Default Video signal from CCTV cameras??

You say power is live/neutral. Are you sure it's not DC? If it's DC, then
one of those supply wires will be the ground and you have to bring that out
to both the audio and video shells. If you get horrible hum, just do it to
either audio or video but not both. Alternatively, is that audio wire really
audio or could it be video ground? Do you definitely have audio on those
cameras?


Strange...I connected the ground from the power supply to the shell of
the plug and still get no clear video picture. I'm pretty sure that it
was the correct cable, as this one was originally connected to the
outside casing of the modulator.

Is there anything else that I could've done wrong???
