It’s Time To Upgrade Your Existing Electric Fence Hardware
Crime does not sleep. It also does not respect private property. We can however take steps to either make it more difficult or to discourage such invasions of property in the first place. There are many ways in which this can be done, but a common (and cost effective) method in South Africa is the use of an electric security fence. It adds an additional layer of security to your property, keeping unwanted guests out and helping you feel safer. This article will examine the use of this kind of hardware technology in protecting your property.
Adding another layer of security
The electric fence is a simple, yet effective, piece of hardware that can enhance the physical security of most properties. In most cases, only a single barrier, like a brick wall, stands between the outside world and your property, making entry relatively easy. With an electric security fence and the right kind of hardware installed, this barrier effectiveness can be improved. Electrified fences are thus a great cost-effective solution for people who want to protect their property.
Like any barrier, electrified fencing works as a deterrent by discouraging people (and animals) from attempting to cross it or to break through, and thus serves as both a physical and a psychological barrier. It is a physical barrier in that it creates an obstacle with direct physical feedback (a non-lethal electric shock) and it serves as a psychological barrier in the sense that people and animals associate it with danger and thus become discouraged to attempt to circumvent it.
Get Your Electric Fence Hardware From Nemtek
Criminals find new ways to bypass electric fence hardware all the time, but we are also constantly learning how to counter the techniques they use. These techniques can range from basic mechanical adjustments like ensuring the wiring has enough tension and the energisers are functioning appropriately, to more advanced changes like adding our Dual Action Tension Sensors (DATS) to a new or existing fence. These sensors can be retrofitted onto most electric security fences to prevent intruders from pushing down on your fence or attempting to separate the wires. Nemtek can advise you on any adjustments that need to be made, so give us a call.

Everything you need to know about Energizers for Electric Fences
What is an energizer and how does it work?
An energizer for an electric fence (security or animal management) is used to convert battery or mains power into electrical current pulses which are sent down the fence. The energizer sends out pulses instead of a continuous current to eliminate the risk of dangerous shocks that could be received and allows the animal or person to step away/let go of the electric fence. Nemtek security energizers have the functionality to monitor the fence wires and can alert you, in the form of an alarm, if anything changes in the condition of the electric fence.
The fence circuit remains closed and the pulses flow through the fence until one of two events happen: there is an open circuit or a short circuit. An open circuit happens when a live wire is cut and the current is disrupted which sends the energizer into alarm. A short circuit can occur when either a person or animal touches a live wire and completes the circuit by the current flowing through them into the ground and earth spike, or when an earth and live wire touch when someone is trying to climb over the fence. This will also send the energizer into alarm. Without an energizer, an electric fence is just a couple of wires or a passive barrier.
Things to consider when selecting an energizer:
- Which industry are you addressing?
This will determine what type of energizer you will use. For example, a residential fence may require one zone of 150m whereas a high-security fence may require multiple smaller zones for patrolling.
- How many zones do you require?
This depends on the length of the fence and the zone lengths required.
- How the information is displayed.
- On the energizer LED
- On the energizer LCD
- On a keypad
- On a touchpad display, generally used with multi-zone systems
- On a PC in a control room, large systems
- Joule rating of the energizer
The higher the joule rating, the higher the energy that an energizer can deliver into a load.
The Nemtek difference 
Nemtek designs, manufactures and distributes a complete range of innovative and intelligent electronic perimeter control systems that are easy to install and use. We supply both the security and animal management industries with high-quality products, which have been thoroughly tested in a competitive market. We are so confident in our range that they come with a two-year warranty.
Using the Adaptive Power Technology (APT) pioneered by Nemtek, our energizers are capable of detecting how much power a fence can accept and handle before it starts to arc and waste energy. This maximises the power on the fence and minimises false alarms.
We specialise in the research, development and manufacture of electric fence energizers and related products. This includes medium- to high-powered units. Full SABS and IEC reports are available on request.
