What is Access Control?

Access control refers to the practice of restricting entry to a property, building, or room to authorized individuals. 

A human can achieve physical access control through mechanical means such as locks and keys or technological means such as access control systems like the mantrap. 

Key management may also be used to manage further and monitor access to mechanically keyed areas or access to certain small assets within these environments.

Physical access control is a matter of whom, where, and when. A security system controls who are allowed to enter and exit, where they are allowed to exit or enter, and when they are allowed to enter or exit.

Historically, this was achieved through keys and locks. Only someone with a key can enter through the door, depending on how the lock is configured. 

It is impossible to restrict the key holder to specific times or dates with mechanical locks and keys. 

Keys and mechanical locks do not provide a record of the key used on any specific door, and the keys can be easily copied or transferred to an unauthorized person.

Electronic access control relies on computers to overcome the limitations of mechanical locks and keys. 

A variety of credentials are available to replace mechanical keys. The electronic access control system allows access based on the credentials presented. 

Upon authorization, the door is unlocked for a predetermined time, and the transaction is recorded. 

When access is denied, the door remains locked, and the attempt to gain access is recorded. The system will also monitor the door and notify you if it is forced open or held open too long after being unlocked.
