Targeted, Steerable Audio Surveillance
InSight Acoustics HyperMic™ system provides source specific Audio-Scoping onto any point or Person, stationary or moving, in a coverage area during any period of time, past or present.
The HyperMic™ system, including 4D Audio & Video recording, enables post-facto audio-scoping onto any subject appearing in the recorded Video (On-Line & Off-Line investigation).
Real-Time & Forensic Audio-Scoping
4D Audio Beamformer Processing / Live Scene Capture
Crashing through the sound Capture Barrier
InSight Acoustics HyperMic™ Technology uses a synergistic fusion of optical and acoustic array sensors (codename: HyperMic™ Sentinel) to provide a set of (1 till 100) optically guided virtual directional microphones.
A HyperMic™ Sentinel unit can optically track each of a set of multiple people, or any selected sound sources (e.g. Targeted People talking in crowd), estimate a relative direction to each person or source of interest and concurrently steer a separate individually virtual directional microphone at each source of interest.
The output of each virtual directional microphone is a digital audio stream whose audio content is predominantly comprised of sounds arriving form the direction of the selected source.
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.
Assembled With a Fixed Array of Omni-directional Mics, Camera(s) and Embedded ProcessingMic Array With Aggregated Coverage of 360° & Overlap Coverage Areas
