Looking for computer recommendations for home video surveillance.?

I'm looking for a way to get webcams or the like and use them for home security purposes.

I figure that I could get a computer that has several usb ports or equivalent and it would be dedicated just for that purpose. I would use a broadband connection to stream images off-site (not all the time), have a UPS (10-15 minute duration). I'm thinking of 4-6 cameras being managed by 1 software package.

I'd like the cameras mid-range - a ccd or low light camera probably isn't needed, unless that would be the preferred tool for the job.

So basically, I'm looking for the computer, software, cameras and UPS. I don't need comments on home networking or bandwidth. Computer size isn't an issue, it will be tucked out of the way and not moved (racked, probably). Operating system isn't all that important (unix would be preferred but not necessary) The cameras can be either fixed or movable - I haven't really figured out how I want to lay them out yet.

Suggestions?
