Hi. I am not an installer, just an experienced end user.
I am moving a couple of analogue recorders to another location along the coax cable runs. In effect I am moving the recorders closer to the cameras along the coax. The coax is stretched along cable ladder trays along the roof. There are network, power and signal cables along the coax.
Tracing the cable by eye or hand will not work, because of inaccessible portions of the cable run. I do not know if all the coax is mine. And my cable is of different ages, so I can't just pick a type. I know that there are dead cables from earlier installations up there, so counting is also not an option.
I have tried toning with a fluke intellitone pro 200. But even with the cable disconnected at both ends, and connecting the toner, I only get a tone at the other end. Nothing along the cable. Just hisses from all the different cables.
As a last resort, before starting to pull all the cable back towards the new location, I was thinking that I could try to "tap" the signal from the cables. I only need to be able to verify that the signal is from one of my cameras, so quality of the image is not a concern. I would like not to cut into the cable, but I will if I have to.
Would I be able to pick up the signal just by, for instance, having a wire crossing or coiling around the coax? Or do I need to cut in to the core and touch it? Would It be enough to strip off some shielding?
I will be doing my own experiments tomorrow. But I would love some insight from someone who has done something like this before. I would save a ton of hours and hassle if I could just cut and terminate the cables at the new location.
Thank you for your attention:)
