What is Access Control?

Access control is focussed on controlling who has access, e.g. to an office or facility. This is typically achieved by restricting access by certain types of groups or access levels. With access control visitors, employees, executives, freelancers or employees can easily and securely access.
There are different fields of access control such as network access control, web-server access control and standalone access control. Unlike open access, access control provides control and security to address security and convenience to keep your business running securely.

Normal management of the Access Control are 'One for One', that means one card reader control one door. Valid card can open the door, 

invalid card can not open. But we can found that in many fields, a 'One for More Controllers' are needed.

Example 1: Lift Access Control Management

We usually have ten or more floors in one lift, but you just need one card reader. The system can distinguish the user's privilege, 

then take them to the right floor.

If the user has multi-floor privilege, when swiping the card, he can choose the floor he want to go this time, 

and he can not push other floor buttons.

If the users are the security and administrator, they can go to any floor they want according to the privilege settings.

Here are all available powerful functions for our ACB-DT20 and ACB-DT20K
