ELECTRONIC FENCING
One just has to drive around any of the suburbs in our big
cities to discover that people have become obsesses with protecting
themselves against the invasion of crime, the have literally
fenced themselves in in an effort to prevent intrusion attempts.
No wonder then, that our society has found some relief in electronic fencing which can be installed on top of an existing
wall or as a stand-alone fence. The zone length, number of
wires and their distance are of some of the usual outlines
for these fences.
While some people are trying to keep certain elements out,
others are trying to find solutions to keeping their pets
in! Some dogs develop the habit of leaping over fences which
can cause somebody to get a nasty bite. This type of fencing
for dogs is known as invisible fencing as it is buried underground
around the area where the dog is confined. Metal prongs extend
from a small transmitter on the dogs collar and the transmitter
in turn responds to an electronic signal coming from the underground
wire. The dog is warned as it approaches the fence by a warning
beep, but if it ignores this and continues towards the fence,
he gets an electrical stimulus. An additional fence can also
be erected with the invisible fence as a means of security
and privacy.
Advantages of this type of fencing is that it
obviously requires less maintenance and is less expensive.
It does not apply to keeping people out; first of all most
people would object to wearing a collar and secondly electrical
stimulus would not be strong enough to deter the intruder
and provide a lethal Shock. The electronic fencing consists
of electric wires carrying high voltage electric pulses, but
robbers who are not wise to the workings of such a system
often tamper with the fence and its wiring which then triggers
off an alarm activation which is in turn transmitted to security
personnel.
Installing an electronic fence for riding schools can be
quite easy and can prevent terrible loss to the owners if
the horses were to bolt and jump ordinary fences. Proper grounding
will need three ground rods which ought to be copper-coated
for maximum efficiency. They will require a certain thickness
and should be placed about 3m apart from one another. Once
the rod system is in place it will have to be connected with
galvanized wire, with a ground rod clamp. Insulated cable
can also be used. If one just wraps the wire around the rod,
it will be a faulty connection. The energizer will compact
the electric current to provide a high-voltage pulse that
will be felt by a horse that touches the wire fence. Farmers
can make use of this type of electronic fencing in an effort
also to keep their live-stock in and predators out.
Electronic fencing has revolutionized the world we live in,
not only providing top security for ourselves, but looking
out for the safety of our pets as well.
