The Face Recognition clock may take multiple punches if a user stands in front of the clock for too long. To prevent this, you can set the clock to reject any punches made within a short period of time.


Dup. Punch Period (m): If a user’s attendance record already exists and the user punches in again within the specified period (unit: minute), his/hersecond attendance record will not be stored. (Value scope: 1─60 minutes). Recommended value: 5 minutes.
