Perimeter Security & First Response

LRAD-RX systems are being deployed by homeland agencies throughout the world for perimeter security and surveillance applications. Current security and surveillance 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 ranging from close range up to 3 kilometers, LRAD-RX systems determine the intent of a security threat 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.

LRAD-RX Systems
  • Establish larger security areas for increased asset protection
  • Provide greater coverage with fewer personnel
  • Determine intent from extended distances
  • Extend perimeter security and enforce exclusion zones
  • Reduce false alarms and protect security personnel

Coast Guard

Coast Guard agencies are experiencing increasing territorial water incursions and homeland security threats. LRAD’s attention commanding voice broadcasts and warning tones enable coastal defense personnel to determine the intent of vessels not responding to radio calls and assist local marine officers enforce waterway regulations.

Colombia utilizes LRAD 300X systems on their coastal defense patrol boats during interdictions at sea. LRAD ensures the commands and instructions broadcast from Colombian maritime security vessels are clearly heard and understood above engine, wind and background noise to safely create large standoff zones and avert deadly confrontations.


LRAD-RX systems have proven effective in steering bird flocks away from runways where aircraft are most vulnerable to potentially disastrous bird strikes. LRAD broadcasts a wide variety of tones and predator calls to move birds away from airports and can significantly reduce the approximately $1.2 billion spent each year in aircraft and facilities bird strike damage repairs.

The airport in Bologna, Italy has successfully used LRAD systems since 2010 to substantially reduce bird strikes, protect passengers and aircraft, and preserve wildlife.

LRAD-RX systems also remotely establish and enforce security perimeters around airports to prevent trespassing and unauthorized vehicle incursions.

Power Plants & LNG Facilities

Nuclear power plants and liquid natural gas processing facilities are deploying LRAD-RX systems to protect from unauthorized perimeter incursions and waterside approaches.


The Ports of Corpus Christi, Texas and 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.

Government Facilities

Tower-mounted LRAD-RX systems provide enhanced government facility perimeter security to more effectively protect personnel and assets.


LRAD-RX systems safely warn boaters and fishermen who get too close to dams or enter other restricted areas. LRAD also broadcasts wide area warnings of approaching storms and facility closures.

Water Treatment Plants

Large water treatment facilities are upgrading their perimeter security with LRAD-RX system integrations. The LRAD-RX enables plant operators to remotely respond to potential incursions.
