You would probably be surprised if there was at least one enterprise or office without an entrance door. Indeed, the door is the simplest access control system that allows you to cut off strangers and control the entrance of “friends”.
In the modern world, ordinary doors no longer allow solving all the tasks facing the management and security service. Therefore, checkpoints of factories, office doors, and the interior of residential buildings are equipped with electronic security systems.
In fact, it does not matter what the barrier device is - a door with an electromechanical lock, a turnstile, a barrier or an automatic gate. All these are elements of the access control system (which can be look here ), allowing for various identifiers (cards, key fobs, access codes, biometric parameters of a person) carry out authorized admission to the protected areas of employees and guests. This is an electronic watchman who knows everything about everyone and clearly follows orders from his superiors.
Together with the software, the modern system allows you to flexibly configure security policies and access levels, keep electronic logs of reports on all events - passages, attempts at unauthorized access, emergency openings, etc. Advanced versions of the software automatically generate time sheets, allow you to calculate wages, keep records of offenders, and much more.
A modern access control system is an integrated hardware and software complex that helps to solve most of the accounting tasks and allows you to save money.
