Quadcopter perches itself on an electric wire or a telephone pole, or at the edge of a roof, looking at the entrance to your building. When someone gets close it takes off to get a better picture. If it's late at night or your alarm system went off and wasn't canceled it will follow the burglars and their car to their location and stay guard over there.-- pashute, Jun 30 2016 Mobile accessory to your alarm system? You have seen the future, congratulations [pashute].-- normzone, Jun 30 2016 From my window here, I can see the fuchsia.-- MaxwellBuchanan, Jun 30 2016 random, halfbakery
