I have a PVC2300 mounted on the second floor of a building at a difficult to reach site. The camera is reliant upon PoE for power, as there are no other power options in the area. I am trying to resolve an issue with excessive sunlight that distorts the image at specific times of day and am wondering if a lens upgrade might be able to help mitigate some of the image distortion we are seeing under bright sunlight conditions. Spefically, I am considering an auto iris lens. I can't find an authoritative answer, but was wondering if such a lens would be able to be powered directly from the camera or whether I would need to provide a secondary power source.
