Gang, I've just finished a full product review on the CV0204DVR by SVAT. This is a pretty sweet system for under $600 dollars.

The system comes with 4 cameras that can see up to 15 feet in complete darkness. Plus you can access your cameras or the DVR recordings over the internet at anytime.

SVAT has also made this system RoHs compliant. This means they have made an effort to reduce the hazardous material in the making of the equipment, great for you and I and great for the planet.
