Good points, high.

I didn't finish by recommending the butt splices for power. Good call. And I don't find anything objectionable about an exposed RG59 splice. After asking recently if there are any good crimp splices, I concluded that the cost of them, plus the need to carry another SKU for the rare splice, made it better to just put on BNCs and connect them with a barrel. I also make a loop at the splice so there's no tension on the connectors. They're totally visible but secure.

Also, I just corrected this: I meant to say that it's hard enough to get RG59 into all the close connections on a DVR. It would be much worse with RG6; plus you'd most likely have to use an F connector, then an F to BNC splice, making the entire connection unwieldy.
