Can I hang Flood Light cameras upside down?

I just bought a couple of Flood Light cameras but am waiting for them to arrive. I have only ever seen the Flood Light cameras positioned on a wall and never attached under an overhang. I have to hang one under my overhang, that is where the existing spot light is located in the front of the house at the garage. I saw that the stickup cameras can can be flipped upside down and you can rotate the image in the software. Can the same thing be done with the Flood Light cameras? If not, can I rotate the lights and the camera to work upside down when mounted? Thanks Larry
