Bushwacker.....I found a complete set that suited my needs from these folks:

and then looked around online to find an outlet with the best deal. I have 2 different setups in different areas of my property so the needs vary. I put the dvr in a secure location (safe) so that even if the power is cut the cameras would catch the culprits before that happens.
They have a pretty good resolution even in the dark. The first setup was purchased on a Groupon deal and was half price.
If someone sees that you have security cameras, it seems word gets around which is also a great side effect.
