Access control refers to any method used to regulate entry or exit from an area. A standard lock with a brass key can be considered a basic form of an access control system.
Over time, access control systems have become increasingly sophisticated. Nowadays, “access control system” typically refers to a computer-based, electronic card access control system. This system uses a special access card instead of a brass key to grant entry into secure areas.
In this context, “access control system” specifically means an electronic card access control system.
These systems are most commonly used to manage entry through exterior doors of buildings but can also control access to specific areas within a building’s interior.
The primary goal of an access control system is to provide quick and convenient access for authorized individuals while restricting entry for unauthorized persons.
The basic components of an access control system include an access card, access controller, reader, lock hardware, and an access control server/computer.
