Product overview

The product, one screen deep.

NexBasira is a video-first inspection tool where every event in a session — joins, snapshots, annotations, whiteboards, signatures — lives in an append-only hash chain anchored to public timestamp authorities. Pick a sub-page below for the deep dive.

Compliance

Audit chain + TSA anchoring

A per-session SHA-256 hash chain, cross-checked at session close against independent timestamp authorities — a public blockchain and an eIDAS-qualified RFC 3161 authority — so the record of what happened can't be altered after the fact.

Capture

Composite + per-participant recording

Record the full composite (operator + field side-by-side) and isolated per-participant audio + video. Annotations burned in, sealed in the audit chain, and retained in your own storage to eIDAS standards.

Capture

In-session collaborative whiteboard

Excalidraw-based shared canvas every participant sees in real time. PNG + Excalidraw-state both anchored to the audit chain — tampering with either side fails verification.

Legal

eIDAS-tier signatures (SES / AES / QES)

Three tiers on the same audit-report PDF. QES gates behind KYB verification of the issuing organisation. PAdES B-T baseline today; PAdES B-LT for long-term verification on the v1.5 roadmap.

Integration

Public API + SDKs + embed widget

Four first-party SDKs (Node, Python, Embed iframe, React component) over a versioned REST API. Cursor pagination, Idempotency-Key headers, HMAC webhook signing, async-iterator helpers — the developer-experience pieces that should be there.

Session lifecycle

A session moves through five states, mirrored in the audit chain.

State
What happens
Created
Operator (or API) creates the session. A one-shot signed invite URL is minted for the field user.
Open
Field user joins via the link. Consent + GPS + camera permissions captured on-screen. Audit chain opens with `session.created` + `consent.granted` events.
Recording
Optional composite + per-participant recording starts. Snapshots, annotations, whiteboard sessions all land in the chain in real time.
Closed
Operator ends the session. Chain head is timestamp-anchored to three TSAs in parallel. Recording post-processing kicks off.
Reports ready
Audit report + inspection report PDFs render with branding. Signed PDF available if the org has cleared KYB.
