Chapter 6. Accessing the Camera over Internet
N300 Installation User Manual

The router configuration is complete.
IMPORTANT!
You can use the virtual server to redirect the HTTP ports (for example, the port 80 of the camera 1 is
translated to 8080; the port 80 of the camera 2 is translated to 8081). However, you must specify a unique
RTSP port number for each camera. It must be directed to the same port (for example, the port 10000 of
the camera 1 is translated to 10000; the port 10001 of the camera 2 is translated to 10001).
To access the camera over the Internet, use the IP address provided by your ISP (the IP
address of the router’s WAN port) and a certain HTTP port number.
For the provided example, the WAN IP address is 77.108.73.169 and the HTTP port
number is 8081. Therefore, you need to enter the following in the address field of your browser:
http://77.108.73.169:8081/.
To use several cameras, you need to specify a unique port number for each camera and
configure the port forwarding.
6.4. Accessing the Camera over the Internet Using DynDNS service
6.4.1. Overview of Internet Access Using DynDNS service
If a computer is assigned a temporary IP address changing from one session to the next, it
means the computer is assigned a dynamic IP address. Mostly, ISPs provide users with this type
of addressing. However, in order to have a permanent access to a device over the Internet, you
need to get a static IP address from your ISP, or use a Dynamic DNS service (DDNS).
The Dynamic DNS service allows you to make your cameras accessible over the Internet
even though they are assigned a dynamic IP address, which changes from time to time. All
external users can always access the camera using its domain name.
The domain name, such as www.camera1.dyndns.org, is used to access your camera over
the Internet instead of an IP address.
To do so, create an account on the DDNS server website such as www.dyndns.org, enter
your camera’s current IP address and choose a domain name that will be used to access your
camera.
When either the IP address is changed or a new connection is established, the ISP assigns
your camera a new IP address. Then the camera’s built-in software processes it and sends to the
DDNS server. The DDNS service provider ties this dynamic IP address and the domain name you
chose before.
For this example, we use the following DDNS provider: www.dyndns.com. The procedure of
taking a domain name is similar for different providers. To access your IP camera using a domain
name follow the steps below:
