BNC CCTV power and video connection

[davycc]

Hi all,

Sorry if this is a stupid question but any help would be greatly appreciated.

Have "inherited" a Kguard SHA 104 system which is working perfectly. Unfortunately to run the cables from the cameras to the unit I had to snip the cable before the split for power and video. I am now ready to re connect the cable bot find that along with the red power and yellow video there is what seems to be a common un-sheathed copper supply running as well.

Quest is do both poer and video require this cable or just power or video?

Also I may need to use new BNC connectors and if they require both the yellow and the bare core copper wire, which go where in the BNC ?

Hope this is clear.

The yellow will be video so goes to centre of bnc connector
Bare copper will be ground(ov) to outer of bnc

Thanks for the reply, heres a pic of the old BNC. So bare wire goes to both video and power
