Military UAV
This UAV could be yours for less than £300!
UAVs such as these will be a cool toy to many people, but there will be others that will purchase these spies in the skies for more sinister purposes, and not just for spying on the neighbours. These UAVs aren't as easy to spot as you might, newer models are bound to be even more covert, and even when spotted few will realise they have quality video cameras on board watching them. They do make a good recognise tool for would be thieves targeting business premisses, and I wouldn't put it past the odd social engineer and professional hacker to use such a tool to help build information about potential targets as well.
Not easy to spot as you might think
