But do have three iPhones, you can save a lot of money on a monitoring system by download Cloud Baby Monitor app to all devices ($3.99). What you do is use an old iphone (like an iphone 3) as your video and audio base. Then, you can use other iPads or iPhones as where you see baby. The great thing is there is no distance limit. I'm going to try it, and I thought I would pass it on.
