Homeland Security

Reliable Emergency Communication

When major disasters strike, existing infrastructure is disrupted and compromised, power and communication systems fail, rural areas can be isolated and urban streets can become impassible and dangerous. Reliable communications for maintaining civil order, conducting search and rescue operations, and providing relief distribution becomes highly problematic for homeland security personnel.

LRAD life safety systems go anywhere communication is needed. From the portable LRAD 100X to larger systems temporarily or permanently mounted on vehicles, vessels, trailers or helicopters, LRAD systems are highly effective in communicating evacuation and shelter-in-place information over large areas before, during, and in the aftermath of disasters.

Unlike the limited voice quality and range of portable P.A. systems and bullhorns, LRAD broadcasts with exceptional intelligibility and vocal clarity over large distances (from close range up to 5.3 sq. kilometers) enabling communication over wind, traffic and background noise, even inside buildings and vehicles. Portable LRAD systems are self-contained and do not rely on external power or communication infrastructure.

LRAD broadcasts are safe and have been optimized to the primary human hearing range of 1 – 5 kHz. By maintaining a smooth frequency response with an intensity variation of less than 5dB, LRAD has eliminated the shortcomings of competitor systems by preventing audio fading and producing clear, unambiguous communication across all broadcast frequencies.

LRAD’s safe warning siren and highly intelligible voice broadcasts keep homeland security personnel, emergency responders and civilians out of harm’s way during localized or wide area disasters.
