The must-see principle of access control system

[ Huaqiang Security Network News ] Modern access control systems have different functions in response to the needs of different customers in different locations. It also follows the principle of people-oriented and seeking truth from facts in design. In order to meet the management needs, different access modes may be required for the controlled gates. This can be achieved by the management rules (commands) provided by the system. The management rules mainly include: (1) Two-way control (PASSBACKCONTROL) The user must enter the code via the card reader or keyboard installed at the door to enter the security zone. Also, if you want to exit the security zone, you need to go through the device installed at the door exit. This type of control helps prevent multiple people from entering the security zone at the same time, and some of them do not register with the system, and also allow the system to track and report who is located in the security zone. Such a system can control the number of users in the security zone.
(2) Multiple control means that after allowing the user to enter the security zone, the password must be entered again on another keyboard to enter the strictly controlled internal area. This is used in situations where security is highly demanding.
(3) 2-PERSONACCESS-RULE requires two people to be present in the security zone or out of the security zone to enhance the security level of access control.
(4) The usage count control (USE-COUNT-CONTROL) specifies the maximum number of times each user can enter and exit. Once this maximum number of times is reached, the user will not be allowed to re-enter or the user will be deleted.
