Advanced TCP/IP Settings

DNS Configuration - DNS (Domain Name Service) provides the translation of host names to IP addresses on your network.

Obtain DNS server address via DHCP - Automatically use the DNS server settings provided by the DHCP server. Click the View button to see the current settings.

Use the following DNS server address - Enter the desired DNS server by specifying the following:

Domain name - Enter the domain(s) to search for the host name used by the network cameras. Multiple domains can be separated by semicolons (;). The host name is always the first part of a Fully Qualified Domain Name, for example, myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com where mycompany.com is the Domain name.

Primary and Secondary DNS servers - Enter the IP addresses of the primary, and secondary DNS servers.

Note:

This is not mandatory with regard to secondary DNS servers.

NTP Configuration - Obtain NTP server address via DHCP - Check this radio button to automatically look up and use the NTP server settings as provided by DHCP. Click the View button to see the current settings.

Use the following NTP server address - To create manual settings, check this radio button and enter the host name or IP address of the NTP server.

Host Name Configuration - The network cameras can be accessed using a host name, instead of an IP address. The host name is usually the same as the assigned DNS Name.

For more information, please see Security, on page 24.

Link-Local IPv4 Address - with UPnP™. The camera can not affect each other.

This is enabled by default and assigns the network cameras an additional IP address for use have both a Link-Local IP and a static/DHCP-supplied IP address at the same time - these will

HTTP and HTTPS - The default HTTP/HTTPS port numbers (80 and 443 respectively) can be changed to any port within the range 1024-65535. This is useful for simple security port mapping, for example.

NAT traversal (port mapping) for IPv4 - A broadband router allows devices on a private network (LAN) to share a single connection to the Internet. This is done by forwarding network traffic from the private network to the “outside”, that is, the Internet. Security on the private network (LAN) is increased since most broadband routers are pre-configured to stop attempts to access the private network (LAN) from the public network/Internet.

Use NAT traversal when your network cameras are located on an intranet (LAN) and you wish to make it available from the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router is forwarded to the camera.
