Door access control is a matter of who, where, and when. An access control system determines who is allowed to enter or exit, where they are allowed to enter or exit, and when they are allowed to enter or exit. This is partially done through keys and locks. When a door is locked only someone with a key can enter through the door depending on how the lock is set up. Mechanical locks and keys do not limit the key holder to specific times or dates.
Mechanical locks and keys do not provide records of the key used on any specific door and the keys can be easily copied or transferred to an unauthorized person. When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must be re-keyed.
Instead of Mechanical Locks and Keys
Electronic door access control uses computers to solve the limitations of mechanical locks and keys. A wide range of methods can be used to replace mechanical keys. Some kind of remote telemetry unit at each door location grants access based on the credential presented such as; password entered on a keypad, a swipe card used with a proximity sensor, or even biometrics. The decision can be made locally by the door unit, remotely by a central management system or cooperatively by sharing login profiles and access requests.
When access is granted, the door is unlocked for a set time and the event is logged. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked.
What Is An “Access Control System”?
Simply defined, the term “access control” describes any technique used to control passage into or out of any area. The standard lock that uses a brass key may be thought of as a simple form of an “access control system”.
Over the years, access control systems have become more and more sophisticated. Today, the term “access control system” most often refers to a computer-based, electronic card access control system. The electronic card access control system uses a special “access card”, rather than a brass key, to permit access into the secured area.
When used within this document, the term “access control system” refers to an electronic card access control system.
Access control systems are most commonly used to control entry into exterior doors of buildings. Access control systems may also be used to control access into certain areas located within the interior of buildings.
The purpose of an access control system is to provide quick, convenient access to those persons who are authorized, while at the same time, restricting access to unauthorized people.
We offer several options of protection by means of door access. Door locks and garage doors can be monitored and controlled using a remote sensing system. You can view, time, and control entry into your home on a schedule or through live activation via a remote device. Our custom features involve mobile apps that allow you to view and control this activity wherever you are.
