Anti-passback Settings
To avoid some persons following users to enter the door without verification, resulting in security
problem, users can enable anti-passback function. The check-in record must match with check- out
record so as to open the door.
This function requires two devices to work together: one is installed inside the door (master device), the
other one is installed outside the door (slave device). The two devices communicate via Wiegand signal.
The Wiegand format and Output type (User ID / Badge Number) adopted by the master device and
slave device must be consistent.
