LRAD ONE VOICE® Command & Control Software

The LRAD Command and Control Software provides ONE VOICE technology that is scalable and flexible as a stand-alone system or easily integrated with 3rd party software and equipment for a comprehensive
package. The application is customizable from a Graphic User Interface and feature set to fit any needs from one to thousands of activations. The system is designed to accept C AP and provides flexibility to quickly create or automate polygon activation.

Software activation monitoring through IP, digital with immediate activation and live broadcasts. Systems flexibility enables easy integration with cell phones, existing systems and traditional analog technology.

The LRAD Command and Control software system’s primary interface supports the following functions and features: Stream Live or Prerecorded audio to a single speaker array, user defined groups of speaker
arrays or All Call using a map based GUI. Speaker arrays can be grouped in zones for targeted messaging.

Audio can be transmitted in TCP/IP, RTP or SIP over VPN or a Multicast compatible network. In TCP/IP mode, the included software allows users to set “priority” levels for each site to program the main control center with the ability to control local or regional command centers.

LRAD’s omnidirectional ONE VOICE® systems combine warning sirens and highly intelligible voice broadcasts to provide advanced mass notification and public address solutions. Antiquated warning systems sound sirens to alert of approaching danger, but most are incapable of clear voice broadcasts containing critical information about the severity of the situation and recommended actions to protect and save lives. LRAD mass notification systems are also used to communicate to crowds during large, outdoor events and to affected populations throughout emergency situations. LRAD systems are self-contained or easily integrated with existing communications infrastructure.
