Just about finished with completely rebuilding the CCTV system where I work.
It was a royal mess!
Honeywell was the prime contractor, and did a beautiful job on the fire and intrusion alarms, but I think they farmed out the CCTV system to "Larry The Cable Guy"!
First, they were using RG-59 cable everywhere, which might be OK in your home (I won't touch the stuff!), but really shouldn't be used in a "Production Environment". It has a copper-plated center conductor, and if moisture is around (and it is in spades where this gear is located) the steel will start to rust, popping off the copper-plating. It's also not shielded very well, and this stuff looked like it was maybe 80~85% braid coverage, which means our signal can leak out, and other signals can leak in, degrading overall system performance.
Second, they used "twist-on" F-Type connectors and BNC connectors which start to degrade the minute you turn your back on them.
Third, even the crimped on connectors they used were of very poor quality, and some of them were rusted! ALL of them had been poorly crimped, in some case nearly crushing the coax. And the coax wasn't even properly stripped to install the crappy connectors. The outer jacket was split way back, the shield braid was hanging out, and the center conductor, which Type-F connectors use instead of a separate center pin in the connector, was way too long on some connectors, and barely long enough on others.
ALL the cable in this rack has now been replaced with Belden 7916A RG-6QS, which has a solid copper center conductor, two braid shields, and two foil shields. Connectors have all been replaced with Thomas & Betts (division sold to Belden) "Snap-N-Seal" outdoor-rated connectors, with O-Rings to keep them sealed.
BUT....the real downer to yesterday is that I sliced my left index finger with my knife while I was preparing a cable for the new connectors I was installing. No stitches were required, and I washed it out right away, but still, I try and be careful around sharp things.
Then 10 minutes later I jabbed my left thumb with my side cutters.....
OUCH! Yell, shout, and bled all over the place. Again, I went to the rest room, washed it out, dumped some H2O2 on it, and bandaged it up.
Now I've bandages on my left index finger and thumb. No sign of infection, but I never realized how much I used those two fingers.
And I'm still not finished with the equipment rack......
