I just purchased my 3rd Dahua NVR from Empire Tech on Amazon for use at work.
Model
NVR16CH-AI-S2,
hardware vers V1.0.
system vers V5.000.0000000.1.R
Manufacture date 06/24/2025

I have 2 others, 16 channel, that're a couple of years old running on the same network. They both work great on P2P while on the same LAN, a Verizon cell, and Smart PSS Lite from local and remote locations.
This new NVR only works while my cell is connected to the same LAN. The P2P in web setup on the NVR shows online.
I've turned on/off P2P a few times, Tried DHCP and gave it a static address with the DNS of 8.8.8.8 / 8.8.4.4. Still only works with my cell on the LAN.
I did notice one thing though, on the DMSS app while on the LAN the cameras work live but the "get info" shows "failed to get". The other 2 show "On Line". The Smart PSS desktop app does not see the NVR at home or at work.

The new on has a menu that looks like Amcrest. I did not sign up for the Dahua account on this or the other 2 that are working fine.

I brought it home and tried on my LAN with spectrum and a ASUS / Tomato router and i get the same issue.

Has anyone dealt with this issue?
 
I have the same NVR except with the built in ports/switch, just purchased over the holidays and still messing with it.

It has bugs, assume you have this new "NEXT" interface?

Yes, it's the same. It's starting to look like the reason it's not working is because I didn't get the dahua DMSS account and there's a very good reason for that. We have 2 company locations with 3 NVRs in them. Multiple employees have DMMS on their cell phones for them, including 3 different owners, 2 of them have Dahua NVRs at their home and camps, so as of now 6 NVRs total. So if I get a DMSS account for this one which is going to an owners home, what about the other NVRs that are already on his DMSS phone app? They don't use a DMSS account, will they need to be added to the DMSS account? If I setup everyone's DMSS with one overall account then they would be able see each other's NVR. I am hesitant to try various scenarios because Dahua locks the serial # of the NVR to the DMSS account. People have been complaining that they cannot remove the NVR after it's been added to a DMSS account.

I might have to delete all of the DMSS apps and then get each owner to setup a DMSS account. From there they could, or might be able to share the NVRs between those that they want to share with.

So far I'm not sure if the lack of a DMSS account is what's stopping the connection.
 
I actually hadn't tested P2P remote off my LAN ........and Yes, I'm seeing the same exact things you are.

Standby, I have a Dahua acct on DMSS on my phone, but dont typically login to it.
I'll test and report back
 
Nope that didnt change anything.

Works fine on LAN but P2P, while it shows Online, does not work via DMSS remote and SmartPSS does not see it local.
P2P does not work outside of the LAN

Combined with at least 2-3 other non-functioning features, I'm returning mine.
