I ran across the Lily Camera Drone today. It’s waterproof, has a tracking device that lets it follow you. It records slo-mo, HD video, sound and takes 12mp still photos. This drone is automatic, you don’t have to control it’s every move. Yes, you could use it for surveillance but the applications are endless. It’s new and has not from what I can tell shipped yet. Go to the manufacturers web site if you want to pre-order one. At $499, it packs a lot of value.
