Physical security cover means measures that prevent or deter
attackers from gaining entry to any facility or resource.
When electronic fences were first developed, the idea was
to restrict animal movement, but with the local criminal modus
operandi, it has became an overriding necessity to install
correctly fitted electronic fences, thus minimizing the chances
of criminals entering the premises, let alone making a quick
Wires are fitted on insulators and are powered by
an energizer which is capable of giving the would be thief
a most uncomfortable Shock. There are those that wish it were
more than just an uncomfortable Shock! The transformer converts
power to the person tampering with the fence but will not
kill as the system is designed to allow the power to work
on and off on a continuous basis; but the power is enough
to deter anyone trying to enter. If somebody tries to cut
the wires, an alarm will go off as a warning, which usually
means the person has not yet entered the premises, giving
people in the area time to re-act.
Most electric fences come
with an alarm. As with all security fences and gates, when
it comes to a life-saving device it is best not to try and
save money by going for cheap sub-standard equipment as this
leads to frequent replacing and your equipment being inactive
while being repaired. Good advice is to use your electronic
fence or wall to advertise the security measures you have
in place. Most security companies provide a metal board stating
that premises are protected by them. Visible security is a
definite deterrent. Making sure that your premises are well
illuminated at night can be an added security measure.
Electronic fencing is not only used exclusively for private Homes and business properties. Ships are known to have a 9000
volt electronic fence installed to keep out intruders as well
as to prevent pirate attacks. Stowaways will find it difficult
to by-pass such a voltage.
Pets, like dogs as well as horses and wild life are well
restrained within the boundaries of an enclosure or park with
electronic fencing, and once they have been exposed to the Shock, the fence actually becomes a psychological deterrent.
Underground fencing, known as invisible fencing, is more effective
for smaller animals such as dogs and cats and this is where
the wiring is placed underground and the animal's collar responds
to that wiring.
With the increase of crimes against children and youth in
schools, which includes kidnappings and paedophilia, more and
more parents are becoming alarmed at the fact that this once
safe place of learning for young people is now becoming a
breeding place for abuse and other crimes. Nursery schools
as well as schools for primary and high school children are
having to spend thousands of rands to secure the safety of
their pupils and educators by installing electronic fences as a means of keeping these elements out.
