Motion Detection
You can select the image areas to be monitored by the video sen-
sor. The video image is divided into 242 square cells. You can acti-
vate or deactivate every one of these cells. For example, if you want
to exclude certain areas in the field of vision of a camera from the
monitoring because there's continuous motion in that area (trees in
the wind), deactivate the corresponding cells.
In order for the video sensor to function, the following conditions
must be satisfied:
z
The motion detection must be activated.
z
At least one cell must be activated.
z
The sensitivity must be set to a value greater than zero.
z
The master alarm may also have to be activated.

Attention!
The basis for the video sensor is always the video image displayed
on the live image page. You therefore do not need to switch over
the image after activating the video sensor (another camera or
quad split), as the complete change of the image content would
immediately trigger the alarm.
Light reflections (e.g. in glass facades) or changes in light due to
individual clouds in bright daylight can result in undesirable reac-
tions of the video sensor and thus in false alarms. Carry out suffi-
cient tests to ensure the correct function of the video sensor.
For surveillance of indoor areas, ensure a constant lighting of the
areas during the day and at night.
