Applies to Models: Hanwha Branded NVR (does not include WAVE servers of Work Stations)

Summary:

Hanwha NVRs can function as a DHCP (Dynamic Host Configuration Protocol) server, automatically providing IP addresses to network devices. All Hanwha NVRs have two built-in interfaces that will divide the load of the NVR. By default, the Network 1 interface will manage the Camera's network to display images on the NVR, and the Network 2 interface will manage the Viewer/ Client network. While useful in some cases, this feature can create IP conflicts if the NVR is not configured correctly. The article explains how to disable the DHCP function on Network 2 when experiencing IP conflicts.

Step By Step Guide:

1. Navigate to Setup>Network>DHCP Server on your NVR

Figure 1

2. Click Setup on the Network 2 (Viewer)

3. Click the Status Drop Down Menu and select Stop

Figure 2

4. From the Main Menu, go to Network, then Interface

Figure 3

NOTE: In Figure 3 that Network 1 (Camera) is greyed out; the network interface
does not see any connections to it. Check your cabling or connections on the other
end if this occurs.

5. Click on the Setup button for the network you intend to configure. 

6. Set the Default Gateway  to Network 2 (Figure 3)

6. Verify the IP Type is set to Static for Network 2 and DHCP for Network 1

Note: To utilize the Network 2 as a Secondary DHCP Server, its very important 
for the integrator to know how Subnetting and VLSM (Variable Length Subnet Mask)
is configured on the network. They will need to set the IP range and lease time that will
not conflict with their Primary DHCP server's IP range or subnet.
Once confirmed set the NVR's Network 2 interface to "DHCP."
