It works. The DVR does it's job and it's pretty easy to set up. I purchased a panel from Monoprice to handle the electrical from each camera. Also purchased the connectors from monoprice. Purchased the cable from sewell.com.

I only have one complaint. The cameras are not very good resolution. They are 700tvl and I guess that's the industry standard but they don't see license plates or a good clear view of the persons face unless they are 5 feet away. All my cameras are at work and the distance is about 20 to 50 feet viewing. So if you are not recording that far away then you might be fine.
