Perimeter fence

A perimeter fence system is a fence that visually demarcates and protects a property by blocking entry at the property's perimeter. The level of protection offered varies according to the threat to the perimeter. Different types of perimeter fencing include:

Vertical bar fencing has been the most popular form of perimeter fence since the 1980s. In the 2000s, welded wire mesh and acoustic barriers have become popular. Vertical bar, acoustic barriers and welded mesh are used in commercial projects and landmarks and transport hubs.

Sensors may be attached to the fence that generate alarms when they detect someone cutting, climbing, lifting or otherwise bypassing the fence.
