In 1976 Murray Tovi introduced the first discreet cctv surveillance system to the security industry (US Patent 4,225,881) Within a relatively short time it would dominate the industry. The generic change from visible camera systems to discreet ones hidden within two-way mirrored capsules accomplished two things: It deprived a would be shoplifter, terrorist, etc. of the direction of the camera in the capsule, and; It softened the presence of cctv surveillance for the customer, etc. In a next generation technology (US Patent 4,934,792) discreet surveillance may give way to invisible surveillance for the following two reasons: It deprives a would be shoplifter, terrorist, etc. of the exact location of the camera system(s) and; It virtually eliminates the presence visibly of a cctv system, visible, discreet or otherwise for the customer, etc. The system is based on a new type of two-way mirror that enables a reflective characteristic indistinguishable from an original painting, photograph or printed graphic while allowing total non-distortion of transmission or see-through. Its use in a retail store would blend in with all the graphic material on the walls: signs, photos, posters, promotions, etc. It would be impossible to know which holds a sophisticated pan/tilt /zoom camera assembly behind it.
