Can i install the camera upside down? ie: cable on the top.. instead of the cable coming from the bottom?

The Nest Cam Outdoor does have the ability to rotate the image 180 degrees within the Nest app, so you can install these upside down and be able to reverse the image allowing you to see everything right side up.
