Motion detector
Select On to activate the video sensor.
Select sensor field
You can select the areas of the image to be monitored by the video sensor. The video frame is subdivided into
396 square cells. Each of these cells can be activated or deactivated individually. If it is necessary to exclude
particular regions of the camera field of view from the monitoring process due to continuous movement (a tree
moving in the wind, etc.), the relevant cells can be deactivated.
– Click Select area to configure the sensor cells. A new window will open.
– If necessary, click Clear all first to clear the current selection (cells marked in red).
– Left-click the cells you would like to activate. Activated cells are marked in red.
– Click Select all if you want to select the entire video frame for monitoring.
– Right-click any cells you wish to deactivate. "Inactive" cells are marked in white.
– Click Set to save the configuration.
– Click the close button (X ) in the window title bar to close the window without saving the changes.
Local sensitivity
The basic sensitivity of the video sensor can be adjusted for environmental conditions. The sensor reacts to
variations in the brightness of the video image. The darker the observation area, the greater the value that must
be selected in this field.
– Adjust the sensitivity by dragging the scroll thumb to the desired setting.
Average [n frames]
It is possible to define the number of frames in which movement must be detected in order to generate an
alarm. This can help prevent false alarms from events such as birds flying through the surveillance area.
– Select the desired value by dragging the scroll thumb to the appropriate position.
Object min size [n*n blocks]
You can specify the number of sensor cells that a moving object must cover to generate an alarm. This can
prevent small objects from triggering an alarm.
A minimum value of 2 (2 × 2 sensor fields) is recommended.
– Select the desired value by dragging the scroll thumb to the appropriate position.
Alarm indicator
To prevent false alarms, a threshold can be applied to the motion signal. This allows effects such as the
background noise from the camera itself to be filtered out.
The blue line in the Alarm indicator section represents the alarm threshold. Any value above its level will trigger
an alarm. The parts of the motion signal line which will cause an alarm are shown in red. The alarm threshold
can be set higher or lower to suit your needs.
– Observe the amplitude of the displayed movement signal over a longer period of time under all the lighting
conditions that may be encountered.
– Move the pointer over the blue line.
– Clcik and drag the line to the desired level.
