Genasys’ LRAD – Long Range Acoustic Device – a super-specialized speaker optimized for sending warning tones and verbal messages over long distances so everyone can hear and understand voice clearly. The town of Mill Valley California upgraded all five of its air raid sirens to (LRADs) with satellite (connectivity) and battery backup. For less than the price of one fire truck, they can tell people how to survive.
