Summary:
IP conflicts can arise in an NVR for multiple reasons, on the network designated in the NVR as "Network 1" this can happen if "Network 1" has an IP that is the same IP as one of the devices on "Network 1." 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 (Figure 1)
NOTE: The radio button for Gateway should normally be set to Network 2 (Figure 1)
Figure 1
2. Click Setup on the Network 2 (Viewer): (Figure 2)
NOTE: If your IP Type is set to DHCP on Network 2(Viewer), you are grabbing an
address automatically from the clients 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, never put Network 1(Camera), and Network 2(Viewer)
into the same range
Example:
Network 1(Camera)
192.168.1.100
255.255.255.0
Network 2(Viewer)
192.168.1.200
255.255.255.0
These two IP adresses 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
3. If your Network 2(Viewer) IP address is conflicting with anything else on the client's network please change the IP address to an unused IP address (Figure 2)
NOTE: If Network 1(Camera) is conflicting with anything on the camera network,
correct the IP, Subnet, or gateway accordingly, both screens are identical
to Figure 2
4. Click OK to save the changes (Figure 2)

Step By Step Guide DHCP Server:
NOTE: While enabling DHCP Server on Network 2(Viewer) is not technically an
"IP Conflict", you are handing out addresses on the clients 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 (Figure 1)
2. Click Setup for Network 2(Viewer): (Figure 1)
Figure 1
3. Change the status to Stop (Figure 2)
4. Click OK (Figure 2)
