Wow. Thanks for all the replies. I had checked back a few times and thought nobody was replying, before I noticed that my post was moved.
The things that sounded most interesting were:
1. Swann 4 channel suggested by ver0776 - You didn't mention much about setting up intranet viewing. Does that mean you can't do it, or it's really easy with included software. I'm guessing it's one extreme or the other.
2. If I did the USB webcam thing, how do I make that video available to other computers in my home besides the one it's physically connected to? Is this a real option, or just a fun thought that you could piece something together for very cheap? Is there software that can do motion detection and recording with these? Are there nice ir cameras as well, or just the cheapo ones?
3. The LukWerks system sounds incredible and ideal for my situation. My big concern is about the cameras. Looks like they just have one camera you can use, and they're a little expensive. What is the quality of the image like? How does it perform in the dark. Does sending the video over the power lines really work that well? Does it matter if the outlets are on different breakers?
4. Will check out electron's review of the nv5000, but not sure if the incremental cost will be worth it for me.
Would really like to hear back from CannonG about LukWerks. You don't work for them, do you?
