Maritime Communication & Safety

Perimeter/Fixed Site Security & Response

LRAD-RX systems are being deployed around the world by maritime agencies for perimeter surveillance and security applications. Current 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 identifying, warning and deterring potential security threats from the safety of command and control centers, creating a fully operational unmanned perimeter security solution.

Using powerful, highly intelligible voice commands and deterrent tones to safely establish and enforce large standoff zones (up to 3 kilometers), LRAD-RX systems determine a security threat’s intent and provide maritime security officers 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 maritime 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 services around the world are experiencing increasing territorial water incursions and homeland security threats. LRAD’s attention commanding voice broadcasts and warning tones enable coastal defense personnel to unequivocally determine the intent of vessels not responding to radio calls and enforce marine and littoral regulations.

During suspect boat interceptions, LRAD systems ensure the Coast Guard’s commands and instructions are clearly heard and understood above engine, wind and background noise.

Colombia installed LRAD 300X systems on their coastal defense patrol boats to safely create large standoff zones and avert deadly confrontations when conducting interdictions at sea.

Through the use of powerful voice commands and warning tones, LRAD determines intent at distance and is an essential component in all EOF protocols. LRAD long-range communication systems have proven highly effective in anti-terrorism force protection, failure to heed situations and boarding operations by determining intent, safely creating large standoff zones around Coast Guard vessels, favorably resolving uncertain situations and saving lives on both sides of the Long Range Acoustic Device.

Naval Bases

The U.S. military employs LRAD-RX systems for perimeter security and enforcement of exclusion zones around certain naval bases including the Bahrain Naval Base pier.


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.

Maritime Facilities

LRAD-RX systems provide maritime facilities enhanced perimeter security to more effectively protect personnel and assets.

LRAD systems are in use in more than 70 countries around the world.
