It is very difficult to know how stole something in a shop with all these people in it, also it is difficult to know how roped a bank when the bank is closed. However, in the information age, it is possible thanks to CCTV. The term CCTV stands for Closed Circuit Television. As its name indicates, Closed Circuit Television (CCTV) is a system in which all the elements are directly connected by cables, wirelessly or by infrared beams in a closed circuit. The CCTV system consists of camera, lens, monitor unit and a digital video recorder (DVR). It is an electronic system that captures images, and transmits them to another location for viewing and/or recording.
The camera captures the image and transfers it back to a monitor. The camera needs a lens to be able to focus on the subject. Because employers cannot always have a dedicated person to sit and watch the monitor 24/7, the images captured needs to be recorded. So, the digital video recorder is needed to store the images on to a disk drive in the same way as a home computer stores data, so that it can be viewed later.
The most common use of the Closed Circuit Television is securing the retail shops, government buildings, hospitals, banks and surveillance of traffic and airports. Moreover, every bank ATM (Automatic Teller Machine) uses CCTV to record the customers making their cash transaction. It might be interesting for you to know that there are more than 4000000 CCTV cameras in the UK and someone is likely to be caught on camera 300 times a day
