Perimeter security refers to the measures taken to secure the boundaries of a property or facility, such as a building, campus, or government facility. This can include a range of security measures, such as fences, gates, walls, cameras, and security personnel. The goal of perimeter security is to prevent unauthorized access, deter criminal activity, and protect the property or facility from external threats such as theft, vandalism, or terrorism. Perimeter security measures may be designed to be visible and deterrent, or they may be designed to blend in with the surrounding environment. Perimeter security plans may be developed by the property owner, facility management, or a professional security company, and they may take into account factors such as the size of the property, expected level of security risk, and accessibility requirements. Perimeter security may be integrated with other security measures, such as access control and video surveillance, to provide a comprehensive security solution
