LRAD Acoustic Hailing Devices

In late 2014, the protests in Ferguson, MO prompted a Federal Judge to issue a temporary restraining order barring police from dispersing peaceful protestors using tear gas and other agents without first issuing clear and unambiguous warnings. This has prompted activists to push for similar measures in other cities.

LRAD Acoustic Hailing Devices Deliver Clear and Unambiguous Messages and Warnings

  • Safer alternative to tear gas and other dispersement agents if demonstrations turn violent
  • LRAD technology ensures every warning is unambiguously heard  and understood, even over crowd and background noise at distances from 50 feet up to 1.5 miles
