Sorry, yes I mixed up the cameras. You're correct, the G3 Flex cameras are fine, I was thinking about the G4 dome cameras that had some IR issues. I think they were cleared up with the angling of the lens covers though.
Yes when I mention 'panel', I'm talking about the electrical panel cover that can be removed with the 2 screws.
I think I have a new idea for the G4 bullet camera. I can remove the metal panel cover, then buy this Box, use the top only, which has a larger in surface area than the electrical cover, drill 2 holes so that it can attach to where the panel cover used to be, and then drill 2 holes to the top of the plastic cover to attach the G4 Camera. I'd have to paint the cover to be the same color as the house, but I think it should work..
