“We are rapidly entering the age of no privacy where everyone is open to surveillance at all times where there are no secrets from government.” 1 —William O. Douglas, former US Supreme Court justice (1939–1975)

Another surveillance-related boost to crime prevention occurred in 1976, with the invention of couple-charged device (CCD) technology. This led to the development of cameras that could be used in low-light settings. These security camera systems used microchip technology to convert optical images to digital signals and led to the rise of round-the-clock video surveillance outdoors as well as indoors. CCD technology led to future innovations such as image sensors that used arrays of light cells to capture images. In 1996, Internet protocol (IP) cameras were introduced to the surveillance arsenal. Many security professionals felt that these devices represented a sorely needed improvement over the old CCTV cameras, since they did not use analog signals and coaxial cables. Instead, these cameras used digital signals and high-speed ethernet networks to send
