Is the reverse camera signal ground actually a shield?

Won’t bore you with the details, but I need to make off the signal cable again on my optimill reverse camera. Will there be 2 cores in the cable or 1 core and a shield? If it’s the latter, does anyone know if that’s a foil shield or a braided shield?

Cheers

When I installed my reverse camera, I did not have a phono cable that was long enough, so I simply cut the one I had in halve and spliced a 2 core in the middle. The video quality was not any worse than when I tried it with a the proper shorter phono cable.

I think the ground was also a shield on the original cable. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Thanks Dinnu. So is there just the 2 cores, or 2 cores and a shield?

Just to be clear.. my camera is not optomill, and just use a standard video jack (phono). It is the phono cable that connects between the camera video jack and the monitor video jack that I extended. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Normal composite video (as reversing cameras usually are), is just a centre single core with the signal on it, surrounded by the shielding jacket (braid or foil)

I can confirm that the optimill camera is just a 2 core cable, no shield.
