Safeguarding the Public & Protecting Officers

Increasing demands on law enforcement agencies have stretched resources to the limit and the tools they use must be portable, rugged, easy to use, cost effective, and fill multiple needs. LRAD fills the critical gap between the poor voice quality and limited broadcast range inherent in bullhorns and vehicle P.A. systems, and kinetic measures including water cannons, tear gas projectiles, rubber bullets, pepper balls, Tasers, and flash bang grenades.

LRAD is not a weapon; LRAD is a highly intelligible, long range communication system and a safer alternative to kinetic force.

LRAD systems safely broadcast highly intelligible messages, warnings, notifications, instructions and commands from close range up to 3 kilometers to individuals or large crowds in a wide variety of law enforcement situations.

As part of field and special response team operations, LRAD safely extends the perimeter in friendly or escalated environments keeping the public and officers out of harms way. Law enforcement agencies are also using LRAD to:



LRAD’s optimized driver and waveguide technology ensures every broadcast cuts through wind, engine and background noise and is clearly heard and understood, even inside vehicles and buildings. Through the use of live or recorded multilingual voice messages and alert tones, LRAD systems establish large safety zones, unequivo­cally determine intent, favorably resolve uncertain situations and save lives on both sides of the Long Range Acoustic Device.

Law enforcement and public safety agencies around the world, including over 250 U.S. cities, counties and states, use LRAD systems and support equipment.

Proven Performance

Marine / Port Patrol

CA, Sacramento PD, Marine Unit

The Sacramento Police Department’s Marine Unit uses an LRAD 300X system mounted on their jet boat to conduct daily water operations. LRAD’s safe alert tone is used to command boaters’ attention, followed by highly intelligible instructions and directions such as “Cut power”, “You are entering a restricted area”, and “Turn your boat around.”

“The LRAD has proven to be a tremendous asset. On a daily basis we use the alert tone to gain the attention of motorists and boaters. It’s a unique device that projects sound more powerfully and more precisely than previous P.A. systems. We use LRAD’s microphone to give boaters instructions and directions. We also frequently use LRAD’s MP3 player to pre-record and playback common instructions and commands at the push of a button. This frees our attention to focus on what boaters are doing.” – Sacramento PD

SWAT Operations

TX, Austin PD SWAT

“Since receiving the LRAD 300X, the SWAT team has employed it on several occasions and have been completely satisfied with its performance and capabilities. It is the ideal communications platform during SWAT tactical operations.

As the project manager for the LRAD purchase, I have been extremely satisfied with the support I have received from you and your company. I would highly recommend this product or other models of this product from LRAD to other law enforcement agencies.” – Lt. David Mahoney, Austin, TX SWAT

CA, Santa Ana SWAT Team


The Santa Ana SWAT team used an LRAD system to drive gang members from a house.

When they arrived at the scene, officers suspected three or four gang members were inside. But after employing LRAD, 10 suspects peacefully emerged, enabling the SWAT team to safely conduct their operation without having to evacuate neighboring homes or enter the house by force.

Large Crowd Communications

MI, Detroit PD, International Freedom Festival
At Detroit’s International Freedom Festival, local law enforcement and security personnel utilized several LRADs as P.A. systems and to keep the peace. The LRAD systems broadcast messages welcoming visitors and provided public announcements throughout the event. As large crowds formed and grew restless near the end of the festival, the LRAD systems were used to help prevent incidents of crowd violence.

MD, Salisbury PD


When large student block parties get out of control, Salisbury, MD police use LRAD 500X systems to safely disperse crowds and restore order.

SC, Columbia PD


During large crowd celebrations, the Columbia PD use LRAD 100X systems magnetically mounted on their patrol cars to inform revelers it’s time to go home. Fans that linger are warned that they may be subject to arrest. Crowds usually disperse quickly resulting in fewer incidents and arrests.

MA, Boston Police Department


The Boston Police Department employed LRAD in Kenmore Square during the 2005 Super Bowl celebration in place of kinetic measures after the death of Victoria Snelgrove in 2004.

Officers fired FN303 rounds in an attempt to control the wild Red Sox 2004 ALCS championship celebrations. One round hit Ms. Snelgrove in the eye socket and lodged in her brain.

Civil Unrest & Riots

Ferguson, MO

LRAD systems were used by local and county law enforcement to communicate to and disband large protests during the civil unrest that lasted for several days.

“You had a large concentration of people out here on the street…Once the LRAD sounded, a couple of warnings from the loudspeaker, the people scattered all at once…particularly once the LRAD went off. I was surprised to see just how effective that was.” – Reporter Mike Tobin

NY, New York Police Department


The New York Police Department has used LRAD for crowd communications and control during the Republican National Convention protests in 2004, the Occupy Wall Street protests in 2011, the Black Friday and Eric Garner protests in 2014, and at certain Times Square New Year’s Eve celebrations.

G20 Summit Protests, Pittsburgh PD


The Pittsburgh Police Department used several LRAD systems to communicate to unruly crowds and disperse unlawful protests during the September 2009 G20 Summit
Nate Harper, the Pittsburgh police bureau chief, told reporters. “It served its purpose well.”
Raymond DeMichiei, Pittsburgh’s deputy director of emergency management and homeland security, stated the devices worked well without hurting anyone. “Every police officer I talked to thought it worked famously,” said Mr. DeMichiei, who ordered the devices for Pittsburgh. “The bottom line is we could maintain order with the protesters without hurting them. It makes them uncomfortable but does not hurt them,” he said, noting that Pittsburgh police had been trained to use the devices properly.
Pittsburgh PD officers also use LRAD systems for a variety of situations including peacefully ending barricaded subject situations.

Singapore


More than 1,000 foreign workers were stranded in buses during a traffic jam that lasted several hours. An LRAD 100X was used to explain the situation to the frustrated workers in several different languages, calming and defusing a potentially volatile situation.

Emergency PA & SAR

WA, Seattle Police Department

The Seattle Police Department deployed an LRAD 1000 to safely talk down a man threatening to jump from a downtown pedestrian bridge. After 14 hours of trying several tactics without success, commanders at the scene decided to move all their officers away from the man’s line of sight and use LRAD
“Within two to three minutes after beginning to tell the subject to remove himself from the roof, he complied. He voluntarily used the ladder which had been provided early in the incident and he was subsequently placed into custody without incident.” – Capt. Steve Brown

CA, San Diego County Sheriff’s Department


San Diego County Sheriff’s Department purchased an LRAD system through Homeland Security Grant funds under LETPP. It is maintained by the Emergency Planning Detail and primarily used by the Search and Rescue (SAR) Unit.
The LRAD system is used to issue safety advisories, warnings, and other emergency-related notifications and is recognized as a valuable tool for broadcasting announcements to specific locations without disturbing adjacent areas. The system is also deployed by SAR to call out to lost or missing persons in the canyons and hills of rural San Diego County

Active Shooter / Armed Gunman

The ERT confronted an armed gunman in a vehicle located approximately 100 meters from their position. ERT officers attempted to communicate with the gunman by shouting, but to no avail and the armed suspect opened fire. After exchanging gunfire, officers believed the gunman was wounded. However, since he had multiple high-powered weapons and had been returning fire, getting closer was not an option.

Officers used their LRAD 100X system to broadcast clear voice messages ordering the gunman to discard his weapons and come out of the vehicle. The gunman peacefully complied.

Elevated Risk Operations

Protests, riots, SWAT operations, drugs and firearms arrests, hostage and barricaded subject situations, serving warrants and eviction notices, and other high risk duties often put law enforcement officers, suspects and bystanders in harms way.

The limited broadcast range and poor voice quality inherent in bullhorns and vehicle P.A. systems put officers in close proximity to hazardous situations. Building walls and background noise often impede delivering clearly understood notifications, warnings and instructions. When officers disperse violent crowds, knock on doors or enter structures concealing dangerous perpetrators, the threat of injuries and fatalities greatly increases for officers, suspects and the public.

LRAD systems provide SWAT teams, U.S. Marshalls, DEA and ATF agents and other law enforcement personnel an essential long-range communications capability deployable on the ground and in the air.

LRAD systems broadcast focused, highly intelligible voice messages and warning tones from close range up to 3 kilometers. LRAD’s optimized driver and waveguide technology ensures every broadcast cuts through wind, engine and background noise and is clearly heard and understood, even inside buildings and vehicles.

LRAD systems are rugged, portable, easy to operate and can be temporarily or permanently mounted on cars, armored vehicles and helicopters. LRAD is a force multiplier when a limited number of officers are available to respond to elevated risk operations.

Through the use of powerful voice broadcasts and warning tones, LRAD establishes large safety zones, determines intent at safe distances, resolves uncertain situations and saves lives on both sides of the Long Range Acoustic Device.

Law enforcement and public safety agencies around the world, including over 250 U.S. cities, counties and states, use LRAD systems and support equipment.

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:



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.

Campus Security

Frenzied students and fans stampeding at a football stadium following a hard fought game…Thousands of angry students protesting and rioting…Active shooters terrorizing business and school campuses…These and other dangerous situations pose significant challenges for campus security and law enforcement to keep students, staff and faculty safe and out of harms way.

LRAD provides campus security and law enforcement a safe, highly effective communications capability. Broadcasting crystal clear live announcements and recorded messages, LRAD systems assist campus security and law enforcement officers communicate to students, staff and faculty before, during and after large events and crisis situations. LRAD broadcasts can be clearly heard and understood in and around an incident area or throughout a large campus, even inside buildings and vehicles.

LRAD systems are up to 10X louder than bullhorns and vehicle P.A. systems and considerably more intelligible at any range. Self-contained and self-powered, LRAD replaces ineffective bullhorns and less effective reverse 911 calls to ensure students, staff and employees hear and understand instructions simultaneously during an emergency.

When local infrastructure fails, LRAD serves as a primary or back up mass communication system to broadcast warnings and instructions campus wide during emergency situations including bomb and security threats, building lockdowns, CBRN and HAZMAT incidents, impending severe weather and other potentially catastrophic events.

Clearly heard and understood above crowd and traffic noise, LRAD’s voice broadcasts and alarm tone are safe and easily modulated. LRAD is the safer alternative to water cannons, tear gas projectiles, rubber bullets, pepper balls, Tasers, flash bang grenades and other kinetic measures. LRAD also serves as a force multiplier when a limited number of campus/law enforcement personnel are available for crowd control at planned or spontaneous events.

LRAD systems communicate warnings and notifications in a variety of campus security situations:
