Analyze the sound. In pilot
Locate sharp sound events and examine their timing. For aligned recordings, compare when an event reaches each microphone, with timing uncertainty shown.

“The officer used a Taser on a man who was already handcuffed and was not resisting.”
U.S. Court of Appeals for the Seventh CircuitKingsley v.
Hendrickson
801 F.3d 828, 832 (7th Cir. 2015) (per curiam)“Our precedent makes clear that when the officers applied the Taser to Mr. Kingsley in May 2010, use of the Taser violated Mr. Kingsley’s right to be free from excessive force if he was not resisting.”
The next question
Read page 832 on CourtListener ↗Was he resisting? In Abbott v. Sangamon County, from the same search, a handcuffed man kept fighting, and the officer was entitled to qualified immunity.

03 · Spatial intelligence
Research in developmentCompare the views.
Examine sightlines.
Our spatial research explores how separate camera views fit together, what blocks a view and what the recordings leave unseen.
This is an actual early North Avenue geometry study. It is partial and unscaled; it cannot yet establish distances or reconstruct the incident.
Explore the researchUnder the hood
Built to be checked.
The parts you don’t see are what make it hold up: answers show where they came from, and gaps are listed, not hidden.
Where the record disagrees with itself
Reports, recordings, dispatch and 911 audio are read against each other. Each difference cites both sources, and agreements are listed too.
Transcripts that keep the shouting
That is all a widely used speech filter kept of one public body-camera recording. Audible stretches are decoded again, and anything still unclear is listed for you to hear.
Sentences without a source are cut
On one public matter, the checks removed 195 statements whose numbers the source did not contain. What remains cites a page or a second.
A second AI checks the first
A description of what is on screen is kept only when a model from another company agrees. Otherwise the moment is marked as not describable.
It shows what it did not examine
Each recording carries a checklist of what ran, what ran partly and what did not, so the gaps are visible instead of hidden.
Citations carry the file’s fingerprint
Exports and notes record the fingerprint of the original file. A draft whose original has changed is refused.
In pilot
The police radio is a hidden clock.
Matching the same dispatch transmission across body cameras lined their clocks up to within a few milliseconds in our pilot, showing which camera heard a sound first. It never says what made the sound.

A few useful answers
Before you begin.
What does Vizion Labs do?
Vizion Labs helps legal teams analyze recordings and documents, find relevant moments and keep findings linked to their sources. Sound analysis examines events and timing; legal research helps investigate the issues the record raises.
Where can this reduce review costs?
In the hours spent finding relevant footage, repeating searches and locating material already reviewed. Timestamps, searchable analysis and saved findings reduce that repeated work. A pilot can measure the time saved against your current process; the benefit depends on your evidence and review task.
What can I review?
Review a selected recording segment or document pages, or search analysis already completed for a matter. Available results depend on which sources have been processed. Linked recording groups currently require separate review. Sound analysis is scoped to supported recordings during a pilot.
Does a box identify who someone is?
No. A person track follows a visible figure over a bounded interval; it does not establish identity. The blue police labels in this example were reviewed against visible uniforms and markings. Grey Person boxes mark other people the tracker followed; they claim no role. Detection can miss people and tracks can change subjects.
Is scene reconstruction available today?
Spatial intelligence is in development. The North Avenue study is partial and unscaled. A measured reconstruction requires sufficient source material, calibration, established scale and validation.
Security
Control access to your evidence.
Keep evidence organized within authorized workspaces. Confirm deployment, access and retention requirements as part of your pilot.
Review security and data handling
Where it is stored
Amazon Web Services in the U.S. (N. Virginia), encrypted at rest with AWS KMS, public access blocked, versioning on.
Original evidence
Original files are retained separately from machine-generated results. Review the source identification and retention arrangements for your matter.
Matter access
Signing in does not grant access to every matter. Workspace membership and matter permissions determine the evidence a user can open.
Sign-in
Sign in securely with your account. Workspace membership determines which matters you can open.
Downloads
Evidence downloads require authorized matter access. Storage credentials are not supplied to the browser.
Automated evidence processing
The automated evidence pipeline runs in our AWS account in the U.S. Cloudflare serves the website and video streaming. Confirm the hosting and data handling of any additional research services before your pilot.
What we do not claim: security certifications, a separate environment for each firm, or write-once storage. Deployment and retention terms are agreed with you in writing before a pilot.
