I was thinking of the alternative solution, put the battery at the camera end that you lower down. I presume there will be a rope to take the weight off the ethernet cable, why POE when you don't need to?If you decide to power the camera from 12V, check the range of voltage which is allowed. If it is, say, anything between 11-14V d.c. (at least), then you should be able to power it direct from the battery. Otherwise you will need to regulate the supply.Also any idea on how to power the camera 12V conector from the Pi? I have external 12V 7Ah battery.
Given the length of cable, I'd recommend 'proper' POE. That uses around 50V on the cable, so the current drain, and therefore the voltage drop, will be about a quarter of that using 12V.
