I have a digimerge 8 channel DVR with 5 lorex cameras and one monoprice camera. it has sent 2 people to jail and logged numerous bears walking through my yard.
the resolution is decent on the cameras, but I am going to upgrade the DVR to a 960H resolution 16 channel unit when funds permit because I want to be able to log license plates also
my setup is analog/wired. I have 2 on the back crossing over each other to capture the whole yard, 2 crossing on the front, 1 watching the back door below the deck, and one dedicated to the driveway. there is some redundancy, but more coverage is better in my book......
