CCTVs, also known as Closed Circuit Televisions, are used to send video signals to a limited number of televisions unlike the broadcast television, which is available to a large number of people. These are more located in airports, casinos, banks, jewelry shops, large stores etc. to discourage crime like theft. They are becoming cheap day by day so you might find them everywhere. Some people also place them in their homes to catch any intruder or so.
