Almost everything that would normally connect to the computer, such as keyboards and mice, have become wireless for a good reason: fewer cables and more mobility. If you want cameras that integrate into your local network and do not involve a mess of cables, wireless IP cameras are the best solution. They are very simple to install, and all you have to do is open your browser on a computer in your network to configure them.
Open up your preferred Web browser.
Find the IP address of the camera. This address must be written somewhere on the device or on its operator's manual.
Write the IP address of the camera on your browser's address bar.
On the page you arrive at, set the camera name to something you would be able to distinguish on your network.
Browse the interface until you find a menu where you will write an administrative ID and password.
Type any ID you would like to have and a password for the ID to log in through. This is necessary so that others cannot tap into your camera and invade your privacy.
Open the browser interface for your camera (see the section called "Getting to the Web Interface").
Go through the menus until you find where you can set an IP for your camera.
Manually assign an IP that you will recognise for your camera, and set the default gateway to your router's IP address (find this out by looking at your router or its operator's manual). Make sure that the IP of your camera is not already used by another computer.
If you already run a web server on port 80, change your camera's web port. Find out how to do this by reading your camera's operation manual. Each camera has its Web server settings in a different place on its configuration interface. Consider getting a dynamic DNS for your computer so you can connect easily to your camera's Web address without having to remember your computer's IP number (see "Dynamic DNS" in the "Resources" section). This means you will be able to type "mydomain.somednsprovider.com," for example, instead of memorising a sequence of four numbers in your IP address. This is also very useful for Internet connections that do not have a static IP address. Since IP camera configuration pages are not uniform, it is best if you read the operation manual for your camera before following these instructions so you will know where to find anything.
