systems that have proprierty wiring are just too expensive and everything has an extra cost. DVR goes down you cant just buy another unless the same but if you wanted to use or upgrade to something else you cant. not without extra costs.
most of the time these systems cost more than standard BNC
Well the writing isn't too bad , it is a RJ12 cable that has all of the Audio, Power, and Video in one. Also you can interchange it with BNC easily. Its plug and play and easy to switch cameras, and the cables and connectors are not too much either!
