12.2.2
Analysis type
Select the required analysis algorithm. By default, only Motion+
is available — this offers a motion detector and essential
recognition of tampering.
Metadata is always created for a video content analysis, unless
this is explicitly excluded. Depending on the analysis type
selected and the relevant configuration, additional information
overlays the video image in the preview window next to the
parameter settings. With the Motion+ analysis type, for
example, the sensor fields in which motion is recorded are
marked with rectangles.
12.2.3
Motion detector
Motion detection is available for the Motion+ analysis type. For
the detector to function, the following conditions must be met:
–
–
–
–
Note:
Reflections of light (from glass surfaces, etc.), lights switching
on and off, or changes in the light level caused by cloud
movement on a sunny day can trigger unintended responses
from the motion detector and generate false alarms. Run a
series of tests at different times of the day and night to ensure
that the video sensor is operating as intended. For indoor
surveillance, ensure constant lighting of the areas during the
day and at night.
Sensitivity
Sensitivity is available for the Motion+ analysis type. The basic
sensitivity of the motion detector can be adjusted for the
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.

Analysis must be activated.
At least one sensor field must be activated.
The individual parameters must be configured to suit the
operating environment and the desired responses.
The sensitivity must be set to a value greater than zero.
