Warning!
Light reflections (e.g. in glass facades), switching on or off of flood-
lights or light level changes caused by cloud movement in bright
daylight can cause undesirable responses from the video sensor
and thereby generate false alarms. Carry out a number of tests for
different day and night time conditions in order to ensure correct
operation of the video sensor.
For surveillance of indoor areas, ensure a constant lighting of the
areas during the day and at night.
Uniform surfaces without contrast can trigger false alarms even
with uniform lighting.

The areas of the image to be monitored by the video sensor are
selected here. The video frame is subdivided into 396 square cells.
Each of these cells can be activated or deactivated. If it is
necessary to exclude particular regions of the camera field of view
from the monitoring process because of, say, continuous move-
ment (e.g. due tree movement in a wind), the relevant cells can be
deactivated.
Click on the button Select area, to configure the sensor cells. A
new window is opened up.
If necessary, click on the button Clear all first in order to clear the
current selection (cells indicated in red).

frame.
