Access control â€” considered the first line of defense in facility security â€” often implies a sophisticated and computer-managed, multiple-door, integrated security system. A more common access control application, however, is a stand-alone system.
Even though a stand-alone system is not continuously connected to a host system, it still allows authorized individuals to get in and out of a building or an area within a building. Some of the most frequently used devices are key locks, mechanical push-button locks and electronic locking systems.
Bridging the gap between electromechanical locks and high-end systems are stand-alone card reader entry systems. Such systems can usually provide audit trail capability and some integration potential with video surveillance and alarm systems.
