The Closed Circuit Television system or CCTV is essentially a closed circuit that does not allow data transmission for public view. Security closed circuits can control and manage receivers connected to a camera. They can be wired or wireless and are frequently used in professional spaces, where surveillance is demanded – usually by law. It is considered necessary for banks, Casinos, airports and military bases to survey their spaces with closed circuit systems. The constant increase on security systems has raised discussions on public safety versus private life. At industrial spaces, CCTV equipment is necessary and can also be used for remote controlling.
