I have the Iris system from Lowes and I installed a Lorex 4 camera system that is expandable to 8. I have 500 watt halogen dusk to dawn lights tied in with double led flood light (more precise targeted light) at the corners of my house. The Iris system is nice and very expandable down to being able to do a dog door and water overflow monitor. The camera system was on clearance for 179.00, it is no top of the line system but works for what I need. The lights keep the cameras from going into night vision black and white mode.
