Door-access control system is
basically a physical security system designed to ensure the security of
a room or building by restricting unauthorised access to that room or
building. The system is so designed that it allows access to specific
people to that area and also keeps records of those accesses.
How the System Works?
- The system utilizes an individual-authentication method for
restricting access to specific people.
- Many different methods are used for limiting access to a room or
building through door access control systems.
- The most commonly used authentication method for door access
control system is based on smart cards. In such a system, only those
people can enter a room who have an allocated smart card with them.
However, the system creates some inconvenience in case the smart
card is lost.
To overcome this, yet another method of door access control has
been developed based on biometric identification. In this method, the
fingerprints of individuals are used as the main biometrics method for
individual authentication. This latest development marks the beginning
of the practical application of door-access-control systems utilizing
biometric data.
Advantage of Door Access Control Systems
These door access control systems are highly advantageous and offer
cost-effective means of security. These systems enable you to control
more than one door in a networked system. The system also facilitates
operating some doors in networked systems from a remote location, from
another room or even from around the world.
Application
Door access control systems are widely used worldwide for limiting door
access. Some of the areas where they are commonly used are:
- Residential Apartments
- Airports
- Civil Transportation
- Business Organizations
