I access 18 different Hydro One transformer sites, and the security that they put into those sites is crazy (due to the high amount of copper on-site) to prevent people from trying to get in! Some sites have a razor-wire inner fence with barbed wire on top and conventional fencing on the outside. The fences also extend into the ground by 6 inches and then out under the ground another 2 feet.
Inside the sites, there are electric fences.
Finally, there are remote sensors on most copper samples in these sites so that they can be tracked if stolen. This says a lot for how much copper is worth (currently US$ 2.8393/lb)
