Been incredibly impressed with these Camera kits, having first installed in my parent's place and now mine we love the simple installation and ease of use of the system. It takes about a day or so to be able to route the cameras around and the quality of them is a quantum jump over our old 4 camera system - the reliability of the DVR unit is very useful and the cloud backup option to DropBox is a must if you are incredibly security conscious, I have my office window covered just in case!
