security fencing

In the interest of keeping dogs in and people out...chain link offers strength, but can be climbed unless topped with barbed wire. Currugated metal offers privacy and is difficult to climb. I am attaching a pic of a security fence material that is hard to climb, and that seems pretty good.

Maybe a see-through security or chain link around the perimeter, then deeper in the yard, a fence that offers privacy, like currugated metal. These could be combined with tall hedges, etc.
Another consideration is whether or not to partially bury the fence.
