not connected to the alarm or armed response radio. An electric fence is a key component of perimeter security and must be installed according to best practice to be an effective defence mechanism.
