CCTV uses video cameras to send a signal to a particular place. There is always a limitation on the number of monitors. CCTVs are useful in many places like banks, schools, shops, casinos, multiplexes, airports, government buildings, railway stations, corporate houses, building, ground security, traffic monitoring, home safety etc. CCTVs are very useful in Industries where the environment is not suitable for humans. The CCTV cameras help in observing the process from a control room where CCTV monitor is placed. These CCTVs can be operated around the clock, or they can be operated for a particular period of time.

Modern CCTVs have video recording facility. This helps in storing the record for many years. They also have the facility of sending mails to alert the users.

In olden days, a continuous monitoring was required of these surveillance systems. Also there was no recording facility available. Gradually magnetic tapes were developed which used to store the records. But these magnetic tapes had their own disadvantages. They need to be changed manually, which was expensive and unreliable. Slowly digital multiplexing was introduced. Which helped in the usage of CCTVs. Recently, CCTVs have a new technology. They are now internet based systems and are very helpful in day to day life.
