Adjustable Angle Bracket

I made this bracket to mount a CCTV camera on an internal wall of a window, Drill and screw 4 holes for M5 bolts / screws, add a M5 Csk Head bolt and nut and then fit the adjustable bracket, i do have an optional plate to fit to this but it is specific to my CCTC camera, can design and upload any configurations if requested.
