So I'm installing a (16) camera surveillance system to cover my home and workshop. The system is a couple of packaged deals from Q-see via Costco. The cameras are their 1/3" Sony CCD, 43 mm lens, 520 resolution Color by day and B&W by night variety. The supplied cabling is siamesed RG59 with molded BNC connectors and a 2 wire low voltage line combined. The system comes with two - 110v A.C. in/(9) 12VDC out power inverter/distribution panels that allow some tweaking as to current to accommodate longer power line runs. My Install scheme is going to place (12) of the cameras close enough to the DVR that the supplied 60' cables will suffice, but the remaining (4) cameras will be mounted on my shop, thus requiring up to a 160' run between the DVR and the furthest away camera mounting.
Here's my concern. Landscaping constraints limit me to a single hand dug trench (quartz and clay devil dirt more typically associated with Hell's subsoils) that is a foot from a long chain link fence. The trench will have to carry a piece of 6 ga. 3 conductor w/ ground Direct Bury U.V. Romex my 60 amp power line), some sort of CAT 5 cable to carry the signal from my network router, and (4) video cables. My planned approach was to bury the 110 power line at the bottom (about 2' deep) cover with a little sand as a warning to future excavators, then a 1 1/2" PVC conduit a foot above - carrying the video cabling and the CAT 5.
Given the constraints of having all of the 12 volt power supplied by just two panels that are close to the DVR, I decided to power the (4) shop cams with short run dedicated wall warts and dump the siamesed RG59 for the long runs. This way I thought I could just run those cameras' video signals alone through something like RG6 or RG11 back to the DVR. My concern is interference from the 110VAC, CAT 5 FIOS feed, and the video signals all being so close together. What would be the best cable for the video, and what would be the best for the CAT5, that would assure no interference? I was looking for copper core - quad shielded RG6, but have no ideas beyond that. Also, I have the compression tool and BNC connectors to make up my own cables (as well as the CAT5) but wasn't sure which products to use, or even if my thinking on this is at all correct? I had also considered adding a layer of aluminum flashing between the buried Romex power line and the cable carrying conduit, but then thought that I might end up just creating some sort of crazy ground antenna.
Any help or suggestions would be greatly appreciated. Also I am intending to swap a couple of the cameras out for higher resolution units, just in case that would add anything to the criteria. The cables will have a minimum of turns to make and the tightest that I can envision is probably about a 12" radius.
I've also noticed that while "quad shielding" is usually easily discerned, the quality of the core is not always so readily apparent from some suppliers.
Any source suggestions for 250-1,000' spools would also be great. Been to Newegg, MonoPrice, Cencom and Blue Jeans Cable so far.
Last but not least, my shop is sealed with aluminum foil faced and backed iso foam board insulation on all six sides. I did such a good job that it is now my cone of silence, even though I didn't necessarily desire that effect. Now my cell phone and wireless home phone are useless once I enter the shop. I don't know if I should look at some kind of signal repeater, antenna, or possibly just running a separate phone line in the conduit with everything else.
Government "help" to business is just as disastrous as government persecution... the only way a government can be of service to national prosperity is by keeping its hands off.
