environmental conditions to which the camera is subject. The
sensor reacts to variations in the brightness of the video image.
The darker the observation area, the higher the value that must
be selected.
Minimum object size
Specify the number of sensor fields that a moving object must
cover to generate an alarm. This setting prevents objects that
are too small from triggering an alarm. A minimum value of 4 is
recommended. This value corresponds to four sensor fields.
Debounce time 1 s
The debounce time prevents very brief alarm events from
triggering individual alarms. If the Debounce time 1 s option is
activated, an alarm event must last at least 1 second to trigger
an alarm.
Selecting the area
Select the areas of the image to be monitored by the motion
detector. The video image is subdivided into square sensor
fields. Activate or deactivate each of these fields individually. To
exclude particular regions of the camera's field of view from
monitoring due to continuous movement (by a tree in the wind,
for example), the relevant fields can be deactivated.
