RL811A night vision "blind spot". Recently installed 2 811A on each side of drive way. Daytime images/video is great. Night time reveals an IR blind spot (at least I think that is what it is). The picture shows the "problem":
Both images show a blurry spot, horizontally centered and vertically somewhen above the center. Both cameras show a virtually identical problem. I think it is because the lens enclosure has a raised edge and blocks light from the IR LEDs. In particular light directed towards the center would hit the "rim" of the lens enclosure. I have throughly cleaned lenses and inspected them for moisture inside. They are very clean, and no moisture.

I am inclined to believe this is a design defect, but would be pleased to hear it is something else, fixable.
