Probably a naive question from a beginner but can I send the 12volt power supply through cat 5 as well as the video signal?

Will this affect the picture or (on a comparatively short run) is it better to use the coax with a separate power cable?

I know that baluns will be necessary with utp.

Its ok over a very short run but I would always recommend a seperate power cable

Not possible to fit the PSU local to the camera?

if its a long run, local supply. if less then 100m should be fine. as far as signal ect. but make sure your psu has enough ummph

Thanks for your replies guys.

It's about forty feet on an outside wall and there are apartments upstairs so psu can't really be local.
