a. It is preferred to have fixed network settings instead of dynamic settings, however. To change from dynamic network
settings to fixed settings, copy the settings found through DHCP for the Local Connection and DNS, uncheck the DHCP
select box near the top of the menu, then re-enter the DHCP Local Connection and DNS settings. You can also enter your
own network settings for the recorder (these must be compatible with other devices on the LAN). If you choose to enter
your own network parameters, consider the following:
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 should be enough just to enter
the DNS1 server address.
b. You can also configure the ports the NVR. If you need to change the port numbers of your NVR, consider the following:
Web Port: This is the port that you will use to log in remotely to the NVR (e.g. using the Web Client). If the default port
80 is already taken by other applications, please change it.
Client Port: This is the port that the NVR will use to send information through (e.g. using the mobile app). If the default
port 9000 is already taken by other applications, please change it.
RTSP Port: This is the port that the NVR will be allowed to transmit real-time streaming to other device (e.g. using a
streaming Media player.).
HTTPS: HTTPS is the secure version of HTTP, the protocol over which data is sent between your browser and the website
that you are connected to. If you want to log in remotely to the NVR using Web Client, you need to complete the port
forwarding in your router. The default port number is 0443.
PPPoE: PPPoE is an advanced protocol that allows the NVR to connect to the network more directly via DSL modem.
Check the Enable PPPOE box, and then enter the User name and Password of the PPPoE.
