It's not too hard to set up once you understand how to do it. The system at our camp has grown to twelve cameras and has been exceptionally reliable. Much better than the old guy who used to go around pulling cards, forgetting to turn cameras on, putting in full memory cards, chasing game, etc. :)I'd love to get about 3-5 cameras hooked up to my phone, but looking at over 5000 replies doesn't give me a warm fuzzy about trying to do it.
