Large Event Communication & Security
Law enforcement agencies tasked with keeping large outdoor events secure and peaceful face unique challenges.
The limited broadcast range and poor voice quality inherent in bullhorns and portable P.A. systems place police officers in close proximity to large crowds and force them to repeat messages and instructions numerous times. Many officers are usually needed to secure events, handle incidents, calm crowds, clear roads, and open and close venues.
LRAD systems address these challenges by providing event security personnel with a communications capability that is portable, rugged, easy to use, cost effective, and fills multiple needs. LRAD systems broadcast highly intelligible voice messages and alert tones from close range up to 2 kilometers. Multilingual voice communications are clearly heard and understood over crowd, event and traffic noise, even inside vehicles.
LRAD broadcasts are safe and have been optimized to the primary human hearing range of 1 – 5 kHz range. 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 serves as a force multiplier when a limited number of officers are available to secure events including:
- Sporting Events
- Outdoor Concerts
With its commanding alert tone to safely ensure attention to the exceptionally clear notifications and instructions that follow, LRAD systems provide public safety personnel ONE VOICE® to communicate to crowds at large events.
Law enforcement and public safety agencies around the world, including over 250 U.S. cities, counties and states, use LRAD systems and support equipment.
