"benitos"

We have a CCTV cam (Bosh WZ18) that is 1500 feet from the LCD display.

The cable that was used is a RG59 and having 2 splices (2 junctions).

The video signal is poor , we can see tha image but with lines and
it's noisy.


** That sounds like you have a ground loop in the cabling passing noise into
the shield of the RG59.

Your 24VAC may well be the source.

Or possibly injection from AC power cables running along with the RG59.

Whatever, the pic should not contain noise or lines.
