I just bought a WiLife system. The starter set with all the software was about $250 and each additional camera was about $200. (Purchased from ProAdvantage, you can also find this link on WiLife.com Online Retailers section). This camera gives very good video as long as there is some light in the area. The outdoor cameras can use an IR illuminator and makes seeing outdoors even better. I personally purchased 6 cameras total for about $1200. As far as setting up, it uses HomePlug technology and there is no need to run additional wires, it uses the electrical wiring already in your home. You can also monitor it while you are away by accessing your cameras on the WiLife website. WiLife was just purchased by Logitech and has gotten even better since. You can also get the Platinum option for about $80 a year that lets you playback recorded video while you are away. It only records motion as well, so you're not going to be watching recorded videos that don't have any motion.
