Question:

How do I configure the network settings on an NVR with two LAN ports?


Answer:

It depends on how your cameras will be connected.


If your cameras are connected to a switch on the network (cameras > switch > router/modem OR cameras & NVR > switch > router/modem):

  1. In the NVRs network settings, you can set the 'working mode' to 'Net Fault Tolerance'
  2. Set 'Default Route'/'Main NIC' to the LAN port connecting the NVR to the internet
  3. You can either enable DHCP, or set a static IP for the NVR
    1. If you set a static IP for the NVR, you need to put in a gateway manually. DHCP will auto fill in the IP Address and gateway for the NVR.


  1. An example of a Net Fault Tolerance setup: The cameras and LAN 1 on the NVR are connected to a switch which is then connected to the router (cameras & LAN 1 on NVR > router).
    1. Set 'Default route'/'Main NIC' to LAN 1
    2. LAN 1 IP Address: 192.168.1.64; gateway: 192.168.1.1 (you can set a static IP or do DHCP)
    3. When adding cameras, set their IP addresses to 192.168.1.x (x being any number, just make sure the IP address you set for a camera is not being used by anything else on the network).


If your cameras are connected to a switch that is connected to one of the LAN ports on the NVR (cameras > switch > LAN 1/2):

  1. In the NVRs network settings, you can set the 'working mode' to 'Multi Address'
  2. Set 'Default Route' to the LAN port connecting the NVR to the internet
  3. Set an IP address and gateway for LAN 1 and LAN 2. You do not want the IP address or gateway of both LANs to be the same, you will get a IP conflict error.
    1. Toggle between the LAN 1 and LAN 2 settings by clicking on the 'Select NIC' option
    2. You can enable DHCP for both, but the LAN port that has no internet will get a 169.x.x.x address
      1. If you want to set a specific IP for either LAN ports, you may do so. Change the 'Select NIC' option to desired LAN port and disable DHCP, then type in desired IP and gateway.
        1. The gateway of the LAN port that is connecting the NVR to the internet needs to be the same as other devices on the same network.
        2. The gateway of the LAN port not connected to internet can be set to match the subnet of the IP of that port. Ex: IP: 192.168.1.64, gateway: 192.168.1.1


  1. An example of a Multi address setup: You have cameras connected to a switch which is then connected to the NVRs LAN 2 port (cameras > switch > LAN 2) and LAN 1 is connecting the NVR to the internet (LAN 1 > router).
    1. LAN 1 IP Address: 192.168.1.64; gateway: 192.168.1.1  (you can set a static IP or do DHCP)
    2. LAN 2: 10.1.10.220; gateway: 10.1.10.1
    3. Default Route: LAN 1
    4. When adding cameras, their IP addresses need to be 10.1.10.x (x being any number, make sure the IP address you set for a cameras aren't conflicting with any other camera).
