5.5.1 General

5.5.1.1 General
If you connect to a router allows to use DHCP, please check the DHCP box. The router will
assign automatically all the network parameters for your NVR. Unless the network is
manually addressed below parameters:
IP Address: The IP address identifies the NVR in the network. It consists of four groups of
numbers between 0 to 255, separated by periods. For example, "192.168.001.100".
Subnet Mask: Subnet mask is a network parameter which defines a range of IP addresses
that can be used in a network. If IP address is like a street where you live then subnet mask
is like a neighborhood. The subnet address also consists of four groups of numbers,
separated by periods. For example, "255.255.000.000".
Gateway: This address allows the NVR to access the Internet. The format of the Gateway
address is the same as the IP Address. For example, "192.168.001.001".
DNS1/DNS2: DNS1 is the primary DNS server and DNS2 is a backup DNS server. Usually, it
should be enough just to enter the DNS1 server address.
