Physical Security and Perimeter control
-Access control systems allow authorized personnel and material to move through normal access routes while detecting and delaying movement of unauthorized
personnel and material.
-Access control adds little, if any, enhancement to a structure's physical barriers. The use of electrically operated locks and strikes with access control systems may actually reduce penetration delay times for doors.
-Thus, access control systems must be integrated with other components of the overall physical security system to be effective. This will ensure that personnel seeking entry to the protected area are queued at the control point(s).
-There are many different types of access control systems and they vary extensively in their complexity and capabilities.
