Ring Floodlight Cam Wired Pro - installation question - height

I am looking to purchase the Ring Floodlight Cam wired Pro but have a question that I need answered before making the purchase. I am looking to install this product at a height of 20 feet and want to understand if the product will function at that height. I realize the recommended height is 9' for optimal performance but that is not an option. The installation location is shown below. The sensor and camera will be pointed down at a 20-degree angle. Does the community have any thoughts on this, recommendations, guidance, etc. ? Thank you.
