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™

by Insight Acoustics

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

HYPERMIC™

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
