VG4 Modular Camera System
Alarm status
The alarm status is displayed here for information purposes. This means you can check the
effects of your settings immediately.
Aggregation time (s)
You can set an aggregation time of between 0 and 20 seconds if necessary. The aggregation
time always starts when an alarm event occurs. It extends the alarm event by the value set.
This prevents alarm events that occur in quick succession from triggering several alarms and
successive events in a rapid sequence. No further alarm is triggered during the aggregation
time.
The post-alarm time set for alarm recordings only starts once the aggregation time has
expired (see Section 10.40 Advanced Mode: Recording Profiles, page 95).
Analysis type
Select the required analysis algorithm. By default, only MOTION+ is available – this offers a
motion detector and essential recognition of tampering.
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.
Metadata is always created for a video content analysis, unless this was 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
will be marked with rectangles.
NOTICE!
On the LIVEPAGE Functions page, you can also enable additional information overlays for the
LIVEPAGE (see Section 10.13 Advanced Mode: LIVEPAGE Functions, page 76).
Motion detector (MOTION+ only)
For the detector to function, the following conditions must be met:
–
–
–
–
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.
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.
Bosch Security Systems, Inc.
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.
