Perimeter management, especially in the management of the airport perimeter has long been plagued by security vendors and integrators, airport users. The so-called perimeter, as the name implies is surrounded by the defense of a specific area, also commonly called the enclosures. Surrounded by a region of many ways the ancients moat, today's roll mesh, barbed wire are the most common physical enclosures, these basic means of perimeter protection already can not meet the security needs of some specially places, how to apply the new technological means to make the the the traditional physical Wai sector development of the ability to become active defense and alarm, and the alarm is accurate and effective.

Problems faced by the airport perimeter security

       Today, a lot of civil construction in the use of the electronic fence very cost-effective products to achieve a perimeter alarm management and prove that it is the most effective and most direct practical application, but why the airport's perimeter alarm so plagued users and manufacturers do? Let's take a look at the characteristics of the airport perimeter. Airport perimeter in addition to the the general civil perimeter pervasive characteristics, there are still other characteristics, such as the perimeter of a large range, anywhere from ten kilometers, more than a few tens of kilometers; followed by an empty side is often Yimapingchuan to the vast horizons, but It is precisely because a lot of the empty side of the airport outside the perimeter of desolate; the last airport quite a lot of visual, physical perimeter fence, many airports in the roadside with a barbed wire design. Three characteristics actually brought three quite interesting difficulties,

       First, the long distance cause the artificial the patrol field or out of the police in a timely manner after the alarm difficulty;

       Second, the vast flat terrain makes the intruder once the blockade after a short time a second measure to restrictions on movement;

       Third, barbed wire appearance deficiencies, and long hours of sunshine and rain cause barbed wire surface rusting, corrosion, brittle.

       According to statistics, from 2004 to 2007, China has successively occurred a few aircraft "illegal immigration" event "illegal immigrants" who do not know God hesitate to enter the apron, climbed into the aircraft's right landing gear pod The one success of "illegal immigrants" from Kunming to Chongqing, when the plane took off, another person tripped and fell to his death. Several incidents occurred, also led to a high degree of concern for the prevention of the airport perimeter.

The role of the electronic fence of the airport perimeter to prevent

       In recent years, the airport's perimeter to prevent more and more attention, many airports have construction or start building a perimeter alarm system. For example, the Shenzhen Airport deployed around the airport for up to twenty thousand meters of the electronic fence. Electronic fence electronic fence perimeter to prevent other perimeter to prevent product irreplaceable advantages have gradually become the product of choice in the construction of the airport perimeter. Deterrence and effectively block is the root cause of the electronic fence is accepted by the public. When someone tries to climb the electronic fence to enter the airport internal electronic fence will be hit with pulse current, repel intruders and alert, and police intelligence fed back to the control room to inform the security personnel, the exact location of the point of the invasion, security can quickly reach the invasion point to deal with the police intelligence. Thereby leading to the occurrence of blocking all negative factors from the roots up, to take preventive measures, this is the electronic fence biggest role.
