Get the message out - Strong, Loud and Clear with LRAD-RX


The LRAD-RX™ enables system operators to detect and communicate with an intruder over long distances. Featuring an integrated camera, high-intensity searchlight and IP-addressable full pan and tilt drive for precise aiming and tracking, the LRAD-RX™ can also be integrated with radar to provide automated intruder alerts. With its automated capabilities, it reduces manpower and false alarms while providing a highly efficient, cost-effective security solution. LRAD-RX™ uses its directionality and focused acoustic output to clearly transmit critical information, instructions and warnings beyond 3,000 metres. Through the use of powerful voice commands and deterrent tones, large safety zones can be created while determining the intent and influencing the behaviour of an intruder.


The LRAD-RX™ can be operated remotely across an IP network enabling system operators to respond to potential threats from a safe location while creating a complete unmanned perimeter security solution. It accepts intruder position information from other IP-enabled sensor systems to find and track potential threats automatically. The LRAD-RX™ provides a large safety zone to give security personnel additional time and valuable information if an elevated intruder response becomes necessary.


The LRAD-RX™ features an emitter head, integrated camera, high-intensity searchlight (optional) and LRAD® Corporation’s own robust full pan and tilt capability for precise aiming and tracking. Audio output from the LRAD-RX™ is highly directional so nearby personnel and system operators are not exposed to excessive audio levels, while still providing exceptional voice intelligibility and tonal clarity over long distances.

  • Longer stand-off distances for increased asset protection
  • Larger coverage with fewer personnel
  • Determination of intent of groups or individuals from extended distances
  • Maritime vessels can clearly and forcefully communicate with small vessel threats
  • Perimeter/infrastructure protection for oil and gas platforms, mining and chemical/power plants
  • Transmitting bird distress calls to repel targeted birds from crops, buildings and airports
  • Enforcement of safety zones for maritime vessels

Systems Integration & Surveillance Software
LRAD-RX™ can be integrated into a sensor network to locate and track a potential threat. This enables the command and control centre to respond to the threat from a safe remote location. The coordinates obtained from the sensors can be transmitted to the LRAD-RX™ for precise tracking. This gives security personnel additional time and valuable information if

an elevated intruder response becomes necessary. A full API is available for systems integrators.
The Graphic User Interface (GUI) provides a visual control interface for the user. This interface consists of a real-time video display and a graphical control interface for the LRAD-RX™. The real-time video display shows the live video feed from the LRAD-RX™ and is used to acquire targets for communication.
