In building perimeter access control, how is the defined area typically identified?

In building perimeter access control, the defined area is typically identified by the exterior of the building. This approach ensures that the controlled access point is clearly delineated, allowing security personnel to monitor and manage who enters or exits the premises effectively. The building's exterior serves as a natural boundary that outlines the property and can be easily recognized by individuals, making it an ideal reference point for establishing access control measures.

Using the exterior of the building helps in determining the most effective placement of access control systems and monitoring equipment, which enhances the overall security strategy. This method aligns with best practices in security management, where operational areas are clearly defined, and access is controlled based on physical boundaries that are obvious to both the security team and the general public.
