CCTV Surveillance System – Smile you’re on camera!

CCTV Surveillance System – Smile you’re on camera!

We have all seen it and there is no government building, bank or large company (and even small to medium companies and private residences, these days) which do not have it: “This Building is Under CCTV Surveillance”.
CCTV Surveillance has been a part of our lives for more than 30 years (Hollywood has convinced us all big businesses automatically have it) and now it is indeed easily accessible and reasonably affordable for every company and person. However, what is CCTV Surveillance and how does it help secure me and what is mine?

CCTV stands for Closed Circuit Television and consists of the following components:

– Cameras
– Recording device
– Hard drive
– Monitor

With this CCTV Surveillance System, you will be able to view what is happening on your premises and record it for use in any criminal (or disciplinary) procedure. The true value of the CCTV Surveillance System is the deterring factor of it: criminals are uneasy to commit crimes while knowing they are being recorded.

The options for the Customer are staggering – you can receive notifications from the CCTV Surveillance System (i.e. motion sensor, video tampering and loss of power), link your system to an alarm panel, activate features like line-crossing, time schedule, wide-dynamic range, back-light compensation and number plate recognition. At Nelspruit Fencing (Pty) Ltd we can evaluate your premises and needs and recommend the best option for you, also taking into consideration your budget to secure your family, home, employees and business.

Smarter About Security

Smarter About Security

Be Smarter About Security!

In today’s digital age with its technology, it is easy to be smarter about security.  Access control manufacturers are constantly creating smarter systems with easier to use functions, which greatly assist companies of all sizes to effectively control access to their premises.  Furthermore, it allows companies to also secure sensitive areas within their premises, which greatly improves the security of any company whishing to do so.

In this article, we will have a brief overview of the various access control options and later we will write articles about specific smart functions and how it leads to more and better security.

There are mainly 3 ways to control access to your premises, whether it is an office building or a residential complex.

1. Keypad

This is the least expensive of your access control systems and the easiest to use.  It works with a master code which allows the main user to assign codes to staff members and to remove it if the staff member resigns.  The security issue, in this case, is that somebody other than your staff may see what the code is when it is entered which makes the system less secure.  From a cost perspective, the keypad does wear out, which means you will need to replace it at some point.

2. Card Reader

The device itself is not much more expensive than the keypad, however, it involves also procuring the access cards which is then distributed to residents at a residential complex.  The obvious security issue here is in the event somebody’s card is lost/stolen anybody can use the card to gain access at an otherwise secure entrance.  The running cost in this system is the replacement of lost/stolen access cards, not to mention the frustration in constantly replacing cards or providing “loan cards” to staff who forget their cards at home.

3. Biometric Reader

A biometric reader is more expensive than both a keypad and a card reader.  This is because it has no parts to be worn out, which necessitates replacement and as there are no cards to be handed out, has almost no running cost.  It must only be managed from an administration point of view – which is the same for both the keypad and card reader.  Therefore, this system offers the best security when it comes to access control, as people can’t lose their finger and a finger cannot be stolen.

Biometric readers are the current, smart system to use and will become more and more common place.  Additionally, the system comes with software which offers the administrators of it options for fine-tuning and reporting not previously seen.

Nelspruit Fencing (Pty) Ltd installs all these options and will be happy to discuss your exact needs with you.  We will make recommendations based on your requirements as well as your budget.  If you have any queries, please do not hesitate to contact us, for your free quote in Nelspruit, White River, Barberton, Witbank, Lydenburg and Hazyview on 013 742 0004 / /

Safety measures: Electric Fence Certificate of Compliance (COC)

The purpose of the Electrical Machinery Regulations of 2011 (the “Regulations”) is to ensure safety measures are being implemented by the Government.  To achieve that goal, standards and rules are issued to safeguard consumers against using non-quality products and having unqualified installers working on your premises.  These Regulations have been in force since December 2012 and yet it is still a source of much confusion and debate, not only between home owners/tenants, but also between legal experts.


Nelspruit Fencing (Pty) Ltd recommend all electric fence users always err on the side of caution.  In light of the continuing confusion, below we set-out answers to what seems to be main points of concern for users.

1. Do I have to obtain a certificate for my old electric fence?

As a matter of fact, you do not need to obtain a COC if your fence was installed before December 2012.  However, if you are adding or making an alteration to your electric fence, or if you are selling your house, to comply with the set-out safety measures, you will have to provide a COC.  Despite this interpretation of the law, when applying for home owners’ insurance, it is prudent to confirm with your insurance company that your fence was installed before December 2012 and you do not have a COC for it.

Moreover, if your home is part of a sectional title which has an electric fence, the body corporate must have a COC and a copy of it will be sufficient to add to your transfer documents.

2. What happens if I do not obtain a certificate for my fence?

In the first place, if your fence was installed after December 2012 and you do not have a COC, anybody suffering damages or physical injury (even if it was a criminal illegally trying to gain access to your property) may have a legal claim against you for such damages or injuries suffered.

Additionally, the regulations confirm that if an electric fence is installed without the issuing of a COC, it will be in breach of the aspired safety measures and therefore the owner/lessor shall be guilty of an offense and liable upon conviction to a fine or to imprisonment for a maximum of 12 months.  Moreover, in case of a continuous offense, the user/lessor may be liable for an additional fine of R200 or additional imprisonment of one day for each day on which the offense continues.  However, the maximum period of such additional imprisonment may not exceed 90 days.

On our website we have a section dealing with the COC (, however, we will be running a series of articles regarding the Electric Fence COC, to help consumers and to explain various aspects of the requirements.  Please let us know if there is any specific question you would like us to address, either by commenting below or emailing us at  For information re the services we offer, please visit us at

“Know Your Products”: Security Electric Fences – 5 or 6 lines?

You, as consumer, are faced with so many options of electric fencing products, we at Nelspruit Fencing (Pty) Ltd decided to launch a series of articles called “Know Your Products”.

This is the first “Know Your Products” article and is written to explain to consumers why you should never have a 5-line electric fence.  The first bit of information to take note of is that one of the most common ways an alarm on a security electric fence is triggered, is when the earth and live wires touch.

Below we made a drawing showing the electric current on a 5-line fence.  You will note the top 2 and the bottom 2 lines are live wires and only the 3rd wire is an earth wire.  This means that only if the 2nd or 4th line connects with the 3rd line, an alarm will be triggered.  This is impractical as an intruder will not try to climb through the middle of your security electric fence, but under or over it.


Below we made a drawing showing the electric current on a 6-line fence.  You will note that if the top or bottom 2 lines touch each other (which is where an intruder is most likely to try and enter) the live and earth wires connects and an alarm is triggered.  In addition to the top and bottom 2 lines, if the 2nd and 3rd or 4th and 5th lines connect it will also trigger the alarm.

Do not let anybody try and convince you a 5-line fence is sufficient as a Security Electric Fence, just to save costs.  Above we have demonstrated why it is most definitely not the case.

We are happy to discuss any further topics – please let us know if you have any questions about this article or any other topic related to security solutions, either by commenting below or emailing us at  For information re the services we offer, please visit us at

Cut Wire and Earth Short test: how to check if your Electric Fence Security System is working properly

Testing your electric fence security system.

How do you know if your electric fence security system is working properly?  Those of you who are not installers by profession, may not know that to trigger an alarm the electrical current in your fence has to be broken.  This can happen in many ways, the 2 most common ways which will indicate an intruder is a cut wire or if the Live and Earth wires touch each other as someone tries to climb over your fence.

The ‘Cut Wire and Earth Short Test’.

Apart from merely trusting the installer doing work at your premises or studying up on electric fence security systems yourself to ensure you understand how it works, there is one easy way to check:  the Cut Wire and Earth Short Tests.  To ensure you have a proper electric fence security system, it is imperative that both these tests are done.

Installers should show you the alarm system works.

Upon completion of your electric fence security system, your installer must show you that if a wire is cut the alarm is triggered.  This can be achieved by removing a bridge or by cutting a wire and repairing it (Cut Wire Test).  In addition, the installer also must make a short between the Earth and Live wires by putting some object in connection with both (i.e. a screw driver).  This simulates somebody pressing the wires together as if they were trying to climb over the fence.  Once the short between the Earth and Live wires are made the alarm must be triggered (Earth Short Test).


Ensuring effective and relaible security services.

Nelspruit Fencing (Pty) Ltd will always ensure our customers have been shown that their electric fence alarm system works, by performing these tests and always ensures any questions the customers have is properly answered so that our customers understand all they need to know about their electric fence.

This is one of the tips to be sure you receive quality service.  We are happy to discuss any further topics – please let us know if you have any questions about this article or any other topic related to security solutions, either by commenting below or emailing us at  For information re the services we offer, please visit us at

Electric fence alarm system with pin-point ability

Electric fence alarm system installations have become common fixtures in South Africa. When an alarm is triggered on an electric fence alarm system the owner of the fence is alerted to an intruder and can take the necessary steps to protect himself, his family and his property.

But what if you are in the middle of a farm with an electric fence spanning more than 10 kilometres? How do you know where the breach has occurred? With the continuing improvement of fence and security technology the answer is quite simple.

JVA ZM20 - electric fence alarm system

JVA ZM20 – electric fence alarm system

By combining JVA’s ZM20 with a GSM Module, Nelspruit Fencing will split up your kilometres long fence into sectors and if an alarm is triggered in one of these sectors you will receive a text message (or email or Facebook notification, whichever you prefer) which will notify you of the sector in which an alarm is triggered.  This means you will be able to immediately direct your attention to the correct area, instead of traversing your entire fence before reaching the cause of the trigger.

In addition to directing you to the correct sector which is triggering an alarm, the ZM20 and GSM Module will also keep a careful log of any time when your energizer has been switched off and by assigning different codes to the different users, you will be able to see which user has switched off your energizer.


Clearly the electric fence alarm system will serve our farmers in and around Nelspruit (and anywhere else in Mpumalanga) well.  You will no longer waste precious time looking for the criminals on your farm to find out where in your crop they are stealing from, you will be able to zone in on them immediately.
