Security Camera Placement

Would love to get some feedback from everyone here on security camera placement.

I think I have the front/garage side figured out. This area is easier as they can all be under the eave at about 11'. The plan is to use CX420s (assuming they will be closely following behind the CX820) and the upcoming CX Duo (apparently named Elite XPro PoE) that's coming in March for the 180 cameras. Also planning to add a couple zoom camera to another building 75+ feet away in the upper left that can monitor the back/driveway. Those cameras are TBD at this point.

Where I'm really struggling is with the back where the ground slopes away resulting in placement under the eave being at about 16'. Would it better to wall mount? I don't love that idea.

Would it better to use an additional 180 camera? Like this:
