4.11.1 Basic Setup

The network adapter interface is shown as in Figure 4-86

IP Version: There are two options: IPv4 and IPv6. Right now, the system supports these two IP
address formats to access it.

MAC address: The NVR has a unique MAC address. It is for you to access in the LAN. It is read-only.

IP address: Here you can use the up/down button () or input the desired IP address. Then
you can set the corresponding subnet mask the default gateway.

Default gateway: Here you can input the default gateway. Please note the system needs to check
the validity of all IPv6 addresses. The IP address and the default gateway should be in the same
IP section. That is to say, the specified length of the subnet prefix should have the same string.

DHCP: This will automatically obtain your network information. When the DHCP function is
enabled, you can not modify the IP/Subnet mask /Gateway. These values are from the DHCP
function. If you have not enabled the DHCP function, IP/Subnet mask/Gateway display as zero.
You need to disable the DHCP function to view the current IP information. When PPPoE is used,
you can not modify IP/Subnet mask/Gateway.

MTU: This is to set MTU value of the network adapter. The value ranges from 1280 -7200 bytes.
The default setup is 1500 bytes. Please note MTU modification may result in network adapter
reboot and network disconnection. That is to say, MTU modification can affect your current
network service. The system may pop up a dialog box for you to confirm the setting when you
want to change MTU setup. Click the OK button to confirm and reboot, or you can click the
Cancel button to terminate the current modification. Before the modification, you can check the
MTU of the gateway; the MTU of the NVR should be the same or lower than the MTU of the
gateway. In this way, you can reduce packets and enhance network transmission efficiency.
