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 DVR 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. You can 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, 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.
