[Camera Support]: Unable to get RTSP stream into Frigate from Annke C500P cameras

[holkehan]

Describe the problem you are having

I have working Annke C500 (and Annke AC500) and ordered 2 Annke C500P cameras. Now I can't get the stream working. I have triple checked the camera configurations and they are fine. I'm able to open the stream on the C500P cameras with VLC. But Frigate errors out.

So I have this minimal configuration file for testing. By changing the IP to .150 I get the working camera feed from the C500, but the new C500P at .153 fails

Both are set to same streaming setting (H264, etc)
They are in isolated network
The credentials in the URL/the URL are correct, the stream works with VLC
Also have tried with go2rtc, without luck

Any tips?

The error message "Operation not permitted" when opening the RTSP stream from your Annke C500P suggests a network or authentication issue, even though VLC can connect successfully.(1)

For Annke cameras (which are Dahua OEM), the recommended RTSP path format is:(1)

cameras:
  dummy_camera:
    enabled: true
    ffmpeg:
      inputs:
        - path: rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0
          roles:
            - detect

(1)

The path you're using (/Streaming/Channels/101) is the Hikvision format, not the Dahua/Amcrest format.(1) Annke cameras typically follow the Dahua RTSP URL structure.(1)

Try these RTSP paths for your Annke C500P:(1)

• Main stream: rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0(1)
• Sub stream: rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=1(1)

If you need to use go2rtc for better compatibility, configure it like this:(2)

go2rtc:
  streams:
    dummy_camera:
      - rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0
      - "ffmpeg:dummy_camera#audio=opus"

cameras:
  dummy_camera:
    enabled: true
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/dummy_camera
          input_args: preset-rtsp-restream
          roles:
            - detect

See the FAQ in the official docs about why a stream might work with VLC but not with Frigate or go2rtc: https://docs.frigate.video/troubleshooting/faqs/#my-rtsp-stream-works-fine-in-vlc-but-it-does-not-work-when-i-put-the-same-url-in-my-frigate-config-is-this-a-bug

[NickM-27]

Yes, Frigate has a default timeout much lower than that

[holkehan]

Could you @NickM-27 point a direction where I can adjust the timeout time? I have tried a lot of thing but none with success..

[NickM-27]

You can adjust the steam timeout but odds are you'll still not get frames in time for the main checks and they'll restart the stream.

[holkehan]

I see. Any recommendations, what could I still try to get these cameras working with Frigate? Or do I just have to replace the cameras?

[NickM-27]

My recommendation would be to replace. You could look at using the latest go2rtc version which supports preloading
