Network camera
Appearing edges
Select this option if the selected area of the reference image includes a largely homogenous
surface. If structures appear in this area, then an alarm is triggered.
Global change
Activate this function if the global change, as set with the Global change slide control, should
trigger an alarm.
Global change (slider)
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 Mask.... 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 detection, independently of motion alarms, manipulation of the orientation or location
of a camera resulting from turning the camera mount bracket, for example.
Current brightness
For information, the current brightness of the camera scene is displayed. The brighter the
scene, the higher the value. Use this value as an indicator when defining a corresponding
threshold.
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.
Use the slider to set the threshold of the alarm trigger.
Scene too dark
Activate this function if tampering associated with covering the lens (for instance, by spraying
paint on it) should trigger an alarm.
Use the slider to set the threshold of the alarm trigger.
