Dahua DDNS and Client-end Introduction
1) Background Introduction
Device IP is not fixed if you use ADSL to login the network. The DDNS function allows you to access the
NVR via the registered domain name. Besides the general DDNS, the Dahua DDNS works with the
device from the manufacturer so that it can add the extension function.
2) Function Introduction
The Dahua DDNS client has the same function as other DDNS client end. It realizes the bonding of the
domain name and the IP address. Right now, current DDNS server is for our own devices only. You need
to refresh the bonding relationship of the domain and the IP regularly. There is no user name, password
or the ID registration on the server. At the same time, each device has a default domain name (Generated
by MAC address) for your option. You can also use customized valid domain name (has not registered.).
3) Operation

and domain name.
