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.
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.

Audio Alarm

The camera can create alarms on the basis of audio signals. You can configure signal strengths
and frequency ranges in such a way that false alarms, for example due to machine noise or
background noise, are avoided.
Notice!
i
First set up normal audio transmission before you configure the audio alarm here (see Audio).
Audio alarm
Select On if you want the device to generate audio alarms.
Do not use any special characters, for example &, in the name. Special characters are not
supported by the system's internal management.
Signal Ranges
You can exclude particular signal ranges in order to avoid false alarms. For this reason the
total signal is divided into 13 tonal ranges (mel scale). Check or uncheck the boxes below the
graphic to include or exclude individual ranges.
Threshold
Set up the threshold on the basis of the signal visible in the graphic. You can set the threshold
using the slide control or, alternately, you can move the white line directly in the graphic using
the mouse.
