Closed-circuit television, popularly abbreviated as CCTV, is a technology that uses video cameras to send signals to a designated place and set of monitors. CCTVs are commonly used for video surveillance of private or public spaces as a security measure.
Its history can be traced back to 1942 in Germany, when engineer Walter Bruch set up the system to monitor V2 rockets. It was the earliest recorded use of CCTVs. Seven years later, CCTVs were introduced for commercial use.
CCTVs are said to help deter criminal activities such as theft or robbery. The technology has also helped in identifying suspected criminals, by allowing police and authorities to get an idea of what the perpetrators look like. Here, we examine some facts and figures on CCTVs from all over the world, and get a glimpse of how this technology impacts our daily lives.
