How does a CCTV system work?
Closed-circuit Television is a particular setup of cameras used to transmit video data to a particular place on some limited number of monitors whereas Broadcast Televisions are transmitted openly. This setup is present mainly in places which need surveillance like banks, airports, railway stations, hotels, schools, shopping malls and nowadays also in our homes.
A government cannot employ such a huge numbers of cops to be in the right spot at any time of the day, the job of a CCTV setup is to reduce the workload of cops. But it needs a strategic angle of thinking to set up a particular CCTV camera in a particular spot. Installing the cameras anywhere would not help. It has got the name as “closed circuit cameras” because the data made by the cameras runs through private coaxial cables or wirelessly to a particular control room to be monitored by a small group of people.
