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: https://www.nelspruitfencing.co.za/electric-fences-does-it-really-work-part-1-of-2/) 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.

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, https://www.nelspruitfencing.co.za/cut-wire-and-earth-short-test/, 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 sales@nelspruitfencing.co.za: we’ll be happy to address any more objections.
