My Aunt had every door and window in their house and garage wired -silent alarm to local PD and the most deafening sirens that went off at the house suppose to be burglar proof.They were only gone 90min.The house was nearly empty and they even took the full size van and flat trailer all while the sirens were blaring and before PD showed up. If they want in they will get in.The officers told them to save their money and keep their insurance paid and the best defense is a nosy neighbor.
