So I actually work in this industry cameras are easy to find but great tech support is hard to find. When selecting a system I always recommend keeping the equipment congruent (one brand). Use as little switches as possible , cable is just cheaper to run and doesn't go bad as often as a switch. A standard NVR will do fine, you don't need (Luxriot EVO) for your home is just over kill unless you have a compound lol. I have plenty of recommendations that can answer all your questions, get you a system, tech support ect. I not try to do any marketing / advertising here so just ask me for help if you are still looking for a solution.
