The term access control refers to permitting entrance to a property, a building, or a room to authorized persons only using related access control devices & methods. Mechanical access control is achieved using locks and keys etc. But such access control mechanisms are completely outdated due to serious disadvantages of not being able to provide any time-controlled access, not able to generate any access control logs and reports.
Physical access control is a matter of who, where, and when is allowed or denied access. An access control system determines who is allowed to enter or exit, where & whern they are allowed to exit or enter. Electronic access control uses advanced electronics & software to eliminate the limitations of mechanical locks & keys. Today, wide range of credentials and authentication options are available to replace mechanical keys. The electronic access control system grants access based on the credential presented. These credentials can be a PIN, Biometric, multi-credential combinations etc. When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is declined, the door remains locked, and the attempted access is also recorded. The system also has advanced functionalities that enable users to monitor the door and alarm if the door is forced open or held open too long after being unlocked.
