Please see attached. Basically 3 cams are way out in the backyard. I dont' want all 3 cat 6 cables going to the house. I want one. So wondering if I connect them to a 4ch switch then connect that (only one cable running to the house) switch to an 8ch switch? If not what do I need to achieve only one cable going to the house with 3 cams out in the backyard and more cams in my home?
