If you want to keep it simple, reliable, and go the most cost effective route an IP camera is it. One wire and direct network (PC & Internet) connection with software included to do pretty much anything one would want.
I could set it up from here. All you need to do is the physical labor part.
When you are ready to go ahead with the project, PM me. There is no sense figuring it out all a year ahead of time since this stuff is constantly improving and getting less expensive.
