The all in one camera/web server packages aren't all that great.
If you have a decent video capture card in your computer you would be better off getting a higher quality camera. You can run the video(coax) up to 1000feet. Look for a camera that is color when there is light and switches to B/W during low light conditions. www.supercicuits.com has a good variety of cheap stuff or you could try commercial CCTV cameras like sony or JVC. I prefer the "cyberdome" camera made by www.kalatel.com or the "spectra series" from www.pelco.com but you'd be looking at 2-3k for the camera alone.
