Panasonic makes a series of network cameras. They would require the use
of a router, which you probably have if you have more than one computer
on the internet. This solution would be the easiest if you have the
existing network.
Do you have a network, and if not, are you comfortable with setting one
up? If you have a network, is it wired or wireless?
Also, if you can do me a favor and write your response in a word
processor then cut and paste is into the entry box so that you can
spellcheck your writing, it would make figuring out what you are asking
much easier.
If you don't have a network, then you are going to have a bit of a
problem with this project. You will need to have the computers
connected somehow.
