I have two of these that I use for checking active bird nests on towers
before we climb up to do work. They work off my iPad and iPhone and are
pretty slick with a 720p video cam in front and a still cam in the bottom
but the battery lasts about 10 minutes and it's done. Time to bring it to
Other than that it's a great piece of equipment. When you turn it on you
even set how high off the ground you want it to start. So it pops up to 4'
(what I have it set at) right off the bat. It's not effected by the winds
for sure. I live on the ocean.
