This CCTV adapter has a BNC female on one side and a male RCA on the other. The most common use for this adapter is to convert a BNC cable end into a male RCA composite in order to connect a cable to a television set.
We include one of these with most of our cables. We do this because our cables have BNC ends on them for video but some camera have an RCA jack for video. This adapter allow the camera to connect easily to the cable.
