    How to export video including Video Analytics meta data?

    Exporting video with Video Analytics meta data is very useful in the process of optimization of Video Content Analytics performance. One could configure VA, record particular scene and then replay this scene over and over again using different VA configurations.

    Moreover the video could be exported and replayed multiple times with different VA configuration settings.

    This article describes the different possibilities - BVMS Operator Client and BVMS Viewer, VRM eXpport Wizard, Web Interface of a Bosch Camera. The choice of the tool depends on the way the camera and recording are managed. 

    • Camera that is managed by non Bosch Video Management System (also no VRM recording), or is not recording - Camera Web Interface
    • VRM recorded video - VRM eXport Wizard, BVMS Viewer
    • Camera that is managed by Bosch Video Management System -  BVMS OC, BVMS Viewer. 

    Note: Forensic search makes possible to search the meta data of the recorded video and select the relevant export stamp. Forensic search is part of BVMS OC and BVMS Viewer

    Important:

    The exported / recorded videos can be imported in BVMS OC 10.01. There it is possible to edit the VA Task settings for this particular export and to search the video for alarms. In that way is possible to apply different VA settings to the same video export, compare the results and find the optimal VA settings for the particular scene.
