"Personal Alarm System: Volumetric alarm"

Personal alarm system

A volumetric alarm is a smart way to protect yourself and your loved ones.

Instead of electronics, this type of alarm system relies on a change in air pressure to warn you of any danger.

As soon as a door or window is opened, a 105 decibel alarm sounds... loud enough to warn you and scare off the criminal. This alarm is portable and perfect while traveling.
