Dahua Cctv

[Markee72]

Hi, 

So really need some help please.   The system is a Dahua NVR with 3 cameras installed, and for the last 4 years on sky broadband and it all worked properly. The NVR is hardwired via ethernet directly to the router.

Since changing to EE home broadband, their is no remote access  available to the DMSS app on mobile devices and the NVR says it is "offline".  

I can only view the cameras on the connected TV ( hdmi cable)

EE said they havent any" blocks" in place, however the NVR has pulled through the correct gateway and IP addresses and DHCP is enabled.

The manufacturer, have said there is nothing else they can do and it's a problem with the Broadband provider.

Does anyone have any suggestions/ solution please.

Thanks

@Markee72 As the EE router does not have or support a DDNS setting, then you are never going to see the NVR system remotely over the internet when you are away from home, it is just the nature of how these old systems worked. When it was setup originally, did you do it or was it someone from the installer company set it up for you. Have copied a link from a previous OP post that you can read below. The only method now is to have a device on 24hrs per day, and run some DDNS simulation software that allows you to see the NVR, or speak to the CCTV company to see if they have a more up to date recorder that you can replace your existing one with that does not rely on a DDNS connection. 

What EE router do you have?

Follow @Mustrum as suggested below, looking at the manual no DDNS required.

How can that be so? Altho' I'm still on legacy BB I can see my Ring Doorbell & my IP Camera from afar w/out employing any DDNS? How is that any diff from OP's situation?

@Markee72    It would be worth starting the setup of the DVR again now it is connected to the EE router. Altho ugh you say some settings have been pulled through, the Sky Router settings are different to the EE ones.

I can't see that it needs DDNS or that any ports need to be open, there are plenty of systems that do not need those features.

Give the setup another go, and let us know if you do not get the positive message as per the manual.

Hi Markee,

I am a professional Dahua Installer, who works in the comms industry. 

In instances where the customers' leased lines haven't been activated yet, we normally put in mobile broadband connections.

Unfortunately, on the few occasions where the customer has provided their own (EE), the NVR has ALWAYS shown offline and won't connect to smartPSS or DMSS. So there is definitely something within the EE network that is preventing access to the NVR.

I haven't looked into into it much with EE beyond that if I'm honest, as these are usually only temp connections for us, so not worth the effort. But I did have a similar issue with Vodafone and remote access to networks. It's all to do with the way that the provider 'tunnels' the traffic. It's not standard, generally with shared public ips.

The best advice I can give is to try using the DDNS option, and setting up a free ddns account at somewhere like dynu dns, however, if it's a similar issue to Vodafone, I cant see this option working but worth a try. 

Also, ensure all the ports are forwarded and open for your NVR, you can get the port settings from the NVR directly, either by looking on the NVR via a monitor or logging into the NVR using its IP whilst on the network. Have you tried setting the NVR as DMZ host in the router by any chance?

@Craigr2110 Would have thought that you knew all the little tricks to get this going?

[Craigr2110]

So do a lot of customers Jim haha

I've tried all sorts. Where it gets even more confusing is that if he has an EE phone, chances are that it connects on the DMSS app no problem! So what's the difference? Try telling a customer its EE's network, when they show you it working on their mobile phone!

The fact is, we can only control what happens our side of the router. The 'private side.' Anything on the public side, from the router back to the network, is EE's domain. We can't change anything on this. Other than tweaks to ports and settings in the router.

The only other things I can think of, if the things in my last post didn't help, is to ask EE for a static IP, then all traffic SHOULD be directed at your sole public IP, rather than tunnels, or, if it is in fact the router, then you could try disabling DHCP, or put it in to 'modem mode', and then connect it to an old router via its WAN port, and let that router handle all the traffic.

On a computer or mobile device, you can install tailscale, which effectively creates your own 'local' network in the cloud, so everything is accessible, but this isn't an option to install on the NVR

I mainly posted so that Markee didn't think it was settings his side, because other than router settings, there is nothing else he can do.

@Craigr2110 Pretty sure he got that from the comment that he posted! "The manufacturer, have said there is nothing else they can do and it's a problem with the Broadband provider."

You never know until he replies, might be up and running a ok now!

[Craigr2110]

He also said that EE said it wasn't them....

But noted..... ill leave all future comments to the Ace Contributers.

@Craigr2110 That;s not what getting at, you are in the unique position of installing systems such as you mentioned, there is always something that possibly goes amiss, and a lot of it is time and money, restrictions etc, you surely just don't do if EE or vodafone etc to awkward do not touch these with a barge pole, any router can be changed and difficulties can happen at any time! Any company will say nothing wrong our end, so easy to do, and a lot of end user's buy and think, were good for life so just does not work that way. It's the way of the forum, either good result/bad result, just sometimes no way of knowing. There is no intention to disparage in anyway shape or format. If you feel so then i truly apologise.
