Back in the day, every concert ticket used to be stamped with a warning that record “NO CAMERAS OR RECORDING DEVICES!” If you tried to sneak in a camera, it could be confiscated.
But whenever you to a gig these days, the crowd is a sea of smartphones with people watching the show through their tiny little screens. This drives performers nuts.
This brings me to US patent 9,380,225, which was granted to Apple. It describes “[infrared] transmitter[s] can [that] be located in areas where capturing pictures and videos is prohibited (e.g. a concert or a classified facility) and the transmitters can generate infrared signals with encoded data that includes commands temporarily disabling recording functions.” In other words, these signals jam iPhone cameras.
Think this will fly? Don’t count it out.
