Wireless Networking with Nikon Cameras
DRAFT #4
Wired Network
In a simple wired network each computer has a wire coming from the back to a 
central “hub.” Each hub is then wired to a larger box called a “router” that routes 
signals from hub-to-hub and computer-to-computer. The router may be connect-
ed to (or may also be) a “gateway” which, as it sounds, allows the local network 
to connect to different, outside networks.
The “1’s and 0’s” that make up the language that the computers speak travels 
up and down these wires from computer to computer. The router and gateway 
determine if the signal is destined to a computer on the local network (called a 
“LAN”) or if it should be routed out, through the gateway, to the larger network or 
“WAN” (Wide are Network).
Wireless Network
A wireless network is exactly the same as a wired network except that there is no 
wire from the computer to the hub. Instead, a “Wireless Access Point” is connect-
ed to the hub and a wireless “transceiver” (transmitter and receiver) is connected 
to the computer. The transceiver converts the network 1’s and 0’s into radio 
waves (in the 2.4GHz frequency range) which the Access Point receives, decodes 
and passes on to the hub and the rest of the wired network.
IP Addresses
Just like each house on a street has a unique address, each device (computer, 
camera, router, etc.) on a network must have a unique network number. This 
number is called an Internet Protocol Address or shorter “IP Address”. An IP 
Address is a group of numbers that looks like this: “192.168.1.234”, while the 
full description of IP Addressing is beyond the scope of this document the basics 
must be discussed.
As mentioned above each device on a network must have a unique (different) 
number. Not only does the number have to be unique it has to be part of the same 
network or subnetwork. Without getting into too much detail the first three parts 
of the address identify the network and the last part of the number is the indi-
vidual network address. In the example above the “192.168.1” is the network and 
“234” is the device address. Much like a house is located at “1600 Main Street” 
where “1600” is the unique house number the “Main Street” can be though of as 
the network the house is on. So a group of computers or cameras on one network 
all need to have address similar to:
192.168.1.150 - Computer 
192.168.1.151 - Computer 
192.168.1.152 - Camera  
192.168.1.153 - Printer
Notice how the first three parts of the address are the same, only the last group of 
numbers changes. If set up properly like this each device above would be able to 
communicate with each other. The first part of the address may change depend-
ing on where the IP addresses are coming from (more on this later) but as long
