Mount camera below eave; vertical field of view

I need to mount my floodlight camera on a new outlet box to be installed on my single-level home, just below the eave and rain gutter. I want to mount it as high as possible (around 8'), but I would prefer to not have the eave or gutter always showing. Is that a problem? Is the camera's vertical field of view the same as the horizontal field of view, 140 degrees? Thanks in advance for any help you can provide.
