Door Reader & Access control System

Door access control has become a very vital part of your security structure. The door readers monitor the electric lock and determine who gets entry into the building.

The access control readers conduct credentials which can be cards that fit in your wallet, or thick lanyard cards with holes that can be put around your neck, or keyfobs that integrate with your keyring. The latest door readers can also open your door with your smartphone. The most secure credentials include your biometric attribute. Your face or fingerprint provides right identification of you rather than the credential you bear.


This article conveys how door access control systems functions


The Door Reader for Door Access:


The door readers with the help of credentials possess embedded circuits and an antenna. The reader transmits a signal that is received by the credential antenna. The transmitted electrical signal from the door reader carries enough power to energize the circuit in the credential. Once the electric circuit inside the credential receives the power it sends back a signal to the access control reader that contains its identification (ID) number.


The latest door readers are smart devices that link to the network. They have direct connection to the network and carry the identification codes for all the people assigned to the system. They can function even if the organization’s network is low and the central management software is unavailable. 


Door Reader Credentials for Door Access Control System:

The credentials appear with a unique internal number that identifies the card credential. You can choose the type of RFID credential you would like. For instance, the cards are thin, thick or of keyfob formats. Each credential carries a card number. There are also credentials that utilize various data formats and frequency between the credential and the door reader. 

There are also many other ways a door access control system works. The above mentioned article tells you about some of the credentials of the door access control system.

They are responsible for distributing the people around towards their specific destinations, thus regulating the flow of traffic entering and exiting the building. The efficiency of the elevators are therefore an important area of concern for the building managers. Modern buildings are integrated with lift access control systems that optimize elevator systems by allocating lifts efficiently according to the priority algorithm. This works miraculously in reducing wait times in the lobby.  The smart access control systems allow restricted access to specific floors at specific times. An ID can be assigned to employees who are granted access to the floor, depending on their shifts. The control panels of the lift systems also include CCTV cameras to observe unauthorized people at
