depending on the event type you want to receive, you can add eventtopic in the rtsp url to only receive some topic. refer to VAPIX for details: |

sorry for misunderstanding your question, you are using analytics=polygon to get the metadata, it seems the metadata will produce at 10 fps , so you can add filter in the callback to filter according to search ObjectId.
