The impact of COVID-19 and the methods to fight it has impacted all our lives.  With many companies now back at work, the sanitation of communal office equipment has an even higher priority.  Nelspruit Fencing can provide “touch free” access control for your staff, so that access control in your office will not lead to any COVID-19 worries. 

For entrance into your office we will install a biometric reader, which works with access card or tokens as well.  Each staff member will be assigned a card or tag, so that you will also be able to obtain logs of when your staff enters the office. 

We usually recommend access control at companies to be run with fingerprint access, as it is more secure, but in the fight against COVID-19, it seems safer to rather request staff to carefully look after their access cards so that you can ensure there is no cross-contamination on your access control reader.  Furthermore, the reader we will install will be compatible with both fingerprints and access card or tags, so the option will be there to, at a later stage, programme your staff’s fingerprints on the access control reader. 

For staff (or anybody else) to leave your office, we will install a “No touch” exit button.  The clue is in the name:  You simply hold your hand in front of the exit button and the door will open.  Zero chance of cross-contamination, regardless of how many staff or visitors you have at your office. 

Nelspruit Fencing has all the necessary qualifications and expertise to assess your office or complex and make the necessary recommendations in line with your requirements, needs and requests.  Contact us from Nelspruit, White River, Barberton, Lydenburg or Hazyview for your free, no-obligation quote on +27 74 104 6028 /, or visit our website at

Common Electric Fence Mistakes

Common Electric Fence Mistakes

While doing repairs and generally driving around the Lowveld we have noted a few common mistakes made when electric fences are installed.  These electric fence mistakes are made by installers who are not properly trained, and which mistakes will impact negatively on your electric fence’s performance.  Finally, it is also these common electric fence mistakes which make people believe that electric fences do not work.  (Have a look at our “Do electric fences work?”  Articles,,


Here are the most common electric fence mistakes.

The bridges are built wrong, so that your electric fence is not really in series or parallel.

This is a bit of a technical issue, which we’ll be happy to explain to you on site, but basically it means instead of having a proper security fence or a proper gaming fence, you have neither. 

HT cables are installed in polyethlene pipes (poly pipes) instead of proper PVC conduit and pipes are not sealed.

These poly pipes are soft and flexible and do not provide proper protection for your HT Cable when you bury it.  The HT Cable is the cable which connects your energizer to your electric fence and as such must be properly protected.  Additionally, if the pipes protecting the HT cable are not sealed, when it rains water will accumulate in your pipes and this will cause your 8,000 volts cable to be submerged in water. Obviously, this is a terrible idea.    

There are not enough earth spikes for the length of the fence.

If you do not have enough earth spikes for your fence, your fence will not be properly earthed.  The electric shock of a fence which is not properly earthed will not be as painful as the shock from a properly earthed electric fence and therefore your deterrent of an electric fence is severely minimised.  There are several other technical issues, which again, we’ll be happy to share and explain on site, (i.e. induction, capacitance, etc.)

There are no lightning diverters.

This is a COC requirement and as it is not an expensive part of the fence, we always install it to try and minimise the risk to your energizer.  Your energizer is the most expensive equipment of your electric fence, so it is well worth doing what you can to try and protect it. 

In order to obtain a COC many fences (especially free-standing fences) require a barrier fence.

This is a source of great contention between installers, complexes/estates and the Electric Fence Regulators and needs an article on its own (which will be published in due course).  In the meantime, if you have any questions, we’ll be happy to answer them on site. 

There you go:  now you also know the basic mistakes which we see too often.  The customer, who has no technical knowledge is completely in the hands of his/her installer and we therefore urge you to ensure your hard-earned money is not spent on a fence that cannot do what you need it to and what you’ve paid for.

Electric Fences:  Does it really work?  (Part 2 of 2)

Electric Fences: Does it really work? (Part 2 of 2)

Let’s pick-up where we left off in Part 1 of 2 (here is a link to the previous article: and again start with – Of Course electric fences work! Electric fences is a security measure to keep the bad guys out, or at least to provide you with plenty of warning (in the form of a 15 – 40 Watt siren going off) that somebody is trying to breach your perimeter security.

I dealt with the first 3 objections against electric fences and whether it works or not in my first article and now deal with the remaining 2:

1. Electric fences require too much maintenance; and
2. If the criminals really want to come in, you can’t stop them.

1. Electric fences require too much maintenance

I’m sure we’ve all seen those depressing electric fences with the fencing wire hanging loosely between brackets (some even broken completely with the ends hanging down the wall) and the brackets looking like it is on the verge of rusting and the fence just being a general eye sore to both the property and the neighbourhood.

The solution for this is very simple: ensure you use an installation company which does a professional installation and properly tensions your electric fence wire to ensure the wires do not sag. A professional installation company will use good quality products, so that your electric fence remains in good shape for years

The only care your electric fence does indeed require is to ensure it is kept clear of vegetation. Surely, this is not unlike mowing the lawn and generally keeping your garden neat? And in fact, yes, eventually a number of years after your installation (depending on the professionalism thereof) your electric fence will need to be re-tensioned with new springs and a few bobbins may need to be replaced here and there. This is something we do for a fraction of the cost of the actual fence and again any property has maintenance requirements from time to time. An electric fence will place undue responsibility on any property owner, which that owner does not already have. Especially if you use a professional installation company like Nelspruit Fencing.

2. If the criminals really want to come in, you can’t stop them

With as much respect as we can muster for this statement: yes, if someone is specifically targeting you and your property (almost like a hit!), you cannot really stop them. However, with this line of reasoning, why do you bother locking your front gate? We all do what we can to keep as safe as possible and to make it as difficult as possible for a criminal to enter your premises and if a criminal does manage it, to give you as much warning as possible to defend your loved ones and yourself. Electric fences are the best possible perimeter security with the best warning system – you just have to make sure it is installed properly and professionally.

At Nelspruit Fencing we take security serious and we’re happy to discuss all aspects of your electric fence and any other security system like perimeter beams with you. Contact us for your free quote in Nelspruit, White River, Barberton, Witbank, Lydenburg and Hazyview, 074 104 6028 / / Also, if you have any comments on this article, we’d love to hear from you and address any other objections or questions not dealt with in these articles.

Electric Fences:  Does it really work (Part 1 of 2)

Electric Fences: Does it really work (Part 1 of 2)

Simply put – Of course electric fences work! Security is a major topic of conversation in South Africa and at some point, in a conversation the question comes up “Do Electric Fences work?”. Our question to that is why do you think Electric Fences do not work?
It seems the following are the most common objections:

1. You can through a blanket over the electric fence and climb over it;
2. The electric fence does not always give an alarm when it is supposed to;
3. An electric fence gives too many false alarms (especially when it rains);
4. Electric fences require too much maintenance;
5. If the criminals really want to come in, you can’t stop them (my personal favourite).

Let’s deal with these objections one by one.

1. Throwing a blanket over the electric fence and climbing over it
This is laughably impossible to do without triggering the alarm. The electric fence wire is tensioned with springs and cannot support any person’s weight on it. If you put a blanket over the electric fence and push on the electric fence to climb over it, one of 2 things will happen:

(a) You will either break the spring and wire, which will trigger the alarm; or
(b) The top 2 wires will touch, which will trigger the alarm.

Additionally, what sort of blanket, which will not break the fence, will a person use to insulate himself against 10,000 Volts of electricity?

2. The electric fence does not always give an alarm when it is supposed to
If your electric fence does not give an alarm when 2 of the wires touch or one of the fence wires is cut, it means either that your installation was not done properly or that something is wrong and you need to contact a professional to check your fence.

There are 2 tests your electric fence installer can do, to show that your fence works. Please have a look at one of our earlier articles,, discussing these tests.

3. Electric fences give too many false alarms, especially when it rains
Again, if this is the case with your electric fence, it means either that your installation was not done properly, or something is wrong, and you need a professional to check your fence.

Some times, animals like a small lizard can cause false alarms if it climbs up a bracket and shocks itself to death when it is half-way on the bracket and half-way on a live wire. Unfortunately, it may then be stuck on the electric fence and causes a short, which will lead to false alarms.

While this is a great topic for me to discuss, I am on a word limit. Therefore, objections number 4 and 5 will be addressed in a follow-up article, which we will publish next week. If you can think of any other objections, please either comment on this article or email us at we’ll be happy to address any more objections.

Lastly (for now) if you are experiencing objection numbers 2 and 3 above, or would like a free quotation on a new electric fence, please contact us on 074 104 6028 / We provide free quotes in Nelspruit, White River, Barberton, Witbank and Lydenburg.

Security cameras – how do you know what you need?

Security cameras – how do you know what you need?

How do you know which security cameras to choose for your CCTV Surveillance System?  After all, there are many options to choose from.  Notably, one of the features to consider is the lens performance criteria of your security camera.  The lens size is directly linked to the reason you are installing a CCTV Surveillance System.

To clarify, the reason for your security cameras is for either, Detection, Observation, Recognition or Identification of the persons your camera can see.  Below is what each purpose means in terms of security cameras. 

  • Detection:  Meaning you will be able to detect movement in the area the camera is capturing. 
  • Observation:  Meaning you will be able to observe how people, animals or other objects are moving around in the area the camera is capturing.  This camera lens size is usually used in public parking spaces.    
  • Recognition:  Meaning you will be able to recognise a person you already know when you see him/her in the area the camera is capturing.    
  • Identification:  Meaning you will be able to identify strangers and read number plates on cars. 

It is very difficult to set a permanent rule saying an x mm lens automatically means you can identify up to y metres.  Due to the fact that there are other factors which impact on the distance of detail your security camera can see.  For example, the angle of installation will impact the distance of detail.  Also, a big lens which can identify at a large distance, may not be able to focus on something right in front of it.   Therefore, it is not enough to simply say you want a big lens. 

Obviously, the bigger your lens size, the more expensive your security camera.  Consequently, you need a professional company to provide you not only with the various options, but also to take the time to properly assess your site.  Nelspruit Fencing (Pty) Ltd will make recommendations to you so you, as the Customer and home or business owner, can make an informed decision regarding your needs.

Managing your CCTV Surveillance System

Managing your CCTV Surveillance System

CCTV Surveillance Systems are currently playing such a big role in the security industry, as a result, we are following up last week’s article with another one about CCTV.  You may wonder:  what is the point of having a CCTV Surveillance System, if you do not have/want a security guard who can constantly monitor your System?  The good news is that CCTV Surveillance Systems have evolved so much that it is no longer necessary to employ a security guard to monitor the system 24/7.  These days the CCTV Surveillance System does the monitoring for you and Nelspruit Fencing will make sure it is set-up in line with your needs.

First of all, it is not necessary to connect your cameras to a monitor designated only for use for the CCTV Surveillance System.  This is due to the fact that the cameras’ feeds in your CCTV Surveillance System can be viewed on your smartphone.  This is achieved by using the Smartphone App which all our CCTV Surveillance Systems have.  Consequently, all you need is Wi-fi at the premises where the cameras will be installed.

The CCTV Surveillance System will be set-up to record when it detects motion.  As a result, you will be able to view past recordings whenever you need to.  Furthermore, your Smartphone App can be set-up to send you notifications in the event it:

  1. Detects motion;
  2. Loses power; or
  3. Is being tampered with.

Due to these few basic steps a CCTV Surveillance System can be useful at any premise.  Of course, in addition to the notifications above, there are still numerous features and functions which you can choose from.  At Nelspruit Fencing will advice you of any additional features or settings which would be useful at your premises.

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.

Certificate of Compliance for Electric Fences – Find out more.

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
