Though flight distance is only 50 meters the camera can extend the usefullness of that distance. This might be a good tool to see what's going on in a distant or obscured area of your property, or to check on a neighbor if you've worked out that kind of arrangement. See the video below to get an idea of the kind of pictures you'll get.
I forsee the prices coming down on these and their usefulness as crime fighting tools increasing.
This one is even cheaper and has great reviews:
