Recommended Way To Wall-Mount A Bullet On A Vinyl-Sided Exterior Wall?

[Dramus]

I'm inexplicably fascinated by this new Dahua PTZ1C203UE-GN,

currently being discussed in New Dahua Bullet PTZ - PTZ1C203UE-GN

Question: What is the best/recommended way to wall-mount such a thing on a vinyl-sided exterior wall? Something like this, perhaps?
