Dahua NVR5216 hard reset?

The FW version must be an older version as it looks MS XPish with the graphics. See the attached photos
You have version 3 firmware. The latest is version 4. I'm running a fairly old 5216-4ks2 with version 4 firmware and as of a couple months ago it worked with P2P, although the smartPSS and DMSS apps had to be upgraded with newer versions. Be careful if upgrading the firmware. There are V1 and V2 hardware versions of the 5216-4ks2, and the V1 hardware cannot use the newer V4 firmware. Ironically, the V3 firmware firmware won't tell you which hardware version NVR you have (the V4 firmware does tell). I believe you can find out from the part number sticker on the NVR case. My V1 NVR say its part number is 1.0.01.23.10840. I vaguely remember the V2 stickers say something to that effect, but don't remember the details.

This NVR part number is 1.0.01.23.10842
 
Comparing this NVR to the open box Dahua NVR I purchased - this one does not have a reset button, but the open box NVR does. This NVR says "NVR" on the front panel while the open box Dahua NVR says "Dahua". I'm getting the feeling that the "NVR" branded NVR is an OEM Dahua, which can be an older model. Both are NVR5216-16P-4KS2, but the open box model Dahua is a NVR5216-16P-4KS2E.

I wonder if this NVR is even 4K capable

Ok, so you still use a V1 with Version 3 FW?

My V1 5216-4ks2 originally ran V3 firmware. A few years ago I upgraded to a fairly early version of the V4 firmware. I do not use the very latest V4 firmware that I could be using.

Detail you probably don't care about:
Somewhere during the V4 firmware evolution, dahua added code to prevent the NVR from working with chinese market cameras. The firmware version I use is the newest one that doesn't reject the chinese market cameras.
 
mine is a 4K2SE

V4.002.0000000.7.R, Build Date: 2024-07-17

Thats the FW that was required to upgrade to last year when the made all the changes to their P2P service. Anything older is iffy on whether it will communicate with the legacy P2P servers?

Come to find much of the problem wasnt so much the NVRs as it was SmartPSS and how it communicated with the P2P servers. Thats why/when they dropped support for SmartPSS and forced SmartPSS Lite
 
So, I guess my question now is, can I use this generic Dahua nvr with newer cameras and use SmartPSS lite and DMSS to view events on my Android phone from afar?
 
Easy thing to test.

Load up DMSS on your phone (I dont know Android OS so I cant help there), turn on P2P on the NVR, add the NVR via Serial number to DMSS, and turn off your wifi on the phone to simulate being remote.
 
You certainly can if you set up a VPN or use tailscale.

If you want to do P2P it might be sketchy or not work.

Only way to know is to give it a try. Just enable P2P and following the steps and see if it let's you see it off wifi.

I've been using P2p for what about 6-8 months now with no issues. Longer on some remote NVRs.

I only use VPN now if we're going to be gone for an extended period, mostly just as a backup method of access when remote.

Again watching the firewall its not doing anything funky.

You should be able to test in in 15 minutes

Depends on how anal one is.
I run all of my cameras at high bitrate and high FPS an its not a problem to me.

try and and find out

Ok, here's the NVR camera settings for 4K-X. The most the NVR supports is 8192

Also notice that I cannot check the audio/video selection under the main stream. I wonder if that is due to not having a hard drive installed?

And I can't seem to manually update the time. It shows update failed every time. I know there's a connection via ethernet as it shows it is working. Maybe the wrong port for the update?

I know. The current setup is very temporary. In fact, it sits on top of my laptop when in operation. Have to spend a few minutes moving the setup from on top of my laptop
 
Ok, fixed the time issue, had the wrong gateway. Unfortunately, I can't access the webpage because it wants to download the plug-in on Palemoon or the chrome plugin on IE and Chrome. When I try to install the web plugin on Palemoon, my ESET anti-virus has a fit and won't let it install it. I was able to install it for the camera GUIs, but it has an issue with the GUI for the NVR

Exclude it from ESET.
