Hi, I'm trying to get VCA informations like object tracking, motion, and tamper detection from Bosch Camera using its SDK, but couldn't find any code example or any explanation about how to do it with SDK. Can you help me, please?


What I have tried:

I've searched a lot and read its sample application in SDK folder but it doesn't have anything for VCA options like it has in "Configuration Manager" software.

You should talk to the people who created it - Integration tools | Bosch Security and Safety Systems I Nordics[^] - they should provide technical support and will know more about their product than we will. If they don't, then find another supplier and demand your money back!
   
This is from the Bosch Video SDK5 help file:
Quote:
VCA Overlay and VCA Configuration
Concept
All VCA related actions are handled through the IVcaConfig interface of the VCA configuration object that each video renderer provides with its ICameo::VcaConfig property. Before VCA overlay or configuration can be used, a live or recorded video stream has to be assigned to the cameo, see live video and media database replay.

VCA initialization
Register an event handler on the event _IVcaConfigEvents::StateChanged and call IVcaConfig::Initialize. The VCA algorithm is initialized when the state becomes vcsInitialized.

Enable VCA overlay
VCA overlay can be enabled for a cameo video renderer by setting the IVcaConfig::DisplayMode to 0x000000FF. No VCA algorithm ID has to be selected with IVcaConfig::AttachPlugin, the overlay rendering component is able to render video content data from all available VCA algorithms. Setting the display mode back to zero disables VCA overlay.

Show or edit a live configuration
For live configuration handling, a live video stream must be assigned to the cameo. Select the appropriate VCA algorithm ID by calling IVcaConfig::AttachPlugin with IVcaConfig::ViprocId as parameter ViprocID and zero as parameter PluginID. When the event _IVcaConfigEvents::StateChanged sends the state vcsAttached, download the device video input's current configuration with IVcaConfig::DownloadConfiguration and wait for the _IVcaConfigEvents::StateChanged event with state vcsOnline. Then set the IVcaConfig::DisplayMode appropriately to either show or edit the configuration. A modified VCA configuration can be send to the device by calling IVcaConfig::UploadConfiguration, an upload is finished when the state becomes again vcsOnline.

Show or edit a stored configuration
Stored VCA configurations can be either retrieved with a VCA configuration media database search as IVcaConfigData objects or have to be provided directly by the client application. Select the appropriate VCA algorithm ID by calling IVcaConfig::AttachPlugin with IVcaConfigData::ID as parameter ViprocID and zero as parameter PluginID. When the event _IVcaConfigEvents::StateChanged sends the state vcsAttached, set the IVcaConfig::Configuration buffer directly. Then set the IVcaConfig::DisplayMode appropriately to either show or edit the configuration. If the configuration has been modified, it can be retrieved afterwards with IVcaConfig::Configuration.

VCA Uninitialization
If a VCA algorithm has been selected with IVcaConfig::AttachPlugin it has to be released with IVcaConfig::AttachPlugin(0, 0, 0, ""). The VCA configuration object itself has to be uninitialized with IVcaConfig::Uninitialize before the cameo can be released.
