Remotely Operated Acoustic Hailing Device

Remotely Operated Acoustic Hailing Device

The customizable Remotely Operated Acoustic Hailing Device, also known as Long Range Acoustic Device LRAD, with a pan and tilt positioning device, is an ideal sound reinforcement solution for remote locations. With 156 dB of forceful acoustics, operators have the ability to issue clear, authoritative verbal commands and cut through high background noise environments (such as airplanes, helicopters, sirens, vehicles, and boisterous crowds) to ensure unmistakable commands. Piercing alert tones are heard loudly and clearly.
A powerful built-in alert tone projects an attention-getting, high frequency warning which enhances military and security personnel’s response. This non-lethal deterrent tone can be as loud as 156 dB and is highly irritating. It can be compared to a water cannon, but with sound.
Operated remotely across an IP network, the Remotely Operated Acoustic Hailing Device allows operators to respond to potential threats from a safe setting, creating a complete unmanned perimeter security solution.
Enhancing remote security, the Remotely Operated Acoustic Hailing Device equipment bay is easily configured with an optional video camera, search light or laser dazzler. The addition of IP-enabled sensors gives security personnel additional time and valuable information to evaluate a potential threat.
With an acoustic footprint of 2000 meters and a narrow acoustic beam of +/-5°, clear, intelligible and authoritative commands are broadcast to intended targets with industry leading clarity.

The technology behind the Acoustic Hailing Device (Long Range Acoustic Device LRAD) was developed to support the protection and exclusion zones around U.S. Navy warships following the October 12, 2000 small-boat terrorist attack on the USS Cole off the coast of Yemen killing 17 sailors and causing $240 million in structural damage to the $1 billion ship. Acoustic Hailing Devices are currently used around the world on sea (military, private and commercial vessels), on ground (tanks, armored vehicles, military/police vehicles, structures), and in the air (helicopters).
