Please follow the steps below to set up the camera tamper detection function:

1� Check Enable camera tampering detection�

2. Enter the tamper trigger duration. (10 sec. ~ 10 min.) The tamper alarm will be triggered only

when the tampering factor (the difference between current frame and pre-saved background)

exceeds the trigger threshold�

configurations in Event -> Event settings -> Trigger. For example, when the camera is

tampered with, camera can be configured to send pre- and post-event video clips to a

networked storage device� Please refer to page 111 for detailed information�
