Quick 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 quick DDNS works with the device
from the manufacturer so that it can add the extension function.
2) Function Introduction
The quick 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. User may also use customized valid domain name (has not
registered.).
3) Operation
Before you use Quick DDNS, you need to enable this service and set proper server address, port value
and domain name.
Server address
：
www.quickddns.com
Port number
：
80
Domain name
：
There are two modes: Default domain name and customized domain name.
Except default domain name registration, user may also use customized domain name (User may input
your self-defined domain name.) After successful registration, user may use domain name to login
installed of the device IP.
User name: It is optional. User may 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. User may get a notification email
before the cancel operation if your email address setup is OK.
