Background: I have a normal CCTV camera (650 TVL) . It requires a BNC cable in order to feed video signal from camera to DVR.
Problem The problem is I have only a single copper wire from CCTV to DVR. The wire which is to be used for the transmission has no shield. It is normal spare copper wire used for household electricity (AC). This is a spare wire and does not have AC current in it.
My Understanding I think that the two wires used in a BNC cable (one core and other shield) can be multiplexed and feed to a single wire
So my question is can I multiplex the signals of two wires of a BNC cable, transmit over a single copper wire and at DVR side reverse the process (i.e. demultiplex the signals and feed to DVR)
Will this work? If yes then can someone please give a head start on how to proceed in order to make or buy such mux/de-mux.
