Thanks for the tip... I saw the other solution, powered cat5...seems if you can access a common power source on each end, there would be a way to run a cable between the same locations, but possible outside where it would be ugly. Reminds me of looking down a row of apartments in Hong Kong...all of their utilities run on the outside walls...water, sewer, power, phone, etc...so they put their kitchen/bathroom on that same wall and then run power to the interior spaces.
Anyway, I am hoping I only need AC..seems that someone would have a CAT5 cable with an extra pair for DC power for the camera.
