Video stream not working with HWN-2408MH-8P NVR

[Alfystar]

I have an NVR surveillance system with the model HWN-2408MH-8P. I managed to find the ISAPI access option from the configuration page, but I haven't found a way to access user permissions and haven't yet worked on events.

When integrating the plugin, it immediately identified my 5 cameras by entering the username, password, and URL, showing their names and some status. However, the video stream is "dead." When I try to start it, the screen is gray, and the following error appears in the system log:

Logger: root

I couldn't find any similar errors among the issues, but if I missed something, I apologize. I would love to integrate this fantastic plugin into my setup.

System Information:

• Home Assistant Core: 2024.10.4 (Docker installation)
• Frontend: 20241002.4
• hickvision_next: 1.0.19

I am available for any help and testing. Thanks in advance!

most likely you have set a codec other than H.264

[Alfystar]

Do you mean at the OS, Home Assistant, NVR or Plugin level?

[maciej-or]

at NVR video settings for each cam

[Alfystar]

Perfect, as soon as I get home I'll test it and update you!
Thanks

However I remember having glimpsed as a codec h265, so even if it is not the problem it is part of the problem.
But if I wanted to use the most advanced codec, also to save bandwidth, is there some missing package at the OS level or is it impossible?

[maciej-or]

it depends on browser, H.265 implementation is still in progress for most
https://caniuse.com/hevc
you have to wait a while

[Alfystar]

Mmm Ok, but I found same problem also in companion...

Anyway I change the codec for all camera end restart home assistant, now the error change to:

Registratore: homeassistant.components.stream.stream.camera.hwn_2108mh_8p0820210905ccrrg66709044wvu_101

Error from stream worker: No dts in 7 consecutive packets

Any other idea?

This is my current configuration:

[maciej-or]

check this issue, looks similar #209

Hi @maciej-or!
I wanted to let you know that disabling stream encryption worked!
Now by clicking on the video stream, after a few seconds you see what the camera sees.

However, the camera snapshots continue to not work and from the dashboard the camera is gray and in an "inactive" state

From the home assistant logs, however, I don't see any errors or warnings, any ideas?

Anyway we are very close to the Anyway we are very close to the solution! 😆

Current configuration:

Home assistant dashboard:

[maciej-or]

check these settings

[Alfystar]

Unfortunately my device does not allow you to choose the digest algorithm...

This is what I see:

I also try to edit video settings:

In particular enable the codec h264+

Still work on home assistant, but the preview and snapshot is dead 😭

[maciej-or]

ok, so catch the log, guide is here https://github.com/maciej-or/hikvision_next?tab=readme-ov-file#reporting-issues
and look for the urls with /picture

[Alfystar]

Hi @maciej-or , i'm here again
I log as you write in readme:
https://pastebin.com/znhZDc4g

But for what i see, no error come out, no warning, and no /picturereference inside this log...

actually reading online I also had the doubt that it is the fault of the nvr firmware since even from the hikconnect app I do not see the thrumbnails.

As soon as I have the chance I will try to update the firmware, which if I understood correctly should be in this folder for my model (HWN-2108MH-8P NVR):
Actualy version of Nvr: V4.30.300 build 210813
https://www.hikvisioneurope.com/eu/portal/?dir=portal/Technical%20Materials/20%20HiWatch%20%26%20HiLook/00%20Product%20Firmware/K20B2%28HWN-21XX%29

Is possible in your opinion?

[maciej-or]

I think you have to open dashboard with snapshot card, then request for the picture should appear in the log.
For security reasons it is always worth having the latest version of firmware.
If it is possible you must check yourself, if fw is not compatible with your device the upgrade will not start

Hi @maciej-or
I do the firmware update, but log still not contain /picture ...
This the new logs: https://pastebin.com/Cpe8XsB9
