Dahuas new ITC cameras are really good. ITC215 and ITC231

It would be great if the ANPR from these would be a part of the analytics integration in Nx.

So that the license plates would be searchable in Nx + block- and pass-lists to trigger events.

    Fredrik,

    We are actively working on deep AI integration with Dahua cameras and Dahua team seems to be supportive.
    I'll check if we have a camera with ANPR. In case if we do not, we'll try to get one and do it.
    Thanks.

    One issue though. We won't support block and pass lists for now. The support will be introduced with events/actions redesign which is 2 versions away.

    I agree with Fredrik on this. That's a feature we use on other VMS's. Would be great to get NX to do it too.

    Any news on ANPR integration, like the one you got with HIK?

    Would be really good to be able to create bookmarks with the license plate, and trigger events based on passlist/blocklist.

    This would be an very useful option.

    We also have customers who could like this option.
    Meanwhile we have to offer other solutions. But they are not so useful as Nx Witness.

    Looking forward to see comming releses with Nx:)

    Gentlemen,

    We encountered some hurdles to take which are outside our control. We hope to be able to support Dahua LPR in a 4.1 patch. 

    There is also some good news to mention. The number is supported analytics will be  increased a lot in 4.1.

    Hi Kai Magnus Nymann,

    Unfortunately, Santa's elves didn't provide the proper information to enable us to do the LPR integration at this stage, therefore it is postponed till an unknown date. I have asked some clarification from our dev team and will let you know when I know more.

    Hi Fredrik Ahlsen

    Our team is right now working on this feature. Very likely it will be available in some of the upcoming patches.

    That is good news.

    Are you testing with both their AI ANPR cameras like IPC-HFW7842H-ZVH, and the ITC cameras like ITC215-PW6M-IRLZF-B?

    I can provide remote access to a ITC camera if needed.

    Sorry, my previous answer was misleading. ANPR support for Dahua cameras is already completed and tested. It will be available in 4.2 September patch.

    We've tested it with IPC-HFW7442H-ZFR camera and do not expect any issues with the cameras you've mentioned.

    You can test it by installing 4.2 September patch. If you don't have access to our patches, just tell me, I'll post it here as soon as it is released.

    Hi Kai Magnus Nymann,

    Have you tested it? The ANPR support is made through the Dahua API, and should apply to multiple models. Which models should be confirmed by Dahua.

    When I searched for the Dahua ITC215-PW4I-IRLZF27135, I did notice that Dahua marks it as Project only, this might indicate they use another API for the ANPR function. If that is the case, I would encourage Dahua to unify the base API in the firmware of this project only device.

    The camera use the same API.
    But on auto by default it is detected by Nx with Vendor:General instead of Vendor:Dahua so the Dahua plugin will not be enabled in Nx.

    So it needs the same workaround as the rest of the ITC cameras.

    Kai: I suggest that you set up direct access to the camera on port 80 and 554 then give access to Norman through a private support ticket.

    Fredrik Ahlsen Thanks for adding this note. That is also an option of course.

    Kai Magnus Nymann, at this stage, remote access isn't necessary. If you can share a screenshot from with the Nx Witness Desktop client of the Camera Settings menu, tab General, that reveals Vendor, Model, and Firmware, I should be able to create a fix.

    For Windows: C:\Program Files\Network Optix\Nx Witness\MediaServer
    For Linux: /opt/networkoptix/mediaserver/bin/

    3 - Now start the mediaserver application again
    4 - Add the device again

    To stop and start the media server, please do it as follows:

    For Windows:

    Hi Norman.

    It shows vendor Dahua after this update.

    But I have not succeed to read plate nr in nx yet.
    And is only shows object type: Face, Person, Unkown and Vehicle.



    May be is something with the ITC camera. I will take an closer look on camera settings tomorrow.

    You need to add a analytics rule to the camera and select "Traffic detection" on the list of events.
    Choose "Show notification"

    After that you should start to see vehicle and license plate objects.

    Hi.

    Traffic detection does not appear in event list.

    Have tried factory default on camera, deleted and new add in Nx etc.
    ITC215 read plate nr.
    But Event list only shows: alarm and system events.

    Hi Kai Magnus Nymann,

    If Traffic Detection doesn't appear, it is most likely a firmware issue.
    Nx, displays and uses the events, the camera provides.

    You can check this list with the help of Wireshark.To capture the list you can take the following steps:

    1. Remove the device from the system.
    2. Start Wireshark on the Nx mediaserver with the camera IP address as the host filter
    3. Add the device to the system and wait till an image is shown.
    4. Stop and save Wireshark
    5. Check or share the Wireshark trace file to see which events are supported.
