I have a simple install because I am doing this the first time and only need monitoring of my home certain times. I ran the ethernet cat 5 e from the six cameras to a switch located in the garage, then one Cat 5 to the NVR, located in a different area. Followed the Andy Youtube instructions. Still trying to figure the motor vehicle alarm setting because it counts the cars up to 99 on the NVR and I haven’t figured out how to turn that off, when I am not recording. Time will tell if this is a good sytem.
