Verisure, my alarm company, have a system whereby the alarm sounds WITHIN the house, not externally as with other alarm companies, going up in volume progressively so its deafening.
They argue that external alarms are usually ignored as people think they have gone off by mistake.
So the gradually ramped up internal noise is to put psychological pressure on intruders who also know a physical presence is guaranteed (Verisure have a guard response).
