DDNS Service

DDNS, which stands for "Dynamic DNS", is a method, protocol, or
network service that provides the capability for a networked device,
such as a router or computer system (in this case, the NVR) using the
Internet Protocol Suite, to notify a domain name server to change, in
real time, the active DNS configuration of its configured hostnames,
addresses or other information stored in DNS.
A popular application of dynamic DNS is to provide a residential user's
Internet gateway that has a variable, often changing, IP address with
a well-known hostname resolvable through standard DNS queries.
This is useful if the NVR is placed on the Internet with a dynamic
public IP, which once the DDNS is properly setup, users can access the
NVR remotely with the DDNS domain name without worrying if the IP
has changed or not.
*Please make sure a valid DNS server has been configured under the
"Network Setting" page in order for this function to work properly.
*The NVR currently only works with free DDNS service provided by
"DynDNS". For more information, please go to www.dyndns.com
