T-Mobile NVR to NVR Live View, How to?

[thesillym]

I have T-Mobile home internet at one of our properties with a Dahua nvr that I want to view live at another location using a Dahua nvr. T-Mobile has a double nat network that does not allow port forwarding, static ip, or ddns.

We have tried setting up a Raspberry Pi running a zero trust tunnel on cloudflare, but can’t figure out the correct settings or if it is even possible.

We have also tried using a Raspberry Pi running Nord VPN with static ip. Can’t get that set up correctly either.

The P2P function will work when viewing with the DMSS app, but I do not know how to use the P2P with another nvr.

Has anyone been successful in a similar setup?

If this has already been discussed here already, can someone please provide a link? Or link to a YouTube video?

Any help is appreciated. Thanks

modern Dahua NVR (4xxx-EI / 5xxx-EI) have possibility to connect to cameras over P2P.
on camera list, you click on manual add button, change camera type (company) to Register and then ip address input is replaces with serial number one..

I never tried this function to connect other NVR - but you can test it...

I have an older nvr NVR4K16P with 3.210.0005.0 2016 firmware. I don’t think I have that capability. Maybe it is possible to translate the p2p info into ip/port?

Only the second NVR (where you want connect remotely) need to be modern one

I would prefer to find a solution without buying a newer nvr, but will buy a new one if needed.

any p2p vpn solution, which will works for both ways hidden after CGNAT...

like zerotier...

Can someone provide instructions to setup Zerotier or similar? Or link to a youtube video or something? I've got the basic setup, but the instructions that I have found do not explain how to view the live video stream from a remote location.

There are teens of videos on Youtube about zero tier network configuration.
But they require IP network/routing basics and knowledge how VPN works..

You need to connect two local networks hidden behind routers so that their resources (especially NVRs, which works here as servers) are mutually visible to the other network. Of course, both networks must use different private IP address classes.

You should find local IT network guy, who will configure peer-to-peer VPN solution for you onsite.
