@HyobinPark-AIVN you could try using axis metadata to look if these changes reflected in metadata stream, if yes websockets could be used. |

In the web UI text overlay, I can place '#lv', '#z', '#Z'. but it seems #lv reflects zoom change and '#z' '#Z' do not update when I change zoom rate.
Why is '#lv' the only modifier that reflects zoom change, whereas '#z' and '#Z' do not update?
and is there a supported VAPIX or WebSocket endpoint to retrieve the current focal length in real time?
