Access Control System (ACS) is a set of software and technical security tools that provide restriction and registration of the entry and exit of objects (people, vehicles) in a given area thru the access points: doors, gates, checkpoints.
The main task of the access control system is to provide control of access to a given territory: who, when and where is let to pass, including the identification of persons and / or vehicles. In addition, the access control system helps to solve work time logging tasks. It can also be integrated with accounting, personnel management, video surveillance, security and fire alarm systems.
In order to provide additional security for access control at critical facilities, the network of access control devices is installed physically separate from other information networks.
