3.
Check the box
Reference check
to activate the on-going check. The stored reference
image is displayed in black and white below the current video image.
4.
Select the
Disappearing edges
or
Appearing edges
option to specify the reference check
once again.
Sensitivity
The basic sensitivity of the tamper detection can be adjusted for the environmental conditions
to which the camera is subject. The algorithm reacts to the differences between the reference
image and the current video image. The darker the observation area, the higher the value that
must be selected.
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.
Disappearing edges
The area selected in the reference image should contain a prominent structure. If this
structure is concealed or moved, the reference check triggers an alarm. If the selected area is
too homogenous, so that concealing and moving the structure would not trigger an alarm,
then an alarm is triggered immediately to indicate the inadequate reference image.
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.
