Spotlight cam wiring & power specs?

I'm interested in a few Spotlight cameras for my house. The home once had CCTV type cameras that were wired from the outside location back to an interior closet with power. The cables are "siamese cables" which is essentially a coax + 2 small gauge wires that carried the low voltage DC power from the power adapter in the closet to the cameras. Does the Ring Spotlight camera send DC voltage from the plug to the camera? If not what are the electrical specs and required wire size? I'd like to use my existing small gauge wires to power the camera but I need to know the power specs & load. Said differently, does Ring have any cameras that are compatible or could be made functional with POE?
