Request to Disable Offline Camera Footage Looping and Clarification on Camera Status Detection

Planned

Hi Nx Team,

I wanted to ask if it’s possible to disable the feature where an offline camera periodically displays the last 2 seconds of footage?

The reason for this request is that we’re currently streaming footage from a camera directly into Nx (no recording), and then forwarding that stream to a video content analytics (VCA) engine, which is integrated back into Nx (with recording).

This setup allows us to view both the live footage and the analyzed footage within Nx. However, the VCA engine appears to interpret the periodic display of the last 2 seconds of footage as the stream being online, which results in Nx incorrectly showing the analyzed stream as online, when passed back, even when the camera is actually offline.

Additionally, could you clarify how the online status of a camera is determined?

I’ve noticed that sometimes when a camera attempts to reconnect, its status briefly changes before reverting to offline, and I’m curious about what triggers these status changes.

  Hi Charles van der Merwe,

  Thanks for your question, I think this is an expected behavior and there might be a few things you can check. I think this is possible due to the Nx mediaserver has the mechanism that reduce the bandwidth consumption if a stream/device/camera is not recording, but only viewing on demand.

  While a camera is not in recording or not in view, mediaserver will terminate the connection and communication to the device endpoint, I think that is the possible reason the camera turns into offline. (Which is correct as the camera is not talking to anyone at all)

  In this case, you may opt to - 

  - Enable the Auto-discover and camera status check. This would allow the mediaserver to send heartbeat ack to the camera to make sure the camera is lived/online still.

  

  - You may try enable the recording but NOT record. This would force the mediaserver keep the connection alive but not keep the footage in your storage.
  

  Thanks.
