102 en | Configuring the IP AutoDome VG4 Modular Camera System
F.01U.133.268 | 6.0 | 2010.03 User’s Manual Bosch Security Systems, Inc.
Audio
Select the On option if you wish to additionally transmit a standalone G.711 encoded audio
stream with alarm connections.
10.45 Advanced Mode: VCA
The IP AutoDome contains an integrated video content analysis (VCA), which can detect and
analyze changes in the signal using image processing algorithms. Such changes can be due to
movements in the camera's field of view.
You can select various VCA configurations and adapt these to your application as required.
The Silent MOTION+ configuration is active by default. In this configuration, metadata is
created to facilitate searches of recordings; however, no alarm is triggered.
You can switch off the video content analysis completely if the device's full power is to be
made available for the encoder.
1. Select a VCA configuration and make the required settings.
2. If necessary, click the Default button to return all settings to their default values.
10.46 Advanced Mode: VCA Profiles
You can configure two profiles with different VCA configurations. You can save profiles on
your computer's hard drive and load saved profiles from there. This can be useful if you want
to test a number of different configurations. Save a functioning configuration and test new
settings. You can use the saved configuration to restore the original settings at any time.
1. Select a VCA profile and enter the required settings.
2. If necessary, click the Default button to return all settings to their default values.
3. Click the Save... button to save the profile settings to another file. A new window is
opened, in which you can specify where you want to save the file and what name you
want to save it under.
4. Click the Load... button to load a saved profile. A new window opens in which you can
select the profile file and specify where to save the file.
VCA configuration
Select one of the profiles here to activate it or edit it.
You can rename the profile.
1. To rename the file, click the icon to the right of the list field and enter the new profile
name in the field.
2. Click the icon again. The new profile name is saved.
NOTICE!
In the default setting, Stream 2 is transmitted for automatic connections. Bear this fact in
mind when assigning the profile (see Section 10.16 Advanced Mode: Encoder Profile, page 78).
NOTICE!
If computing power becomes short, the highest priority is always the live images and
recordings. This can lead to impairment of the video content analysis. You should therefore
observe the processor load and optimize the encoder settings or the video content analysis
settings as necessary.
