2 Quick Configuration
2.1 Software Setting
IPC needs to configure IP address which should be the same as the IP address of NVR during use.
2.1.1 Network Setting
Step 1 Enter “Main Menu”> “System Setting”> “Network Setting”interface, as shown in Figure
2-1.
Figure 2-1
Step 2
Set corresponding IP address to the '' IPAddress'', ''Subnet Mask'' and ''Default gateway'', click ''Save''.
2.1.2 IPC Configuration
The IP address of IPC and the IP address of ''Network Setting'' should be kept in the same network
segment.

Step 1
Enter “MainMenu”> “RemoteDevice”or “MainMenu”> “IPC”configurationinterface,asshown
in Figure 2-2:
Figure 2-2
Step 2
Click ''Device Search'' and corresponding IPC can be searched. Attention: It will fail to search
corresponding IPC if the IP address of IPC and the IP address of NVR are not in the same network
segment.
Step 3
Click the icon under ''Edit'', enter ''Modify IP'' configuration interface, as shown in Figure 2-3:

Figure 2-3
Step 4
Click ''Confirm'' after configuring corresponding IP address, the IP address of IPC is successfully
saved. Attention: NVR products from some manufacturers may not support modifying device IP
online if the “ ”in front of “Onvif”displays gray. It needs to login the WEB interface of IPC to
modify IP address via PC under this circumstance, refer to IPC operation manual for more details.
Step 5
Click ''Add'' to add corresponding IPC into the NVR device channel, check if it is well connected via
the icon color of ''Connection Status''. It means successful connection for the system when the color
of the circle turns from red to green.
Note:
Differences may exist to the configuration interface for different NVR devices.
It will fail to search corresponding IPC if the IP address of IPC and the IP address of NVR are not in
the same network segment.
