[QUOTE="bassman, post: 82060, member: 1514"] Isn't the neutral & earth common back at the receiving end so the potential will not alter. Bow to your expertise knowledge. Most of the systems I have worked on 20 to 50 cameras across site on high mast external systems,various forms of transmission back to monitored point,via hard wired fibre optic or co-ax in ducts. Only problem so far is vermin chewing cables. Fed from various sources non ups or surge protected, only problem is backward EMF. Please their is no expert on any system be it CCTV or Fire. Horses for course's(Vets excluded) [/QUOTE]
