▓ Many government departments, commercial buildings or corporate
headquarters have strict management rules for visitors. The traditional solution is to have
security staff to register the visitor's identity, to manually manage the visitor's access area.
▓ In order to improve the efficiency and reduce the dependence on human, visitor access control system
is a kind of more effective and economical means of visitor management.
▓ Visitor access control system consists of three subsystems: visitor management system, access control
management system and passageway management system:
▌Visitor management system distributes corresponding authority by registering visitor's identity information.
▌Access control management system controls visitor's access area by identifying visitor's authority.
▌Turnstile is the carrier of passageway management system. It implements the demand of access control management
system and ensures orderly and controllable passing.
▓ Whether the whole system can reliably and quickly run depends on interaction of these three subsystems.
