I just moved to a new city, and did a Google search for my address and have found that my apartment was broken into on Christmas Eve last year.  Now looking around the apartment, I could see where the door had been kicked in.
  Has anyone had experience with wireless HD video systems and can recommend a starting point?  I looked online and nothing stands out.
  I figure I'd have a dedicated computer that can be "hidden" and have it communicate via wireless to the Internet.
  Looking for something like this, but PC based and capable of multiple cameras:
