Floodlight Cam Mounting

I called Ring Tech support and the representatice could not find answers to my two questions in her computer data banks! 1. It appears that the Floodlight Cam MUST be installed on a wall that is PERPENDICULAR to the ground. I'd like to installl it to the junction box built into the soffit space under my roof which, of course, is PARALLEL to the ground (see attached image). All the homes in my neighborhod have existing security lights installed at junction boxes located in the roof soffits, not up against the walls of their houses. (Maybe that is how they were all designed when my neighborhood was constructed 25 years ago?!) It would seem an "easy" thing to be able to design and sell an adaptor for soffit space junction boxes that would then allow the Floodlight Cam to "hang down" from the junction box "as if" it were being installed on a wall junction box - maybe with an attachment that would allow two /Floodlight Cams to be installed back-to-back so that both directions could be covered when installing them in this way...and then it would be perfectly useable as designed (as it would be installed perpendicular to the ground by hanging down from the connecting piece that would attach to the junction box). As it stands, I can't use your Floodlight Cam on my dwelling as I do not have wall junction boxes! Can you help me out??? 2. Concerning your Indoor Cam. There is apparently no way to place this device high up near the ceiling in the 90-degree corner of a room - IF I want to affix it to a wall. So if I still want to do so - without requiring the construction of a shelf and then placing the Indoor Cam on the shelf in the 90-degree corner space - if I affix it to one of the two walls in a corner, can the camera then be rotated right (or left) to be able to effectively see the whole room as if it were sitting on a sheld and pointed out at a 45-degree angle in the 90-degree corner? I see in the manual that the Indoor Cam can rotate up and down but there is nothing anywhere to tell me how much or even it it can be angled right or left...and disappointingly your telephone technical staff couldn't answer that question either!!! The courtesy of a reply - and/or help from the community - would be appreciated. Thank you!
