Access control is a security technique that can be used to regulate who can get access to the specified door and floor control can be used to regulate who can get access to the specified floors by taking the elevator.
On the Web Client, the administrator can add access control devices, elevator control devices, and video intercom devices to the system, group resources (such as doors) into different areas, and define access permissions by creating an access level to group the doors/floors and an access group to group the persons. After assigning the access level to the access group, the persons in the access group will be authorized to access the doors and floors in the access level with their credentials during the authorized time period.
