Can I run 24V AC 60W over CAT6 24AWG spare cores?

Hey,

I have run about 50m of CAT6A 24AWG, and run this underground to a pole. I have a HikVision Speed Dome which takes a 24VAC 60W, unfortunately it doesn't take POE (which I thought it would)

The camera is going to be mounted on a pole, but unfortunately the workmen who put up the pole managed to get cement down the underground conduit, so I would rather not re-run the power.

What I was thinking of doing was using the orange and green pairs on the CAT6 cable only (Pins 123,6), and keeping either the browns or the blues free from the RJ45 plug to run the 24VAC.

I could put the power into the CAT6 at about 20 metres (The distance it runs underground to the building).

So the questions are:

1. can I do this without too much degradation in signal?

2. I know that POE is DC so wonder if the Cosine Wave generated by AC power would add additional interference

3. if 1 & 2 are ok would you go with running the power over the entire 50m (easier as the power already in the Data Cabinet) or running from the 20m (where I have to run a power outlet to)

Thanks,

Lloyd

From some quick searches for cable sizes and ratings, I think you are going to struggle to use that cable for that duty.
Even at the shorter 20m distance you'll see a significant voltage drop for 60Watts / 2Amps+ through 24 AWG (0.2mm sq.).
Kind of 24V AC in at 20m distance but less than 20 volts presented at the camera, and likely a very warm cable too

I feared as much, thanks for the speedy reply Phil!
