The area anti-passback function establishes a specific door group for an area. When a person accesses the area by swiping card, he/she should exit the area via the door in the anti-passback group if he/she enters the area via the door in the group, and he/she cannot enter the area via the door in the anti-passback group if he/she exited the area not by swiping card at the door in the group before.
Add the access points to different areas first. For details, refer to Add Element to Area.
