I felt by the time you used all of that, the PTZ wasn't that mini and would be better off with a standard PTZ, so I used an angle bar that allowed the bracket to have a minimal footprint not even seen and tucked it up close to the house as well.
The Everbilt 8 in. Corner Brace is ideal for reinforcing inside of right-angle corner joints. Countersunk design allows screws to sit flush with material. Easy to install.
