I acquired an old black and white Magnavox MC 3511 CCTV camera (old meaning it uses a camera tube) which runs off phantom power. The only connector is coax style like a car radio antenna but smaller. I removed the connecter and applied 12vdc and coupled the video output through a
2200uF cap in parallel with a .1uF ceramic cap. The format is RF and switchable to channel 3 or 4.The overall picture quality is pretty bad. Lots of ghosting and distortion and some scan lines going diagonally. What is a better way to couple the RF out? Should the capacitor sizes be any different, should there be some type of choke in series with the incoming power? To answer the least of my questions, what voltage does this camera take? Varying from 9-13vdc gives different results none of which look very good.
