I am looking for an NVR that can handle 60 cameras. Currently the cameras are older Panasonic 720p cameras and I am thinking about replacing them with Hikvision h.265 cameras. I have been looking at the DS-96064NI-I16. I have not dealt with a system this large before and the needs of the system are pretty basic. Anyone have experience with this NVR or suggestions for another NVR?
