Hello, Is it an NEC violation to have video cabling, and also the power wiring for the cameras only, in the same 2" PVC conduit? If a certain type of low voltage cable needs to be used, what kind does it need to be to be up to code? Is this in the NEC? Thanks. :)

The signal feed cabling will be determined by the camera itself, most being coaxial with some newer market items utilizing Cat-5e.

In a perfect word, I would avoid having the power supplying line in the same conduit as the signal feeds as it will almost certainly bleed interference. Even 5-12v of current can cause interference when run parallel over 10+ feet next to the signal cable.

As for NEC articles, I don't have a reference handy to lookup any specifics.
