Common access control systems include: Password entrance guard system, non-contact IC card inductive IC card entrance guard system, fingerprint iris zhang the floorboard of the type of biometric access control system, etc. The weak password entrance guard system due to its own security and convenience are facing elimination, biometric access control system security is high, but the cost is high, because the application such as false reject rate and storage capacity bottleneck question without recognition widely market. Now the most popular the most generic or non-contact IC card entrance guard system. The non-contact IC card due to its higher security, The best convenience and cost performance have become the mainstream of the access control system. Below we mainly introduce the non-contact IC card access control system.

Part of the access control system?

The access control system consists of the access control controller card reader, the outgoing button communication hub, the induction card management software.

Remark:

The above is an integral part of the networked access control system.

Some access control integration opportunities integrate the reader and the controller together, so that the security will be reduced and the cost will be reduced because the control part is exposed.

Some strict management in and out of the entrance guard system, can use another card reader instead of push button and the two-way read card entrance guard system, such not only can enter human rights management, can management out of permissions, and record the in and out of the record. The higher security level. Also some entrance guard system card reader is with password keyboard function, in not only the requirement accord with through the identity card, and must input the password, so that even if the card was found to fall into.

Biometric access control system refers to the access control system that replaces the card reader with the fingerprint reader, iris device, palm type device, etc.

Communication hubs have two functions: increasing the distance between the controller and the computer, and connecting many control units.
