Electric gates
are an easy way to ensure the security of private premises and can be used for
all sized properties. Electric gates, though not very commonplace at the moment,
have found their niche in the market today. For those who find the security of
their premises (be it residential or commercial) important, electric gates are
the way to go. There is a decrease in the cost of electric gate kits and their
installation. Aside from the basic kits, there are now many features that can be
added to ensure security as well as make them more convenient.
The Electric Gate Motor
The backbone of any electric gate, whether automatic or not, is the electric gate motor, the electric device which actually enables the electric gate to open and close without having to manually push the gate. All types of electric gates and barriers make use of a motor of some kind. There are many different kinds of electric gate motors. They differ in design, power and use. Depending on the type of gate you have, the suitable electric gate motor will also differ.
Electric gates alone, however solid and imposing they may be, cannot guarantee a totally secure environment. Electric gates are recommended to be used in combination with other security features to install a full security system. A few of these features are closed circuits with security cameras, additional gates in conjunction with the main gate, electronic keycards and keypads, security guards.
Aside from the additional security features that should go with parking barrier gates electric security gates often offer safety features like sensors that determine when there is an obstruction to prevent the electronic gate from swinging into a vehicle or closing on somebody's hands. to prevent the electronic gates from being damaged by irresponsible drivers driving fast speed bumps are also commonly placed before gate entrances to slow down vehicles
Electric Fences
The concept of the electric fence was first described in Mark Twain's A Connecticut Yankee in King Arthur's Court, in 1889, as a defensive weapon. Electric fences were used to control livestock in the United States in the early 1930s, and electric fencing technology developed in both the United States and New Zealand.
An early application of the electric fence was developed in 1936–1937 by New Zealand inventor William "Bill" Gallagher Sr. Built from a car's ignition coil and a meccano set, Gallagher used the device to keep his horse from scratching itself against his car. Gallagher later started a company to improve and market the design ". In 1962, another New Zealand inventor, Doug Phillips, invented the non-shortable electric fence based on capacitor discharge. This significantly increased the range an electric fence could be used from a few hundred yards to 35 miles, and reduced the cost of fencing by more than 80%.[citation needed] The non-shortable electric fence was patented by Phillips and by 1964 was manufactured by Plastic Products, a New Zealand firm, under the name "Waikato Electric Fence. This idea was to move from ceramic to using a plastic insulator at the post. A variety of plastic insulators are now used on farms throughout the world today.
In 1969 a farmer, Robert B. Cox, in Adams County, Iowa, near Corning, Iowa invented an improved electric fence bracket and was issued a United States Patent No. 3,516,643 on June 23, 1970. This bracket improved electric fences by keeping the wire high enough above the ground and far enough away from the fence to permit grass and weeds that may grow beneath the wire to be cut down by a mower. The brackets attached to the posts by what may be called a "pivot bind" or "torsion-lock." The weight of the bracket, the attached insulator and the electric wire attached to the insulator bind the bracket to the post.
Electric fences have improved significantly since the early days. Improvements include:
- Polyethylene insulators replacing porcelain insulators, beginning in the 1960s. Polyethylene is much cheaper than porcelain and is not as breakable.
- Improvements in electrical design of the fence energizer, often referred to as a "charger" (USA) or "fencer" (UK).
- Changes in laws. In some jurisdictions, certain types of electrical outputs for fences were unlawful until the 1950s or 1960s. In other areas, signage requirements and other restrictions limited usability.
- Introduction of high tensile (HT) steel fence wire in the 1970s in New Zealand and in the 1980s in the United States
- Introduction of synthetic webbing and rope-like fencing materials woven with fine conducting wires.
