NVR3216 Network Setup

We've had this NVR in a business environment with 4 IP cams. A power event has caused the network screens to revert to default and I'm trying to rebuild so I can get it back online.

I know what all the IPv4 fields should be populated with but it is forcing me to populate IPv6 as well ("IPv6's Host IP Gateway DNS can not empty (sic)").

IPv6 is not even employed on our network. Is there a way to disable it on the NVR? Or can I get some help with some IPv6 default figures? I've been though it with IT guy who knows IPv6 format but this NVR predated his work so only so much help there.
 
More info needed, please:
  • What is the EXACT model # of the (Dahua?) NVR?
  • Are the cams not connected directly to the NVR but instead to a POE switch?
If you know what the router's LAN subnet is and the range of its DHCP pool, consider disconnecting the NVR from the LAN and setting in a unique, static IP (IPv4) for its LAN that is in the same subnet as the router's LAN but OUTSIDE of the router's DHCP pool; use subnet mask of 255.255.255.0, gateway IP (router's LAN IP) and Primary DNS (same as gateway IP), save it then re-connect to LAN.

    • It's most likely a generic. The front case just says "NVR / Network Video Recorder" and the label underneath has Model: NVR3216, Channel: 16CH and a serial number.
  • Are the cams not connected directly to the NVR but instead to a POE switch?
    • That's correct, the cameras are scattered about the network and plugged into PoE switches.

I've got the IPv4 fields correct for my router. The bigger thing is the IPv6 screen 1) not being needed on my network, 2) but don't know what default values to force into it since it won't save config without IPv6 populated.

If I can't get this old NVR going, is a $99 Ubiquiti from B&H going to find older IP cameras?

If you're referring to a router, you should not even need one if you assign unique static IP's to all the cam's and the NVR's LAN, all in the same subnet.

If it insists on IPv6 at that point, with no router connected, I'd say your NVR got hosed by that "power event".

Sorry, I was referring to the cheapest NVR that B&H had listed. I only have 4 cams & 2TB so don't need much.

I'm beginning to think it's hosed too.

I would agree...and $99 sounds about right for a 4 channel non-POE since you can move the 2TB over to the new one.
Just insure that NVR can handle the bandwidth of your cams since we haven't covered your cam's # of MP, resolution, frame rate, bit rate, etc.
 
So I'm thinking the NVR is hosed too and even if not, I can't solve it. Since it has some years on it and I could barely manage it (no manual or installer support, etc), I want to replace it. And I don't really want to bottom-dollar a new NVR and maybe miss out on a feature. I would like to keep my old cams; they're 4 IPC-HFW2100N which googles to Dahua-made although they're not marked Dahua. So they're 1.3mp, but I don't know frame rate & bit rate. Plus I have an eyeball style cam that I can't pin down model, specs. And I could use 2 more bullets like the Dahuas but current. So lets say an NVR that would handle a minimum of 8x 1.3mp IP Cams, would come with storage already installed, and have 30 days of lookback footage. Would, for instance, a 4216 (ebay, $171) plus buying storage separately do the trick?
