The Hammer


Simple tools have always been available in the fight against unwanted video surveillance including eggs, spray paint, and sledgehammers which can be used to disrupt the use of video cameras in surveillance.  However the problem with these devices is that they're extremely hands on and require the user to apply them to the surface of the video camera lens or it's covering.  This is a dangerous route, however fun it might be a person smashing a surveillance camera with a sledgehammer tends to attract attention.  With a discreet signal disruption device this becomes no problem at all.
