Home Security (take two) Windows or Ubuntu? Server or Desktop?

I've had a little experience with the security system setup from my last post, but I moved, and I'm going to try something different. Should I use Ubuntu Desktop or Ubuntu Server for webcam monitoring? I'm a Windows user who would like to eventually learn how to use Linux as well as i can use Windows. But in the meantime, I'm about to set up webcam monitoring in my house. I've got a few USB webcams, and one LinkSys wireless webcam. I'll obtain the monitoring software from a third party. I need an operating system that can handle processing four video streams as well as running the security software. (I'm also going to use remote admin software so that I can have a "headless" setup.) I'm currently running WinXP Pro (Corporate) on a machine with an A.M.D. Athlon rated at 1.02 Ghz with 2GB RAM. A friend of mine recommended that I use Ubuntu Linux, which I think is a great idea. The problem is that I don't know if I should use the Desktop or Server edition of Ubuntu. Also, since the rest of my network (and family members) uses Windows, the remote admin software I use either has to be cross-platform, or be Linux compatible with a web-interface. So should I use Ubuntu Server or Ubuntu Desktop? Or should I stick with Windows? Also, as far as the webcam security software is concerned, I need software that handles multiple streams and has options for motion detection, record on event, notification through email, and a web interface (HTTP server). Also, FTP options would be nice to have, but are not required. Any suggestions for this? (Win?/*nix)

Hi there, Have you had any response to this/ have you decided on a set up yourself. I'm looking into a similar setup. Currently running Ubuntu. Receiving a text is important. Any advice/ are you going to make an instructable?
