DDNS substitutes a network identification number for one that's easier for humans to use.
For Internet users to access your computer, they must know your IP address ¡X for example, when you run your own Web server, or use your router to make a VPN connection. Since the IP address changes, your Internet users will need to keep up with the changes. (As an analogy of this problem, imagine that your telephone number frequently changed without warning. Your friends would always be phoning the wrong number.)
DDNS solves this problem. The company creates an account for you that register an unchanging name, such as myname.company.com, and it automatically substitutes the current IP address ¡X no matter what your ISP has changed it to. For remote user access, you must also configure your router for port forwarding ¡X for services you make available on your computer.
The PIXORD DDNS (Dynamic Domain Name Service) can be
used when the user wants to access PIXORD NC with an
easy memorized name such as http://demo.ddns.pixord.com
instead of http://61.220.235.172 . This service
is useful when the PIXORD NC is located behind Dial-up
ADSL and IP sharing devices, which don't have fix IP
addresses and accessing the Camera server won't be easy
since their IP addresses will change for every reconnection.
When the DDNS service is active in the PIXORD NC, it
registers to the PIXORD DDNS server with its settings,
such as server name, router virtual port number and
updated frequency, and so on. Using a fixed frequency,
the PIXORD NC automatically updates the settings to
the PIXORD DDNS server. So even if the IP has been changed
because of the reconnection, the PIXORD DDNS server
will be updated with the new settings.
Once the name is registered, e.g. ¡§demo¡¨, accessing the camera can be done by simply typing http://demo.ddns.pixord.com .
Note: The PIXORD DDNS service is proprietary, which only works with PIXORD DDNS server and PIXORD brands of products.

| 1 |
Dynamic DNS Activate : Click to activate PIXORD DDNS service. |
| 2. |
Device Name: Assign a name for the camera that will be used for the DDNS service |
| 3. |
Dynamic DNS Sever Address : Specify address of PIXORD DDNS server, and the default is ¡§ddns.pixord.com¡¨ |
| 4. |
DDNS Connection Port : Specify PIXORD DDNS server listen port, and the default is ¡§80¡¨ |
| 5. |
Router Incoming Port : Specify your router listen port
for PIXORD DDNS server to redirect. The router
may configure the different port for incoming
(Internet request) and outgoing (Intranet
request), e.g. it may configure to redirect
Internet HTTP (port 80) request to Intranet
port 8000, then, in this case, we must configure
the ¡§Router Incoming Port¡¨ to 80, and inside
the PIXORD NC Network settings should set
HTTP port with 8000. |
| 6. |
Update Time : Specify the PIXORD NC updated
frequency in seconds, the default is 600 (10
minutes), this is the interval that the PIXORD
NC will automatically send to the PIXORD DDNS
server. |
|
DDNS message : Returns messages from
the remote PIXORD DDNS server, and displays some hints
which will help to diagnose the reason why the registration
fails.
-ddnsaddr CGI fail : It means that PIXORD NC can't communicate
with Internet. Make sure your Network Configuration
has the correct subnet mask, default gateway, and DNS1
setting.
-Already registered : Another user had registered this
name; please change your register name by changing ¡§server
name¡¨.
Example:
How to Setup a PIXORD200 (IP address 192.168.0.200)
behind a dialup ADSL router, access it by the name http://demo.ddns.pixord.com
.
Configure the ADSL router with PPPoE enable; Lan IP,
192.168.0.254; and subnet mask, 255.255.255.0. Assign
the ADSL router's virtual server with service port 80
to server IP 192.168.0.200. Configure PIXORD200 network
configuration with IP address 192.168.0.200; subnet
255.255.255.0; DNS1 with valid DNS address such as 168.95.192.1
or 168.95.1.1; gateway IP address with 192.168.0.254
(router's IP); HTTP port with port 80.
Configure server name with ¡§demo¡¨.
Configure DDNS with Activate; Address ¡§ddns.pixord.com¡¨;
DDNS with port 80; Router Incoming port 80; and update
time with 600 (10 minutes). Finally, click on submit.
If DDNS message success, then enter URL http://demo.ddns.pixord.com
on browser. Consequentially, it will show PIXORD
NC's home page.
