Is the power supply a listed Class 2 power supply?

Re: SECURITY CAMERAS
Yes, you can cerainly do that. More commonly, we'd use "siamese cable", which is designed for that purpose. It is an RG59 or RG6 with a red and black stranded conductor molded in the same jacket as the RG59.

Re: SECURITY CAMERAS
Bob Are you sure it is "AC" and not "DC" because we did some that we used a source coupler to piggy back the supply voltage right on to the coax, and then seperate them when you get to the camera, But they were 24 volt DC cameras.
Just a thought.

I think 820.52(A)(1)(b) (NEC 2002) would make it a violation.

Re: SECURITY CAMERAS
Ron that is if the power supply is a class 1 or regular branch circuit power, Most of these cameras use a class 2 power supply and are allowed to be in the same conduit and or even use the same conductors to ferry the power to the cameras, look at 822.52(A)(1)(a). Now if there is a 120 volt heater circuit to the camera then that has to be kept separate.

Re: SECURITY CAMERAS
Hurk,
I will guess that is class 1 (maybe 2).

Hurk,
From Bobo's response, it sounds like it is a wall wart plugged into a receptacle.

Most security cameras run off of 24v AC. Or atleast all the ones I have run into (quite a few of various age and manufacture).
