Hi I would like to convert a cctv camera to a duct camera I am using a cheap 9 inch monitor, and will be soldering the red black and yellow wires to a 3 pin female plug with a 12v 1a power supply, I will be using a dome cctv camera by opening the camera and cutting the wires and connecting red wires together same with the black, yellow remain, so no connectors! I brought 15 m of cctv cable which has red and yellow wire plus a bare wire, will this work if I connect relevant colours together and bare wire to the black, on the other end I will be connesting the male 3 pin plug. Thanks for your help
