Many South Africans install electric fences as part of their security measures at home. Often a house alarm or high fences are not enough and burglars still manage to enter their properties. People who life in high-risk areas make use of all the available systems to protect themselves, their families, and their valuables. The first line of defence is to prevent intruders from entering your premises and if they still do, you want to be forewarned which is exactly what will happen when the alarm is triggered. Do not switch the alarm off when it triggers continuously, criminals often use this method to irritate house owners.
A great number of farmers make use of the services of electric fence installers; they fence the entire farm or the homestead in the fight against thieves and murderers. Stock theft is a reality of the day and the fences are installed in an effort to minimize losses. Many industrial sites install electric fences on top of their perimeter walls to prevent unwanted entrance to their premises and to protect their valuable stock.   
An electric fence is only a deterrent if it works therefore it is essential to check the fence regularly. Walk or drive along the fence and remove all vegetation. Cut back trees and shrubs. Test the fence by making use of a wire attached to a wooden pole, by creating your own short you will find weaknesses in the fence.
Electric fence installers should have a proven record of accomplishment. Ask your friends and family which companies they are using and whether they are satisfied with the service the company provides. A neighbouring farm or household who uses electric fencing will also be able to give advice on which company to use. Do an internet search and look up the companies who advertise their services on the web. Many installers are members of the South African Electric Fence Installers Association (SAEFIA) and as such, they subscribe to the rules and standards as set out by the association.
