Electric Fencing

Stemar Security Systems’ journey began in 1989 as electric fence installers which was the core of our business for several years. We soon became the recommended and official contractors to most of the major armed response companies in Johannesburg at the time and have thousands of electric fence installations under our belt. 

Electric fencing is considered as the first line of defence in a typical security setup. It creates a physical barrier that delivers a 10,000-volt shock when touched as well as a perimeter alarm system. The electric fence registers an alarm by monitoring the return voltage to the energiser. Should the fence voltage drop below a pre-set value, e.g. 3000v either from the wires being cut or blankets / object thrown over the fence, the energiser will trigger an alarm.

Electric fencing must be installed in accordance with legislation set out in the regulations of the Occupational health and Safety Act required by the South African National Standards (SANS 10222-3:2012).

As per legislation passed in 2012, properties can no longer be sold without an EFCC (Electric Fence Compliance Certificate) which can only be done by registered and certified individuals.

We specialise in three types of electric fencing:

Wall Top Electric Fencing:

Wall top fencing secures the area above boundary walls and gates preventing intruders from simply hopping over. The most commonly installed wall top fence consists of 8 strands of wire which provides a barrier of 900mm in height. Fence poles must not be spaced more than 3m apart and additional poles should be installed to reduce gaps created by wall steps.

Piggy back electric fencing is usually a multi-strand fence installed from ground level up which and attached to an existing structure such as a precast wall, mesh or steel palisade fence

Piggy Back Electric Fencing:

Free standing electric fencing is a multi-strand fence using its own poles for support. The fences vary in height with the average being between 1.8m (18 strands) to 2.4m (24 strands)

Is Electric Fencing a good deterrent?

Electric fencing can be a highly effective deterrent against potential intruders and unauthorised access. It works by delivering a non-lethal but powerful electric shock to anyone attempting to climb, cut or breach the fence. The shock is enough to create a strong psychological and physical deterrent dissuading trespassers from attempting to breach the perimeter.

Here are some reasons why electric fencing can be a great deterrent:

  1. Psychological impact: The presence of electric fencing alone can deter intruders. They recognise the risks associated with attempting to breach it and may choose to avoid the property altogether.
  2. Physical barrier: Electric fencing provides an additional physical barrier beyond traditional fences making it more difficult for intruders to gain unauthorised access.
  3. Alarm system and integration: Electric fence energizers include alarm outputs for sirens and strobe lights to create an audible alarm and visual display when breached. Energizers can also be integrated with alarm systems alerting armed response companies, security personnel or residents when the fence is tampered with or breached.
  4. Cost-effective: Compared to some other security measures, electric fencing can be a cost-effective solution for securing large areas or perimeter boundaries.

While electric fencing can be an effective deterrent, it is important to note that no security measure is foolproof. Combining electric fencing with other security systems such as CCTV cameras, outdoor alarm beams, access control and manned security personnel can provide a more comprehensive and robust security solution. The effectiveness of electric fencing also depends on proper installation, maintenance and adherence to local regulations and safety standards.

Electric Fence Legislation

The effectiveness of electric fencing relies heavily on correct installation and proper configuration. Unfortunately, the growing number of poorly installed and misconfigured electric fences has posed significant security risks to individuals and their property.

To address this concern and ensure the safe and efficient implementation of electric fences, legislation was introduced in 2012 to regulate electric fence installations. This legislation aims to set specific standards and guidelines for the installation and operation of electric fencing systems, ensuring they meet safety requirements and adhere to industry best practices.

By enforcing electric fence legislation, authorities can mitigate potential hazards, reduce the likelihood of accidents or malfunctions, and hold responsible parties accountable for any negligence or non-compliance. Consequently, it promotes a higher standard of security and safety for the public, property owners, and the security industry as a whole.

To access the specific regulations and guidelines governing electric fence installations, individuals should refer to the legislation in place in their respective regions or consult relevant authorities responsible for overseeing security standards and practices. Complying with these regulations is crucial in maximising the effectiveness of electric fencing while minimizing risks to people and their possessions.
