Camera placement

Ok sounds good.

See attached, I do have that PFB203W mount as well.

Now for mounting onto the vinyl siding. Any links or tips on doing this? See attached as well for what is behind each wall. I would like to finish this today.

FYI - some have custom 3d printed vinyl siding mounts for cameras.
 
Sorry no experience with such.
I did mount one to metal siding and just used long self tapping screws to get into the wood
