How about enough lights, buzzers, and sirens that a theif would not want to take the chance the intrusion event isn't being transmitted to the authoroties. And/or hidden cameras. That wouldn't prevent intrusion, but might give you a good chance to deal with it later. The first incident could significantly deter subsequent ones. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
