Here is something that to me seems so obvious, but something that I have never seen or employed personnaly. Lets say for example I am designing a system for a high end jewelry store. I call for my glass breaks, my motions, a Potter vibration on the safe, high security contacts on the doors, and maybe a mat.. then I go home and the customer feels safe.
But for just another 175, the customer could buy a seperate panel just for the interior safe contact and the vibration detector. This way, if the intruder found his way into the store and bypassed the perimeter alarm, he would think he is home free.. But when he gets to the mother load, he is met by another independent syste. Of course, the panel would be installed away from the primary panel and a radio or cell could be used to transmit the signal.. My question is.. it's so obvious that it would be money well spent, why does no one do it??? Am I not seeing the big picture?
