2.2.2 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 the HTTP Port NO.?
Default HTTP Port is 88
All cameras have the default HTTP port of 88. For example, if the LAN IP link of the camera is
http://192.168.8.102:88, this means that the camera’s HTTP port is 88. You can change port 88 to another port
if you’d like such as 2000 or 8090, which will not be conflict with other existing ports like 25, 21,10000.Here you
can set the port no. between 1 and 65535.
Change the default http NO.88 to another one.
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
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:
