Same engine. Investigation-grade record.

SteadCalm gives police, council enforcement and investigation units one place to capture visual evidence, recall candidates from the registers they control, verify with a human in the loop, and hold a chain of custody that survives disclosure — persons of interest, stolen property, vehicles and plates on the same pipeline.

Chain of custody · Evidence workflow

Capture → Recall → Verify → Record → Share.

Five steps, one unbroken record. Each step writes its own custody entry, so the question "who touched this exhibit, when, and what did the system actually return?" has an answer before anyone asks it.

  1. 01 · Capture

    Photo, video, live camera or uploaded file is ingested from any device. Operator, device, GPS, timestamp and a SHA-256 content hash are written at the moment of capture — before anyone looks at it.

    Exhibit created · hash sealed
  2. 02 · Recall

    Vector embeddings retrieve candidate records from the active register — persons of interest, stolen property, vehicles, plates — using nearest-neighbour search scoped to the caller's clearance.

    Match run opened · register + scope logged
  3. 03 · Verify

    A second-pass model re-scores every candidate and returns a confidence band. Borderline results route to a human reviewer with full context. The system never auto-identifies.

    Scores, model version and thresholds retained
  4. 04 · Record

    Candidate list, scores, reviewer decision, notes and linked incident are written to an append-only log alongside the exhibit — nothing can be edited or deleted after the fact.

    Immutable audit entry · named operator
  5. 05 · Share

    Disclosure packages export as signed bundles to named agencies, with a re-hash on export proving the exhibit is unaltered. Every transfer records recipient, purpose and time.

Investigative capability

What you can point it at.

A person, a bike, a plate, a two-hour clip or a folder of body-worn footage — the intake is the same and so is the record it leaves behind.

Facial recall & verification

Two-stage matching — broad vector recall, then a verification pass with adjustable sensitivity per organisation and a mandatory review band.

Plate & vehicle recognition

Plate OCR plus make, model and colour attributes matched against your vehicle and BOLO registers, with GPS and time on every hit.

Stolen property matching

Serials, engravings and visual similarity across property reports — a bicycle on a footpath checked in the time it takes to walk past it.

Video analysis & tracking

Frame sampling across a clip, multi-subject tracking with persistent subject IDs, and an event timeline you can scrub and filter.

Cross-capture search

Free-text and attribute search across every capture and detection your clearance permits — one query, whole case load.

Standing alert rules

Watch-list rules fire the moment a subject, plate or item is seen, notifying the right unit with location, confidence and the capture itself.

Stolen-vehicle cross-matching

Registered stolen plates matched against every field plate read, OCR-normalised and scored on plate similarity, recency, proximity to the theft and corroborating vehicle detail — with the evidence behind each score.

Repeat-pattern early warning

Areas where lodged reports are recurring, with trend and confidence, plus repeat-pattern warnings routed to the responsible coordinator, dispatcher or command. It prioritises human review of reported incidents; it does not predict or profile individuals.

Cited tactical briefings

AI briefings grounded on a numbered fact ledger — every paragraph cites the events, reports, assets, plate reads and images it used, uncited text is flagged, and each run is retained in an audit trail.

Incident reports

Assembled narrative, exhibit list, match provenance and audit extract — exportable as a PDF brief ready for a supervisor or a prosecutor.

No match, no record

Records & evidentiary integrity

The match is not the product. The record is.

Any vendor can show you a green tick on a face. What decides a matter twelve months later is whether you can show the exhibit is unaltered, the search was authorised, the threshold was set before the search rather than after, and a named person made the call.

SteadCalm is built so that record is produced automatically as a by-product of doing the work — not assembled by an analyst the week before a hearing.

Police overview (PDF, 2 pages)

Content hashing

Every exhibit hashed at ingest. A re-hash on export proves the file produced in court is the file that came off the device.

Immutable audit

Every view, match run, threshold change, export and role grant is appended and cannot be edited or removed — including by administrators.

Match provenance

Model, version, threshold and score retained per candidate, so a defence expert can reproduce or contest the result.

Human decision of record

The platform produces candidates, not conclusions. Every identification is attributed to a named operator at a recorded time.

Governance & legal basis

Constrained on purpose.

Off by default

The investigative registers do not exist in a venue console. They are enabled per organisation, under written authority, and each activation is audit-logged.

Clearance in the database

Security, Licensee, Coordinator, Police and Admin roles are enforced by row-level security — a police account cannot reach a venue-scoped record the ban scope doesn't release.

Your infrastructure

Registers, retention windows and residency follow your agency's policy. Nothing is forwarded to third-party or national systems unless you configure it.

Retention & purge

Per-register retention with scheduled purge and a purge log, so deletion is as auditable as capture.

Two operating contexts · One platform

Screening at licensed venues is conducted under displayed conditions of entry. Investigative use of the identification pipeline by police or law-enforcement users requires a warrant or statutory power, is off by default, and every activation is audit-logged. This page is an overview, not legal advice — deployment requires local legal review.
