Paul server guy writes "I am building a limousine bus, and the owners want to prevent occupants from using cameras on board. (But they would like the cameras mounted on the bus to continue to operate; I think they would consider this optional.) They would also like to do it without having to wear any 'anti-paparazzi' clothing (because they also want to protect the other guests on board), and without destroying the cameras. (So no EMP generators, please). We've done some testing with high-power IR, but that proved ineffective. Does anyone have any ideas that they are willing to share?"
