You might think that you have never been on TV, but you are wrong. CCTV (closed circuit TV) cameras are everywhere! They are in shopping centers, at ATMs, outside buildings and even on our roads and motor ways. They are operated by the police and private security companies. By capturing criminals on film they hope to discourage crimes such as mug goings, shoplifting and carjackings. They also watch the roads for people speeding,and more. In some buildings there are even cameras in smoke detectors, clocks and exit signs. They keep track of where you are and what you are doing all day, every day
