What are the benefits of our security installation services?

An electric fence is an excellent deterrent to intruders and keeps criminals from gaining easy access to the premises. A simple palisade fencing or razor wire will not provide an alarm notification should the fence be tampered with.

The electric fence acts as a physical barrier, a psychological barrier and an early warning system. Therefore it causes a delay when entering the premises as well as when wanting to exit.

The electric fence can stay on for 24 hours at a time, whereas a normal alarm or perimeter beams are generally switched off when there are visitors.

You have peace of mind knowing that your family is safe when you are away from home, and provide you with a back-up plan for when you are at home. It is always good to know that someone else is on the way when you are faced with intruders in the middle of the night.

Frequently Asked Electric Fencing Questions

  • Q.How safe is electrified fencing with children?

    A.There are certain restrictions set out by SAEFIA (South African Electrified Fencing Installers Association). The energizer that is installed will need to conform to these restrictions. With this electric fencing is 100% safe, and is used for game farms, agriculture, livestock to residential property and businesses

  • Q.Is this system safe, and can the fence kill my cat?

    A.No, animals, especially cats sense the magnetic field of the energizer pulls. In other words the fence gives off negative irons into the air which the animals can pick up through smell. Therefore they tend to stay away from the fence.

  • Q.How many volts are there on the fence?

    A.It depends on the type of energizer. This can range from between 4000 volts up to 10,000 volts for residential fencing.

  • Q.How much more will my electricity bill be when I install an electric fence?

    A.The energizers don’t draw much power. There you should not pay more than R100 extra per month

  • Q.Where does electric fencing originate from?

    A.Electric fencing originated from the agricultural field to protect stock and the control of grazing. Over the years this technology has developed to such an extent that there are now various levels of sophistication depending on specific requirements.

  • Q.How does shrubbery and grass affect the electric fence?

    A.All shrubbery contains moisture which forms a conductor down to the ground. The more growth touching the fence, the less effective the electric fence becomes.

  • Q.Does electrified fencing work?

    A.Yes, you need to plan your electric fencing around your particular needs. As we know for every action there has to be a re-action. The electric fence works when it has been configured correctly and you get a notification. Then you can respond accordingly.

  • Q.What happens when a blanket is thrown over the fence?

    A.Again, if your fence is configured correctly it should give an alarm output from the control panel that excess weight on the fence, or parting of the conductors has taken place.

How does Electric Fencing work?

Electric fencing was originally developed to confine animals to a certain area. Due to a serious security demand, this technology was improved and a very effective barrier system for unwanted intruders was developed.

The actual system sends a high-voltage electrical pulse around a multi-wire perimeter fence. The source of this is called an energizer.

One terminal is connected to the live wire circuit and the other to the earth wire circuit, which is also connected to a metal rod planted into the ground.

The energizer works on a send and return basis, whatever voltage it sends out, it must receive back.

There are 2 x alarm conditions on a fence. A short circuit- when a ground wire and live wire is touching. An open circuit- when a wire is cut.

The potential of the pulse may vary between 2,500 and 12,000 volts, depending on the equipment that is used.  The electrical current is set at a safe level so the pulse lasts only for a few milliseconds at a time, making sure that the end result is non-lethal.

What happens when the intruder tries to breach the electric perimeter fence? He becomes part of an electrical circuit and as the high voltage current travels through his body, he will be shocked and temporarily incapacitated.

Monitoring can happen in a number of different ways:

  • Wires are redirected by vertical movement, or
  • There is a contact between the live and earth circuits, or
  • The wires have been cut

The system will cause a short circuit on the fence and the alarm will be triggered. This will give a noticeable and visual indication of a breach.

Often perimeter fences that run a few kilometres long can be zoned to detect where the breach took place. This is very effective as the guards can get to the entry point quickly.

This technology has become so advanced that you can monitor and keep an eye on your system from anywhere in the world. You will be able to arm and disarm your system, be notified of any alarm activation, be notified of power failures, and any other features…

It is recommended that you connect your electric fence alarm to a security company for extra protection and monitoring.
