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.
