Electric Fencing

Highly effective electric perimeter fencing makes it possible to detect and keep intruders from entering your premises.

  • On 24 Hours a Day
  • Detecting Intruders
  • Deterring Intruders

Residential: minimum of 8-strands;

Basic`s that makes electric fencing effective

  • Bent Outwards

  • Antilift Brackets

  • Well Tentioned Wires

Commercial or Complexes: minimum of 12-strands.

Electric fencing is highly effective in both detecting an intruder and deterring him from entering your premises. The quality of your installation is directly related to the effectiveness of your fence. Wherever possible Electric fences should be wired in series with alternating live and neutral strands with gaps of no more that 100mm, the final height of your fence should exceed “crouch height” to prevent stepping over.

Full Free Standing Electric fencing starting at 20-strands and 2 meters high but recommended to be 2.4 meters high with 24-strands. Once you have installed your Electric fence the greatest risk of a perimeter breach even though this chance is very small is the possibility of a person digging under your full fence or smashing through your pre-cast wall. The risk needs to be assessed and the following can be done to reduce or eliminate this possibility. The bottom strand should always be live!


  • To lay a full concrete foundation below the fence (300mm x 300mm wide and deep).

  • To install anti-lift hooks (figure of 8) – this will ensure that entry can only be gained by digging a full hole not just lifting the bottom strands. Attached to the wall or knocked into the ground.

  • Floating Anti-lift Rings – Have also become very popular due to break-ins where wires have been separated. At least 4 Anti-lift Rings between brackets on full freestanding fences. At least 2 Anti-lift Rings between brackets on wall top fencing. All to be used in conjunction with the figure of 8 Anti-lift Rings.

  • A live anti-dig (offset bracket) strand +/- 50mm off the ground and +/- 200mm in front of your freestanding fence.

  • Pre-cast walls should have 24-strand Piggy Back Fencing from the top to bottom wherever there is open land, veld, Golf Courses or a river behind as this has proven to be the most likely form of entry if only Wall Top Electric Fencing is installed

  • Support posts should be 3 meters apart


It is important to install the correct sized energizer for your type of fence as too small or too large an energizer will only create false alarms. All energizers produce between 8000 and 10 000 volts at a low frequency of 1 pulse per second and at low amperage. The power/energy of the energizer is determined by its joules starting with 3.5 joules for short fences and going up to 8 joules for long full fences.


This is the joule energy on the fence and in order for the unit to be legal, must comply with the Government Gazette regulations, it is however possible to store greater joules in the capacitor. The alarm monitor is the most important factor on your fence and must be kept in good condition and tested regularly. Single zone, dual zone and 20 zone energizers are available to determine where the breach has occurred on your fence. All our energizers comply with government regulations.

Various Accessories are available:

  • Red Flashing Light – To warn you of an activation while you were out

  • Remote/Hardwire armed Response Linkup – To link to your Armed Response company

  • Gate Magnets – To monitor forced entry on the perimeter

  • Lightning Protection

  • Series Gate Contactors – To ensure wires on sliding gates give an alarm when cut

  • Remote On/Off Ability – Control via remotes

CCTV Camera's

Specialists in the installation of CCTV as this industry has grown and changed tremendously in the past few years.

A wide range of product is available from the simple single camera and gate monitor to the multi camera digital computer system.


Are available with various size lenses to ensure that you are able to see the picture you require whether that be focused close up or a wide angle picture to see motion in the vicinity.
Colour cameras require a lot more light to give a good picture so generally external cameras in residential installations are often infrared. Monitors can be linked to view your camera from 4 inch up to 52-inch monitors also available in high quality colour LED. With the use of a Converter, the signal from your camera or multi-switcher can be placed directly onto your television network.

Day Night Cameras – Infrared

Colour by day, Black & White by night, even when in pitch black conditions. This is achieved by fitting infrared LED lights to all these cameras. Night vision ranges are variable:

• 10 Meters
• 25 Meters
• 40 Meters
• 60 Meters
• 100 Meters


Cameras can be switched from picture within picture screens to timed switches dealing with 2 cameras up to 32 or quads can be used to view all your cameras at once.


Can be achieved with a conventional recorder or a 24 hour time lapse recorder. The use of a Multiplexer ensures the recording of multiple cameras and their playback.

DVR = Technology is the answer!

Analitical software can now track people moving and create alarms

The digital computer has revolutionized the CCTV market making it possible to record directly on Hard drives with time and date stamped and easy searching for recorded events. Pictures are only recorded when motion is detected thus saving time and space. Alarms can also be created when motion is detected. Available for 4 to 32 cameras – this computer based system must have a stand-alone computer dedicated to its operation (Embedded DVR). Fixed monitors can be connected prior to being recorded to ensure real time smooth pictures for Control Rooms.
Full switcher and quad capabilities are standard.

Real Time digital video recorders are available. 

Recording up to 400 frames per second, divided by the 16 cameras as per system. Large hard disk drives are required to store this video footage. For this reason units that record at 100 and 200 frames per second are more popular.

The Digital Video Recorder is able to be remotely accessed from anywhere in the world via a modem & telephone line. The pictures are also able to be played onto your LAN (Local Area Network), giving selected and trusted staff members the ability to monitor vital areas of your business.

Embedded stand alone DVR’s are by far the most reliable recording platforms and are highly cost effective.
