Homeland Security

Communicate Anytime, Anywhere


Security measures that enhance public safety and help secure critical infrastructure are top priorities in today’s escalated threat environment. In any operational scenario, the products and systems that homeland security agencies use must be versatile, rugged, easy to operate and cost effective. The Long Range Acoustic Device is a groundbreaking long-range communication system used to broadcast critical information, instructions and warnings from close range up to 3 kilometers.

LRAD turns passive surveillance systems into first responders by broadcasting warning tones and highly intelligible voice messages to potential threats. LRAD systems safely determine and alter threat intent, eliminate false alarms, reduc­e manpower, and create a permanent perimeter presence around airports, seaports, nuclear power plants and other critical facilities.

By safely creating and enforcing large standoff zones from extended ranges, LRAD protects vital infrastructure and also provides Homeland Security agencies an essential communications capability during regional or national emergencies.

The Ports of Corpus Christi, Texas, Ras Laffan, Qatar and Aqaba, Jordan installed advanced security systems featuring the LRAD-RX to broadcast multilingual hails and warnings to inbound ships not responding to radio calls. The LRAD-RX reduces false alarms and port security response times associated with confirming or denying port entry.

Critical Infrastructure

Securing Critical Infrastructure

Throughout the world, LRAD-RX systems are enhancing security at power plants, dams, embassies, government facilities, water treatment plants and other critical infrastructure. Most systems with cameras, thermal imaging, motion detectors and other sensors only watch.

The remotely operated LRAD-RX provides the vital ‘first response’ capability missing from observe-only integrated security systems. Operating across an IP network, the LRAD-RX turns passive surveillance systems into remote first responders by creating a fully operational unmanned perimeter security solution that identifies, warns and deters potential security threats from the safety of command and control centers.

Using powerful voice commands and deterrent tones to safely establish and enforce large standoff zones from close range up to 3 kilometers, LRAD-RX systems determine a security threat’s intent and provide security personnel more time to initiate an elevated response to unauthorized incursions if necessary.

Featuring an integrated zoom camera, high intensity searchlight and an IP-addressable full pan and tilt drive for precise tracking and targeting, the LRAD-RX can also be integrated with radar to provide automated intruder alerts. By turning passive surveillance systems and command and control centers into remote first responders, the LRAD-RX provides a permanent perimeter presence, reduces false alarms and protects homeland security personnel from potentially deadly situations.

Evacuation & Shelter Notification

When major disasters strike, existing infrastructure is disrupted and compromised, power and communication systems fail, rural areas can be isolated and urban streets can become impassible and dangerous. Maintaining order and safely conducting evacuation efforts becomes highly problematic for homeland security personnel.

Unlike the limited voice quality and range of current emergency warning systems and bullhorns, LRAD broadcasts with exceptional intelligibility and vocal clarity over large distances (from close range up to 5.3 sq. kilometers) enabling homeland security personnel to communicate above wind, engine and background noise, even inside buildings and vehicles. Portable LRAD systems are self-contained and do not rely on external power or communication infrastructure.

LRAD goes anywhere communication is needed. From the portable LRAD 100X to larger systems temporarily or permanently mounted on vehicles, vessels, trailers or helicopters, LRAD systems are highly effective in communicating warnings, instructions and commands over local or large areas before, during, and in the aftermath of emergency situations.

LRAD systems free homeland security personnel from having to go door-to-door, neighborhood-by-neighborhood to inform citizens of evacuation or shelter-in-place instructions.

Broadcasting safe evacuation routes and protocols, identifying hazardous egress routes and other dangers, and communicating wide area updates on changes in evacuation or shelter-in-place instructions, LRAD broadcasts facilitate safety during disasters and save lives.
