Directionality, Output & Range

  • Clear, Long-Range Directional Communication
  • Reduces the risk of exposing nearby personnel to excessive audio levels



  • Remote capability – TC/IP Addressable
  • Respond to a Threat from a Safe Environment
  • Low Power Requirements
  • All-Weather Use
  • Fixed Infrastructure


Cost Effective

  • Increased Security Coverage
  • Reduced Manpower
  • Improved Operational Efficiency
  • Increased Response Capabilities

LRAD-RX uses its directionality and focused acoustic output to clearly transmit critical information, instructions and warnings well beyond 3,000 meters. Through the use of powerful voice commands and deterrent tones, large safety zones can be created while determining the intent and influencing the behavior of an intruder.


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