Summary:

IP conflicts can arise in an NVR for multiple reasons. As an example, the network interface designated in the NVR as "Network 1" has an IP that is already assigned to a device currently on that physical network.   Other network-related issues that may not necessarily be an IP conflict, but can crash a network, is if you enable DHCP Server on Network 2 (Viewer).  This article will walk you through correcting such issues.

Step By Step Guide:

Network IP Address

1. Navigate to Setup > Network > Interface > Network on your NVR.
   
   

   NOTE: The radio button for Default Gateway should normally be set to Network 2.

2. Next to Network 2 (Viewer), click Setup.
   

   NOTE: If your IP Type is set to DHCP on Network 2 (Viewer), you are grabbing an
   address automatically from the client's network. If you plan to connect to your
   NVR remotely, you will need to statically assign an IP to Network 2 (Viewer).
   Network 1 (Camera) also needs a statically assigned IP. This sets up base IP
   range for the camera network. 
   
   Important: Never put Network 1 (Camera) and Network 2 (Viewer) into the same 
   range.
   
   In the following example, the two IP addresses are in the same range because 
   their subnet mask is the same class C 255.255.255.0 mask. If the first three 
   sets of numbers are the same with this type of mask, you are in the same IP 
   range. This will cause both networks in the NVR to crash continuously.
   
   Network 1 (Camera)
   192.168.1.100
   255.255.255.0
   
   Network 2 (Viewer)
   192.168.1.200
   255.255.255.0

3. If your Network 2 (Viewer) IP address is conflicting with anything on the client's network, change the IP address to an unused IP address.
   

   NOTE: If Network 1 (Camera) is conflicting with anything on the camera network,
   correct the IP, Subnet, or gateway accordingly. 

4. Click OK to save the changes.
   

DHCP Server

NOTE: While enabling DHCP Server on Network 2 (Viewer) is not technically an
"IP Conflict", you are handing out addresses on the client's network. This
can cause major outages on some networks. There will be very few usage cases 
where DHCP Server needs to be enabled on Network 2 (Viewer).

1. Navigate to Setup > Network > DHCP Server > Network.
   
   
2. Next to Network 2 (Viewer) click Setup.
   
   
   
3. Select Stop from the Status dropdown menu.
   
   
4. Click OK.
