Lock clips from auto-delete. Hash them with SHA-256 at lock time. Share with counsel, insurers, and law enforcement over signed, revocable, watermarked links, with a full audit trail of every access.
A clip is not evidence until you can prove it is authentic and untampered. Evidence Lock is that proof.
Judges and juries throw out video evidence that cannot be proven authentic. SHA-256 hashing at lock time and an unbroken audit trail are the standard artifacts attorneys look for. Visylix makes them automatic.
Your nightly retention job does not know which clip a lawsuit will be filed over next week. Evidence Lock is the button that tells the retention job "not this one." Preserve the minute the moment it becomes interesting.
Sending evidence via email or Dropbox is a chain-of-custody disaster, you lose visibility the instant the file leaves your system. Signed, revocable, watermarked share links keep you in control until the recipient is done.
Lock, hash, share, watermark, audit, export. No extra tools required.
Locked clips are exempt from the nightly retention job. They stay until explicitly unlocked, even when they are years older than your rolling retention window.
Hash computed at lock time, stored in clip metadata, verified on every subsequent access. Single byte changes → hash mismatch → tampering detected. Pro and above.
Cryptographically-signed short-lived tokens. Recipient views without a Visylix account. Revocable instantly. Every access logged with IP, timestamp, user agent.
Shared clips carry a visible watermark: case ID, recipient name, timestamp. Deters leaks and makes provenance clear on any screenshot or screen recording.
Pro tier: send one clip to counsel, insurer, and law enforcement with independent expiry dates and independent access logs per recipient. Track who watched what, when.
Single-file export: clip, SHA-256 hash, audit log, camera manifest (make/model/firmware/location), and a human-readable custody timeline. Ready for handoff to prosecutors.
Basic lock on every plan. SHA-256 chain-of-custody and multi-recipient sharing kick in on Pro.
Every lock, hash, share, and access is a signed event. Export with one click.
Safety officer locks the clip within hours of the incident. SHA-256 sealed. Six months later, when the claim reaches deposition, the hash verifies byte-for-byte identical to the sealed state. Case closed.
Loss-prevention operator generates a 7-day share link for the responding detective. Watermarked playback, audit log of every view, automatic expiry. No MP4 attachments in emails, no leaked clips.
Basic Evidence Lock is included on Starter and above. Pro unlocks SHA-256 chain-of-custody and advanced case sharing.
It prevents a clip from being auto-deleted by the retention policy. When you lock a clip, Visylix marks it as "held", the nightly retention job skips it even when it is older than the configured retention window. On Pro and above, locking also computes a SHA-256 hash of the clip bytes and writes it to the clip metadata. Any later modification changes the hash, proving tampering. The hash, plus every subsequent access, forms a chain-of-custody trail visible in the admin audit log.
Starter gets basic Evidence Lock, a clip marked locked cannot be auto-deleted. Pro adds SHA-256 chain-of-custody (hash computed at lock time and verified on every access), time-limited external share links, visible watermark on shared clips, and the ability to designate multiple recipients with custom per-recipient expiry. Enterprise adds programmatic API access for case-management integrations and court-export bundles that ship with the full audit log packaged alongside the clip.
An operator generates a share link for a locked clip. The link carries a short-lived, cryptographically-signed token. Recipient opens the link, no Visylix account required, and can view (or download, depending on policy) the clip until the token expires. Every access is logged: timestamp, source IP, user agent, referrer. Starter tier supports one recipient per share. Pro supports multiple named recipients with per-recipient expiry and per-recipient access logs. All shared playback carries a visible watermark with the case ID and recipient name.
The SHA-256 hash and the signed audit log together provide the chain-of-custody documentation that most jurisdictions require for video evidence. Visylix produces court-export bundles that include the clip, the hash, the audit log, metadata about the capturing camera (make, model, firmware, RTSP URL, location), and a human-readable timeline of custody events. Admissibility is ultimately determined by the court and jurisdiction, but Visylix provides the technical artifacts prosecutors and defense attorneys will ask for.
Yes. Every share link can be revoked at any time from the admin console, instantaneously invalidates the token, blocks further access, and writes a revocation event into the audit log. You can also see live access stats per share (views, downloads, last access) and choose to extend or shorten the expiry without generating a new link.
