Hi all
I'm looking for a replacement Pan/Tilt/Zoom controller for a survelance camera. The existing one is an RCA TC4501 which is old and not longer made. The zoom control is not working, switch is fine, but I can't find any documentation or schematics for it.
Can anyone advise me as to a unit that can replace this controller. I don't know how it works, the only cable between this controller and the camera is the video cable, so the signals must be super-imposed on the video cable back to the camera.
Thanks
