InSight Acoustics HyperMic™ Technology for Audio Surveillance

Based on a synergistic fusion of optical and acoustic sensors into a single optically guided acoustic beamforming device.

HyperMic Sentinel 60

PART # IA-2001

Provides Large Distance Audio recording, enables post-factum audio-scoping onto any subject appearing in the recorded Video (On-Line & Off-Line investigation).

HyperMic™ Technology 

ADDITIONAL DIMENSION


An extended version of the HyperMic™ Technology (AKA: CrossBeam™) utilizes two or more synchronized HyperMic™ Modules in order to direct multiple beam-formers from different direction towards the same sound source. CrossBeam™ digital audio stream outputs are time-aligned and cross-correlated to provide for an additional speech capture performance boost.


HyperMic™ Functional


  • Assembled With a Fixed Array of  Omni-directional Mics, Camera(s) and Embedded Processing 
  • Mic Array With Aggregated Coverage of 360° & Overlap Coverage Areas

HyperMic™ Installations

Indoor & Outdoor

AIRPORTS, MALLS, TRAIN STATIONS; MEETING ROOMS, MEETINGS, COURTROOMS, CARS; PRISON, SECURITY PLACES, SECRET SERVICE

  • Several HyperMic ™ can be installed, by creating one system for the better coverage of large areas.
  • By connecting several units, a single person could listen even during his movement to different rooms.
  • HyperMic ™ has auxiliary cameras such as an HD camera and a flyer, which can be used to track one or more people and to receive pulse and body heat

FUNCTIONAL CAPABILITIES


Source Specific Sound and Speech Capture  
With High Level of Background Noise Rejection

HyperMic™ performs on-chip source specific spatial filtration (using beamforming) for one or more selected sound sources, rejecting sounds arriving at the HyperMic™ from all other directions

Real-Time Sound Source Tracking & Sound Capture

HyperMic™ tracks the physical location of the selected sounds sources, as either the source or the HyperMic™ move relative to one another, and dynamically steers a beamformer in the tracked direction

Concurrent Multi-Source Tracking & Sound Capture

HyperMic™ concurrently tracks and dynamically steers acoustic beamformers at each of the selected sounds sources

Multi-Beamformer Synchronization

HyperMic™  provides for precision location specific speech capture at extended ranges within noise filled environments
