BNC Female to RCA male connector. One end has a female BNC jack and the other end has a male RCA plug. These will convert a male BNC plug into a male RCA plug, or they will convert a female RCA jack into a female BNC jack. If your video signal is from a BNC plug, such as security camera, but your monitor or TV input is RCA, or you want to convert a RCA plug into a BNC signal, this one really helps you.
