Door Access Control System

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
