Design and installation of electronic fence

1. The design of the electronic fence is equipped with appropriate electronic fences that meet the requirements according to different security levels. The security level is usually divided into three levels:

(1) Deterrent - There is a zone throughout the perimeter, such as a 4-wire system mounted on the top of the wall. Has a blocking alarm and deterrent effect.

(2) Medium security level. The length of each zone is not more than 300 meters, and more than 300 meters should be divided into multiple zones.

(3) High security level. The length of each zone is set at 100 meters and the entire fence is divided into multiple zones. Each zone has its own independent trigger alarm that indicates the zone in which the alarm is located. The alarm output is usually linked to other security systems such as CCTV, infrared radiation, spotlights, and alarms. In actual use, the length of each zone should be set according to length, terrain and economic needs.

2. The installation of the electronic fence is divided into three basic installation forms: independent, attached and wall-top according to the installation position at the site.

A freestanding electronic fence that is erected directly on the ground. Its height is about 2 meters, and generally 10-12 cables are installed. Considering the equipment and personal safety, it is required to install a protective wall or wall of not less than 1.2m on one side or both sides of the free-standing electronic fence. The clearance distance between them should be no less than 1m. The normal working area of ​​the freestanding electronic fence is placed in an enclosed area that is generally difficult for the public to access.

The attached electronic fence is attached to the fence, and the attached electronic fence is mainly used in places where there is a high level of safety and does not occupy the surrounding land. There are three requirements for the existing wall. First, the wall should have sufficient fastness to withstand the tension and pressure of the electronic fence. Second, the height of the wall should be no less than 2m. Third, the mesh of the wall must be less than 50mm to prevent human hand from reaching and touching the electronic fence attached to the inside of the wall. Wall-top electronic fences are more popular in China and are placed above or at the top of existing walls. It can be installed vertically or at a certain angle. The height of the electronic fence is about 0.8m.
