Adding a DCS-8526LH camera to Nx Server
Answered
Hi guys
I'm having some problem streaming this particular camera to my Nx Server.
It support ONVIF Profile S, and I have no trouble adding it to my Nx Server. However, streaming doesn't work. I do manage to get it running on my ONVIF device manager though. So I'm wondering what could be wrong.
Regards
Kevin

Hi Kevin,
Please refer to the article here when you want to submit the support request next time. It will make the whole troubleshooting process much more efficient. Regarding this case, could you check and provide more detailed info for us?
You may check with the following items,
1. Confirm Nx software version is up to date.
2. Check the firmware version of the camera is the latest one
3. Provide the vendor and model info of the camera
4. The result when you press the Diagnostics button on the stream windowThank you.

Hi Wendy
I more or less run through the standard procedures. Guess it's my fault for not stating that in the first place. Firmwares are all running the latest, and adding of camera is successful. Camera model is stated in the subject title, brand is D-Link. This is a local connection, so I assume no network diagram is needed. The problem is kinda self-explained without the need for recorded video. Let me know if that's required. I didn't not know there's a Diagnostics button though lol. Here's what it says.
###
Confirming server availability.
OKConfirming camera is accessible.
OKConfirming target camera provides media stream.
FAILED: Too many media errors. Please open camera issues dialog for more details.Diagnostics complete
###There's nothing in the Camera issues dialog.

Hi Kevin,
Thanks for your information. Please check the following items for me,
1. Please upgrade your Nx service to the latest 4.1 patch and retry.
2. Confirm the camera provides the stream to Nx only. If there's ant VMS or streaming client query the stream from the camera, turn it off first. Some cameras might not be able to handle too many RTSP connections at the same time.
3. Collect the Wireshark packet on the server machine (Start capturing -> Close the stream window -> open the stream -> Wait for a while -> Stop capturing). You may refer to the document here for more instruction.
4. Enable camera recording and leave it for a while. Check if you could see the archive there. Sometimes the device just needs more time to initialize the RTSP session.
Thank you.

Hi
Sadly it's not working yet.
1. Upgraded version all this while.
2. This is a POC, so no other connections exist.
3. I'm not sure how to capture this as I'm using an Ubuntu for server.
4. There's nothing in the recording.Regards

Hi Kevin Chen,
- Please confirm which version + build you are using.
- You could try to set the camera to Keep camera stream and profile settings, this can be done in the Camera Settings menu, tab Expert.
- I assume you use Ubuntu as a headless server? If that is the case, you can't use Wireshark, but you can run TCPdump in the terminal. Enter the following command:
tcpdump host <camera-ip> -i en0 -W 10 -C 300 -w <desired-filename>
For example:
tcpdump host 192.168.178.40 -i en0 -W 10 -C 300 -w cameracapture
This will create up to 10 files of 300 MB each for a specific camera with the designated IP address. In order to capture the moment, it is recommended to set up a rule to get notified when the issue occurs.
In this way you can find where it goes wrong in the communication between camera ⇽⇾ server.
You also can forward the camera, so we can add it to our test environment for further investigations.

Hi guys

Hi Kevin Chen,
According to the Wireshark file I can see the camera is added (HTTP 200 OK), but as soon as it builds the RTSP streams it fails indeed and the following replies can be seen:
- RTSP/1.0 404 Stream Not Found
- RTSP/1.0 454 Session Not Found
Can you forward the camera via port forwarding, so we can add it to our test environment? You can email the public IP address, forwarded ports and credentials to <email-removed>.
Please also answer question 1 and 2 from my previous reply;
- Please confirm which version + build you are using.
- You could try to set the camera to Keep camera stream and profile settings, this can be done in the Camera Settings menu, tab Expert.

Hi Kevin Chen,
Thank you for forwarding the camera. We did the investigation and unfortunately we couldn't fix it ourselves. So I created a task for our development team for further investigation.
Please keep the device available until further notice. I'll update you as soon as I know more.
