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
Before you use Dahua DDNS, you need to enable this service and set proper server address, port value
and domain name.
 Server address：www.dahuaddns.com
 Port number：80
 Domain name：There are two modes: Default domain name and customized domain name.
Except default domain name registration, you can also use customized domain name (You can input your
self-defined domain name.) After successful registration, you can use domain name to login installed of
the device IP.
 User name: It is optional. You can input your commonly used email address.
Important
 Do not register frequently. The interval between two registrations shall be more than 60 seconds. Too
many registration requests may result in server attack.
 System may take back the domain name that is idle for one year. You can get a notification email
before the cancel operation if your email address setup is OK.
