Hi dear all, i have some experience with old analog system, but now because of low prices of ip cameras and nvr i think to make simple home surveillance system(good chance also to learn something new). My questions are: - Is N6200-9EH (HI3535 chipset) NVR compatible with 720p camera (1280x720) ? - Which one to choise N6200-9EH or N6200-8EL (HI3520 chipset), my all camera will be 720p or 1080p .
