Reference check
Save a reference image that can be continuously compared with the current video image. If
the current video image in the marked areas differs from the reference image, an alarm is
triggered. This detects tampering that would otherwise not be detected, for example, if the
camera is turned.

Trigger delay [s]
Set delayed alarm triggering here. The alarm is only triggered after a set time interval in
seconds has elapsed and then only if the triggering condition still exists. If the original
condition has been restored before this time interval elapses, the alarm is not triggered. This
avoids false alarms triggered by short-term changes, for example, cleaning activities in the
direct field of vision of the camera.
Global change
You can set how large the global change in the video image must be for an alarm to be
triggered. This setting is independent of the sensor fields selected under Select Area. Set a
high value if fewer sensor fields need to change to trigger an alarm. With a low value, it is
necessary for changes to occur simultaneously in a large number of sensor fields to trigger an
alarm.
This option allows you to detect, independently of motion alarms, manipulation of the
orientation or location of a camera resulting from turning the camera mount bracket, for
instance.
Global change
Activate this function if the global change, as set with the Global change slide control, should
trigger an alarm.
Scene too bright
Activate this function if tampering associated with exposure to extreme light (for instance,
shining a flashlight directly on the lens) should trigger an alarm. The average brightness of the
scene provides a basis for recognition.
Scene too dark
Activate this function if tampering associated with covering the lens (for instance, by spraying
paint on it) should trigger an alarm. The average brightness of the scene provides a basis for
recognition.

Virtual Masks

Note: This section applies only to the visible camera.
Virtual masks allow users to mask parts of the scene which should not be considered for flow
analysis to trigger Intelligent Tracking. This allows users to mask background motion in the
scene such as moving trees, pulsating lights, busy roads, etc.
To create a virtual mask:
1. Select the number of the Virtual mask. In the video preview window, a dark grey rectangle
appears with the text "Mask x," where 'x' is the number of the mask.
