Student's class topic about "Security Camera" "Security Camera and Security Camera System" Security cameras or closed-circuit TV (CCTV) was initially developed as a means of security for banks. Today, however, it has developed to something more than just surveillance used for commercial purposes. The technology of security cameras these days have become simpler so that they are inexpensive enough to be used in home security systems and for everyday surveillance. Development of Technology The first security cameras used in public places were crude and conspicuous. They used low definition black and white systems without even the ability to zoom or pan. Advances in technology led to more sophisticated systems which became the precursors to the modern security camera. Today, security or CCTV cameras use small high definition color cameras that can not only focus to resolve minute detail but also semi-automatically track down objects by linking the control of the cameras to a computer. For instance, a typical modern security camera can track movement across a scene where should be no movement. It may also be able to lock onto a single object in a busy environment and follow it. Because the system is computerized, it is now possible to let this tracking process work between cameras. In the United Kingdom, specifically in London, security cameras are used in combination with computer imaging systems to track car number plates. This is a security measure taken by the government in case of an instance of crime, such as car-napping. Information from security cameras on car number plates are also used to generate billing information. The latest development in security cameras, aside from the new imaging techniques, is computerized monitoring. This allows the camera operator to run more cameras since he no longer needs to endlessly look at all the screens. The computerized system of this new security camera tracks the behavior of people, searching for any particular types of movement, particular types of clothing or baggage.
