5.2 Dynamic IP Addresses
DDNS is a service that allows your IP Camera, especially when assigned with a dynamic IP address,
to have a fixed host and domain name. This means that even though your WAN IP address is
constantly changing, you will have a fixed hostname you can use to access your cameras at all times.
You can access the camera directly from the Internet using the hostname and port number.
What is Port forwarding?
If you have never done port forwarding before, you can open and view the following link to
understand the basic concept. Port forwarding allows for outside connections to access a specific
device on your network from anywhere in the world. Every router automatically blocks any incoming
connections for safety purposes. Using port forwarding, you are telling your router to allow a
connection through a certain port (you can think of it as a gateway) into your router. You set this port
to a specific device, in our case an IP Camera, so it can be accessed from anywhere in the world.

How do we configure Port Forwarding?
For this section, we will be using an example:
Let’s say the camera’s LAN IP address is http://192.168.8.
100
:
2000
, and the Media Port is
9200
.
Step 1:
Login to the router,
and go to your router’s port forwarding or port triggering menu.
Sometimes this is also under the name of Virtual Server or NAT.
Using the Linksys brand router as an example, we would log into the router, and go to the
Applications & Gaming
menu. We would then click on the “Single Port Forwarding”
sub-menu.
Step 2:
Create a new column using the LAN IP address & HTTP Port of the camera within the router
as shown below, then push OK or Submit to save your settings:
