A quick CCTV question

[sparkythecat]

I've installed numerous cctv cameras in the past, but all the equipment I've previously used has run on 12v DC. I now want to install a camera which runs on 24v AC.

So, is it possible to run supply and signal to and from the camera through one multicore cable, or will the supply interfere with the video signal?.
I appreciate that I can't use use a common ground as one can with a DC supply, but other than ensuring the video signal runs on a shielded cable core, what extra precautions do I need to take to ensure that the AC supply does not cause any interference?

Won't cause any problems at all in reality.

Think of all those video cameras up poles in commercial properties and in town. Granted, some of them are wireless but for the rest supply and signal necessarily up close and personal in the pole interior.

We use this type of cable when installing CCTV if it's any help to you. Has power cable bonded to the co-ax, so much easier and neater than running a separate power cable.

Be aware though to get the good quality stuff, some of the cheap shotgun is crap to say the least with very thin internal wires that basically make the stuff useless, so have a Google about

As Driller says 24V AC won't be a problem.
