From the picture Mario posted I'd say you do some incredible work! But this is a small-ish church. They want to be sure that they use quality cabling but for in-wall can a standard RG6, 3ghz, solid copper core coax work? 10 cents a foot vs a dollar a foot?

Their video guy has also been researching and thinks they need a stranded core cable (in the walls). Is that true? (From the wall to the cameras would be factory whips)

I just don't want them to pay for wire they don't need if that money can go to other equipment.

Thanks!
