That will definitely limit my receiving end of the project.
As far as NTSC cameras with output wires of red (power), black (ground), yellow (video), is this the same for all NTSC cameras with just three wires with a similar configuration of power, ground and video? Is a composite camera always an NTSC camera? If not, is an NTSC always a composite camera? I see the two often together when I am searching for the cameras. Either way can a composite camera have more than three wires for only the power, ground and video (no audio)?
