webcams are way cool, I dont have one, so I cant recommend one.
Best way is to maybe check yahoo and look at a few webcams, and if you see one with a good quality picture, just ask them what kind of webcam they are using.
My favourite webcams to check out are these ones. http://www.ev1servers.net/english/dc/webcams.asp
I'm not sure about that one but I have the Logitech ClickSmart 420 which has motion detection monitoring and allows you to set up web site as well as a few other things. Each part is set up step by step through the Camera Control Centre. Good luck with yours!
