    Hi Mohamed,

     

    Could you please elaborate if the object tiles are missing from the Objects tab while you are watching live video from the camera? If so, could you please check if all the objects are shown during archive playback? Do you see the bounding boxes of the objects while not seeing their tiles in the Objects tab, or both bounding boxes and object tiles from the Objects tab are missing?

    My wild guess is that the metadata packets from the plugin are coming with a feasible delay sometimes, and in this case you are not able to see the object tiles in Right Panel in llive mode. But you still should be able to see these objects in the archive.

    Hello Zendesk,

    your guess is right. could you explain what is archive? where it's available? How to view that? I don't have any idea about archive. But, I often see this on many posts.

    Hi Mohamed,

    By archive we mean the video footage that was recorded by the Mediaserver. It is stored on a disk(-s) that you can select as a recording storage via "Server settings" menu. The archive is basically stored on that disk(-s) as MKV files in a folder named "Nx MetaVMS Media".

    So, when you enable recording for a camera, your Server is starting to record the archive.

    By watching the archive we normally mean playing the recorded video via Desktop Client.

    What I was suggesting you to do is to check if the objects that are missing and not shown in the Client are shown later when you play the recorded video for the same time period. If it really is so, than there is a strong possibility that your plugin is sending the metadata with outdated timestamps - the Client is unable to show it when you are watching live video because the Client is already showing the frames with newer timestamps. But this metadata is still going to be recorded to the DB, and when you're watching the archive (watching the recorded video) the corresponding objects are going to be shown.

    Hope this will make things a bit more clear.

    Hello NX Team,

    As you mentioned, I have tried downloading archive files using recordedTimePeriods and Direct download APIs. Using the above API, I successfully downloaded video files. when I look into the video, I am not getting any bounding boxes. If I am not wrong, I should get bounding boxes on object in the video. please let me know if you need any further information.

    Hi Mohamed,

    The bounding boxes arre visible when you play the recorded video via Desktop Client. You do not need to export the video from the video Server via direct download or any other means to watch the recorded video with bounding boxes, you can simply play it from Desktop Client.

    On the countrary, when you export the recorded video and then play it (BTW, which player do you use?), you are not going to see any bounding boxes, only the video is going to be shown.
