Electric Fencing

Electric fencing is one of the most cost effective, electronic perimeter breach deterrent & detection systems available.

How does an electric fence work?

  • The system works by sending a high-voltage electrical pulse around a multi-wire perimeter fence, the potential involved may be on the order of 2,500 to 12,000 volts, the current is limited to a safe level and the actual pulse lasts only milliseconds.

  • The source of the high-voltage electrical pulse is an electric fence "energiser"

  • When an individual trying to breach the fence, comes into contact with the fence by climbing over/under, the "Live" fence will become part of an electrical circuit between the output terminals of an energiser, a high voltage pulse will flow through the body of the individual to the closest earth, leaving the perpetrator temporarily incapacitated.

  • The strength of the shock depends upon the power available from the energiser, and the total resistance of the circuit.

  • Electric Fencing not only offers effective protection but also a psychological deterrent, if the fence wires are deflected by vertical movement, contacting strands either side or cutting the strands, the system will cause a short circuit on the fence line, and trigger the alarm, giving an audible and visual indication of a fence breach.

  • The fence controller is a monitored alarm system; the fences can be zoned for easier detection of breaching.

  • False alarms are virtually non-existent, as the fence will only go into alarm when a concerted effort is made to break the perimeter security.

  • Our existing clients have reported the system as paying for itself within twelve months of installation.

  • To date this system has proven to be a very reliable and highly effective security system. In sites previously subjected to a number of attacks the system has eliminated all losses and in some cases removed the need for a resident security guard.

  • The system is capable of protecting and controlling anywhere from one to 100+ zones each of 50-150 meters in distance. This provides a very flexible solution for most requirements.

The advantages of an electric fence:

  • Easy installation on existing wall or fence, or as a stand-alone perimeter fence.

  • Provides a physical barrier that delays the intrusion time.

  • Provides an electric high voltage shock to intruders.

  • Acts as a psychological barrier to deter intrusion attempts.

  • Provides a higher level of detection capability to detect an intrusion attempt and set off the alarm, which can then be transmitted to the security personnel or company monitoring the site.

  • Low maintenance costs.

  • Easy of operation.

  • Animals that receive an electric shock and are deterred without activating the alarm. Animals learn very quickly not to come into contact with the fence

  • Accidental human contact with the fence will provide an electric shock that will alert a person not to tamper or come in contact with the fence.

  • The electric wires also serve as a perimeter fence, alleviating the need to erect additional, fencing.

  • Reduced cost of security personnel.

The function of an electric fence is:

  • To keep intruders outside

  • To secure the residents inside the perimeter.

  • The structure must be stable and high enough.

  • The voltage must be as high as possible within legal requirements.

  • The siren that is part of the energizer must go off if tampered with the fence.

  • The alarm can be linked to armed response for extra security.

The necessity of electric fences and electronic fencing in South Africa

  • A perimeter protection at government properties.

  • Securing complexes and estates.

  • Around private dwellings in towns or cities

  • To protect factories.

  • For game farms.

  • To secure the farmhouse and buildings on farms and small holdings.

Electric fences at estates, complexes and large corporate parks. Secure All Security provides the following;

  • One energizer per zone. ( When a fault occurs the whole fence is not out of order.)

  • All wires to be energized.

  • Each energizer can be separately switched on or off.

  • Alarm received in guard room for every energizer  ( zone)

  • Control of guards - they are forced to visit the problem zone.

  • Energizers can be repaired on site, no unnecessary waiting periods.

  • Energizers can be linked cameras and access control to form an integrated system.
