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.
DNS servers - en
ter 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

Use the following NTP server address - to
create manual settings, check this radio button

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 35.
Link-Local IPv4 Address - This is enabled by default and assigns the network cameras an
additional IP address for use with UPnP
™. The camera can have both a Link-Local IP and a
static/DHCP-supplied IP address at the same time - these will not affect each other.
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.
