Hello. It is a drop down movie screen by Screen Innovations and the projector is at the opposite side of the pool

Thank you! What about the weather? I'm trying to built this in Florida and worry about the electrical with all the storms that we get.

Weather is always a problem in Florida, especially outdoor. I would highly recommend discussing your options with an experienced AV installer as the humidity alone will destroy the screen (delaminate the screen material from the backing) and electronics unless specifically designed for outdoor use. They won't have that problem in AZ.
