How does a security fence contribute to physical security?

A security fence is a critical component of physical security because it establishes a clear and tangible boundary that prevents unauthorized individuals from entering a secure area. By doing so, it creates a significant psychological deterrent; the very presence of a fence indicates restricted access, which can discourage potential intruders from attempting to breach the perimeter.

While surveillance capabilities are important for monitoring activity, a fence does not inherently provide those capabilities unless integrated with surveillance technology. Similarly, although emergency services require access, a fence is primarily designed to maintain security rather than facilitate movement. Controlling vehicle access is another important aspect of security, but a fence serves a broader purpose by protecting the entire perimeter rather than just controlling vehicles. Therefore, establishing a physical boundary that deters unauthorized access is fundamental to the role a security fence plays in enhancing physical security.
