Thanks for the fast reply!
I was thinking of getting a dedicated PC. The areas I want to cover are my garage and front door with one camera which would be an area of about 7 meters x 5 meters and my back yard of about the same size. I only wanted to spend a couple of thousand dollars but if it was going to make a hugh difference in quality I could probably strech a little more. Sorry, don't have any pics at the moment.
