Yeah... its for copyright issues at concerts and movies... right...
Read more about this at the following sites:
For example, an infrared emitter can be located in areas where picture or video capture is prohibited, and the emitter can generate infrared signals with encoded data that includes commands to disable the recording functions of devices. An electronic device can then receive the infrared signals, decode the data and temporarily disable the device’s recording function based on the command.
So that might be OK … assuming the technology is only used at concerts and doesn’t extend to, like, disabling phone cameras during instances of police brutality and/or sociopolitical/religious unrest. If my concert experience has to suck in order to see and hopefully prevent the next Oscar Grant, Eric Garner, or Walter Scott from being killed in the future, then so be it.
