i use my 2nd gen indoor nest cam in a window to look outside. this cam housing raises the camera about 25mm to get above the window frame while also hiding the fact that its a camera and cover the status light. making the housing black will work best for concealment. from the street it simply looks like a black box.

simply change the tilt of your camera and then drop it in the housing. you may need to rotate the housing with the camera in it but the large opening in the back for the wire will not provide any restrictions.
