Compatibility issues with my Dahua NVR (DHI-NVR5216-16P-I Firmware V4.001.0000000.0, Build Date: 2020-06-17) and attached Cameras

[Longview]

I am having compatibility issues with my Dahua NVR (DHI-NVR5216-16P-I Firmware V4.001.0000000.0, Build Date: 2020-06-17) and Cameras (SD49425XB-HNR 25x, LPC-B52IR-Z12E-S2, SD1A404XB, PTZ5A4K-25X)​

The NVR stopped allowing local login to the cameras via the IE Icon, I tried a few other browsers with no luck, now the PTZ Cameras won’t respond to the NVR request for PTZ adjustment, but a laptop connected with Smart PSS Lite with direct them without flaw.​

Had a technician look at it and he suggested I update the NVR Firmware that the NVR claims is the latest ?), so should contact contact Dahua to receive it or is this NVR End Of Life?​

The NVR is obviously older; do I need a newer model NVR with updated software or just firmware update for my existing NVR to manage my cameras.

So the NVR just woke up one day and decided not to allow access to the cameras?
What else happened? I'm guessing a network related change...

Can you see the cameras LIVE when logged into the NVR on the LIVE tab? (Not the IE button)

Can you log into the NVR via its Web GUI? Typically by default at 192.168.1.108

Login to the NVR, go to Security and turn Private protocol Authentication mode to 'Compatible mode'.
Test if the cameras connect.


The latest update to this NVR (pictured) is V4.002.0000000.4.R, Build Date: 2024-07-25 .
This takes away all of the 2020 firmware 'covid' thermal camera detection stuff.

Use Dahua support website version tool update. support
If this doesn't work, send me a PM and I'll send you a copy of the firmware.

Can you see the cameras LIVE when logged into the NVR on the LIVE tab? (Not the IE button), Yes I can see them Live.
Can you log into the NVR via its Web GUI? Yes Login is successful but my NVR address is different.

Tried my serial number and it did not accept? Could you send me a link to the firmware at your convenience.

I have the software but told it may not work unless it is an OEM Device which it is. I went to download from the Dahua site and it can not validate the Serial Number?

Got it from Andy three years ago, I guess I will try the Firmware and see if it works or not?
