4 Configuring the Camera for Access from the
Internet
You can configure the camera to be accessed over the Internet, allowing you to view camera images and
change camera settings from anywhere—even using your mobile phone. This section explains the concepts
and procedures for configuring your camera (and other network devices) to allow you to view camera images
over the Internet.
Before you can configure the camera for access from the Internet, it is necessary to understand how IP
addresses and Internet connections work.
Understanding local addresses
Each device connected to your computer network (PCs, router, network printers, network cameras, etc.) has
an IP address. It probably looks something like this: 192.168.0.100. Each IP address on your network must be
unique, as shown in the example below.
In this example, you would enter 192.168.0.253 or 192.168.0.252 in your web browser’s address bar to access
your cameras with your PC.

Although each IP address on your network must be unique, the addresses are unique only to your network. In
other words, your cameras and your neighbor's cameras may have the same IP addresses. In the example
below, the addresses of your devices (on the left) and the addresses of your neighbor’s devices (on the right)
are the same, but this is not a problem because the cameras are not connected to the same network.

IP addresses that distinguish different devices on the same LAN (local area network, i.e., personal network)
are called local IP addresses. The IP addresses in the examples above are local IP addresses.
So how can you access your camera when you are away from home if other people are using the same IP
address as your camera?
