Long Range Acoustic Device

(Акустическое устройство дальнего действия)

The Long Range Acoustic Device (LRAD™) is a breakthrough long-range hailing and warning device designed to communicate with authority, affect behavior and determine intent. It has the unique ability of providing amazing voice and tone clarity in a narrow beam at distances over 300 meters using only two amps of power. In addition to microphone input, LRAD™ can communicate in various languages via the built in MP3 player or Phraselator™.

As a method for safely addressing the difficult missions of waterside force protection against small boats, crowd control, area denial of personnel, clearing buildings and visit board search and seizure operations, LRAD™ puts distance between a potential threat and our troops to save lives on both sides of the device. LRAD™  can also be configured to provide live, continuously recorded video and audio from a remotely controlled ruggedized pan, tilt and zoom mount for high value infrastructure “first responder” capability.

LRAD exceeds the CINCLANTFLT Naval Vessel Protection Zone for stand off distances for ships pier-side, at anchor or in restricted waters.
