5.23.1 Analysis
Select the option On to activate the video content analysis.
As soon as the video content analysis is activated, metadata are created. 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 will be marked with
rectangles.
5.23.2 Analysis type
Select the required analysis algorithm. By default, only MOTION+ is available – this offers a
motion detector and essential recognition of tampering. The current alarm status is displayed
for information purposes.
5.23.3 Motion Detector (MOTION+ only)
For the detector to function, the following conditions must be met:
– 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.
5.23.4 Sensitivity (MOTION+ only)
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.
5.23.5 Minimum object size (MOTION+ only)
You can specify the number of sensor fields that a moving object must cover to generate an
alarm. This is to prevent objects that are too small from triggering an alarm.
A minimum value of 4 is recommended. This value corresponds to four sensor fields.

NOTICE!
On the Livepage Configuration page, you can also enable additional information overlays for
the LIVEPAGE (see Section 5.32 Livepage Configuration, page 85).
i
NOTICE!
Additional analysis algorithms with comprehensive functions such as IVMD and IVA are
available from Bosch Security Systems.
If you select one of these algorithms, you can set the corresponding parameters here directly.
You can find information on this in the relevant documents on the product CD supplied (see
Section 3.1 Scope of Delivery, page 11).
!
CAUTION!
Reflections of light (off glass surfaces, etc.), switching lights on or 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.
