Critical Infrastructure Security Systems

Securing Critical Infrastructure

Throughout the world, LRAD 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.

Remotely operated LRAD-RX systems provide 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 voice commands and warning tones to safely establish 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.

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.

Embassies & Government Facilities
Tower-mounted LRAD-RX systems provide enhanced embassy and 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.
