Will be installing a outside surveillance system sometime within the next year. I think I want an NVR system with 6-8 Dahua cameras. I have bought nothing yet, just been reading up. There is a brand new NVR for sale N52B3P4 16 Channel for $200. I have a few questions. Is this model too old for the cameras being sold today. Do I need to be concerned about the model/firmware of the NVR like the cameras (china, usa, international). This is my first install. Thank in advance for your input.
