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 DVR 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 DDNS, you need to enable this service and set proper server address, port value
and domain name.

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.
