Motion detector
The camera contains an integrated video sensor, which on the basis of the video processing
can register changes in the video signal. These changes are primarily initiated by movement in
the field of view of the camera. The sensitivity of the video sensor can be adjusted, so that an
alarm is generated only if a given threshold is exceeded. In order for the alarm to operate, the
following conditions must be fulfilled:
¾
the motion detection must be activated.
¾
at least one cell must be activated.
¾
individual parameters must be matched to the environmental conditions and to the
required responses.
¾
the sensitivity must be set to a value >0.
Light reflections (e.g. in glass facades), switching on or off of floodlights 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.
Motion detector:

On
to activate the video sensor.
Select sensor field:
the areas of the image to be monitored by the video sensor are
selected here. The video frame is subdivided into 396 quadratic
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
movement (e.g. due tree movement in a wind), the relevant cells
can be deactivated (use mouse click for this operation)
Local sensitivity:
the basic sensitivity of the video sensor can be adapted for the
ambient camera conditions. The sensor reacts to brightness
variations in the video image. The darker the observation range,
the greater the value that must be selected here. Adjust the
sensitivity by moving the slider to the desired setting with the
mouse key held down.
Average n [frames]:
it is possible to define the number of frames during which a
movement is monitored in order to generate an alarm. In this way,
