I whipped up some aluminum mounts for 360 security cameras, for mounting on the corners of our metal building. I had some scrap 0.90 aluminum sheet, so I used the brake and band saw to create some mounts.
The top support curve was actually a left over scrap from a race car splitter, which I trimmed to fit. I TIG welded the aluminum together and spray painted.
The camera is spaced off the building to give it a view down the sides.
