What is an NTSC Video Monitor?

A composite monitor is any analog video display that receives input in the form of an analog composite video signal through a single cable — in contrast to multiple-cable or multiple-wire video sources such as VGA cable. A monitor is different from a conventional TV set because it does not have an internal RF tuner or RF converter that can receive signals from an over-the-air broadcast TV station; however a user can install an external device that emulates a TV tuner (e.g. VCR, cable box, etc.) . A video display that is a "monitor-only" is useful for security cameras, some computers, and many other devices.
