ABSTRACT:
A system and method of detecting and thwarting the use of unauthorized imaging systems at theatrical performances. Sensors are deployed at a theatrical event to detect the IR focusing signal and/or the RF signal of an unauthorized imaging device. De-focusing signals are used to disrupt the auto focus system of imaging devices that do not use IR focusing systems. A thwarting signal comprising invisible light frequencies may be combined to produce a thwarting signal that is received by the CCD of an imaging device as white light thereby rendering the recorded image unusable.
