Chain of custody, recorded by the system rather than reconstructed later: every view, download, export and refused access written into a tamper-evident chain, every stored file fingerprinted and signed, every export verifiable by someone who has no access to us at all.
Custody logs written by hand are only as good as the person filling them in, and they are the first thing a defense attorney attacks. Here the record is a by-product of using the system: nobody has to remember to write it down, and nobody can quietly rewrite it afterwards.
Every view, download, export, deletion — and every refused access — is written into a per-tenant hash chain, each entry sealing the one before it. Nightly, the chain is anchored with a cryptographic signature. Altering yesterday's history breaks today's math.
Every stored file gets a SHA-256 fingerprint as it is written, recorded in an Ed25519-signed manifest. A janitor re-verifies random samples around the clock, so a silently corrupted file is found by us before it is found in court.
Once an original lands in the archive it is written once and left alone. Exports compare bytes against the recorded fingerprint and refuse to produce a file that does not match rather than handing you something quietly different.
Officers check in at the start of a shift with name and badge. Everything the body-worn camera captures for that shift is attributed to the officer who was wearing it — answered at upload time, not reconstructed from a duty roster months later.
Pull timeline ranges, clips, gunshot and SOS events and GPS tracks into a case under your own agency case number. The material is copied in, so it outlives the seven-day breadcrumb prune and the ordinary recording cycle.
Evidence is copied out of the 30-day cycle into retention categories with day counts set by statute and anchored to capture time. A legal hold beats every clock. Automatic purges emit a signed deletion certificate saying exactly what went and when.
Deleting evidence takes two different admins — one to request, another to confirm. And the vendor is not one of them: we have no route to delete your evidence, which is the only version of that promise worth anything.
When signal drops, body-worn cameras record locally and upload later with device-side hashes and contiguous sequence numbers. A missing segment is visible as a missing sequence number — the one property a dead-zone story needs.
Export the custody record as CSV with the chain and its signed anchors. Opposing counsel runs a small verification script offline — no account, no portal, no request to Nevtech — and either the chain checks out or it does not.
Your evidence can be verified by people who don't trust us. That's the point.
Evidence Management is CJIS-aligned and ready to go — but CJIS compliance is achieved per agency, not bought off a shelf. What we do is meet the technical controls of the CJIS Security Policy and sign the Security Addendum with you. Your agency's CSO or CJIS systems officer still owns the audit; our job is to arrive with the technical half already done rather than as a project you have to finish.
Ask for our CJIS program sheet when you book a demo and we'll send the control-by-control detail before you spend a meeting on it.
Discovery normally means burning a disc, zipping a folder, or — worst of all — creating a login for someone outside the organization. Every one of those ends the custody record at the moment it matters most. A share link keeps the record running: the recipient watches, and the watching is part of the file.
Redaction works the same way. Blur boxes and muted audio ranges produce a new derivative clip; the original is never touched and the redaction log is kept, so you can show what was obscured and why without anyone wondering what happened to the source.
When a case leaves the building — to a prosecutor, a defense expert, an auditor, a records request — someone has to explain the chain of custody. Usually that's a person reconstructing it from memory and screenshots. Here it's a button: the Custody & Compliance Report lays out every item's journey (which camera, which officer at check-in, how the file arrived, its cryptographic fingerprint, where the protected copy lives), the complete access history including refusals and share-link opens by name, and the platform's security posture in plain language. Print it to PDF from the browser and hand it over.
The part reviewers notice: a missing-elements section that is computed, not written. Unattributed footage, an upload gap, material with no durable copy, a retention clock running with no hold on it — if something would weaken the file, the report says so to you first, before opposing counsel finds it.
Most organizations discover they needed a custody record about eleven months after the incident, when a claim turns into a deposition. The same machinery agencies use for criminal evidence handles a slip-and-fall, a termination, a shrink investigation or a damaged shipment — same audit chain, same signed fingerprints, same exports.
Build the incident file once — timeline ranges, clips, events — and it stays intact under your own reference number long after the ordinary recording window has rolled over.
Send the adjuster an expiring, revocable link instead of a file transfer. You can say who opened it and when, because the system wrote that down without being asked.
Sensitive footage attracts curiosity. Every view — and every attempt that was refused — is logged, which is as much a protection for your staff as it is a control on them.
Place a legal hold and the automatic deletion schedule stops for that material. Nothing ages out mid-dispute because somebody forgot to extend a retention setting.
Blur the bystanders, mute the ranges you must not share, release the derivative. The original stays exactly as recorded, which is what makes the derivative defensible.
Sign out everywhere, admin revocation of any user's sessions in seconds, a 30-minute inactivity timeout and an authorized-use notice at sign-in — included for every customer, no add-on required.
The audit and integrity substrate records for every Nevtech customer today, whether or not the add-on is switched on. So buying Evidence Management later does not start the clock — it unlocks the history that has been accruing since your first camera came online, alongside everything that happens after.
The court CSV export contains the custody entries, the hash chain linking them, and the signed nightly anchors. Anyone — opposing counsel, an outside expert, your own auditor — runs a short verification script against that file on their own machine. They need no account with us, no network access to us, and no cooperation from us. That is deliberate: a custody proof that depends on the vendor's goodwill isn't a proof.
No. Deleting evidence requires two different administrators inside your own organization, and the vendor has no route to do it at all. Automatic purges — the ones your retention categories schedule — produce a signed deletion certificate recording what was removed and when, so an empty shelf still has an explanation attached to it.
The camera records locally and keeps going. When signal returns it uploads with device-side hashes and contiguous sequence numbers, so the footage arrives with proof of what it is and where it sits in the sequence. If a segment genuinely didn't make it, the gap in the sequence numbers says so out loud — the failure mode we refuse to ship is a recording that quietly stops and never mentions it.
Never. Blur boxes and audio mutes render a new derivative clip; the original file is untouched and still matches its recorded fingerprint. The redaction log is preserved too, so you can account for what was obscured without producing the unredacted material.
No — it is the same console, the same cameras and the same timeline. Cases are built from footage you're already watching, and body-worn and fixed cameras feed the same evidence store. There is no second portal and no export ritual between the two.
Then you found it first — which is the point. The missing-elements section is computed from the records at the moment you generate it, and it will name an unattributed segment or a missing copy to you in private long before it becomes a cross-examination question. A report that only ever says "everything is fine" would be worthless the first time it wasn't.
Every recording carries a SHA-256 fingerprint from the moment of capture, every access and export is written to a hash-chained audit log, and exports ship with signed manifests that verify offline — a court can confirm footage is unaltered without trusting Nevtech or your operators. Legal holds, deletion certificates, and redaction that never touches the original complete the custody record.
We'll build it live — case file, custody chain, redacted release, and an export you can hand to someone who has every reason to doubt it.
