The video is well worth your time. The device works very well, and the fart spray has a purpose, in that it encourages the thief to ditch the package as soon as possible, enabling him to recover and reload it.
Presumably the last thief never disposed of the package and was therefore the only one to discover the cameras. I wonder what they were thinking, and if they'll come across the video. Wouldn't be surprised if so, it was on the front page of Reddit yesterday.
