WHAT IS AN RF MODULATOR?
It is an interface that converts audio and video signals to a normal VHF TV signal.
This product converts audio and video signals from a video output source into VHS TV signals that can be viewed on any television set.

WHY WOULD I NEED ONE?
Allows you to connect a DVD player, Camcorder, or other Game machines to an older TV without audio/video inputs. When used with a security camera, it means that you can use a regular TV as a monitor.
