Check out "Burglar Bombs".
These are a 6oz canister of pepper spray which literally "fumigate" the area in which they are activated. These in conjunction with an incredibly loud alarm Inside the facility and Out, and an auto dialer alarm, I'm hoping will work for my new start-up. I've been told by a friend who has a burglar bomb that the "escapee" did not make it very far before he was caught with his truck wrapped around a tree within a 1/4 mile of the break-in. He simply could not see to drive. These bombs do dissipate in an hour or so, but the other alarm systems should have brought you to the shop by then. I need to add that nothing was lost in this example break-in, other than damage to the door. My two dogs are always there, too.
