Door access control is a matter of whom, where, and when. An Access Control System determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit.

Electronic central door and access systems use computers to solve the limitations of mechanical locks and keys. A wide range of methods can be used to replace mechanical keys. You can use a swipe card, a password entered on a keypad, key fobs, or even biometric scanning to open your doors.

The main objective of a multi-access control system is to give quick and convenient access to authorized people into your remote sites, while also preventing the access of unauthorized people.
