Mounting in Engineered Wood Soffit?

Has anyone ever mounted a bullet cam to an engineered wood soffit like LP SmartSide? This is the material used for both trim and soffits at my home. I have a bullet camera with a Dahua aluminum junction box ready to go, but I can't decide if I should try to mount it to the soffit or mount it to the side of the house just below the soffit.

Thanks in advance for the help.
