Retrace
Find them by what they wore, never by who they are.
Point at someone on a frame, upload a still, type a plate or simply describe them. Retrace turns it into words, searches every camera you can see, and returns ranked leads with the reasons. A person decides every sighting.

Start from anything
Five ways to begin a search.
Draw a box on a frame
On a live view or an event snapshot, box the person or vehicle you mean.
Upload a still
A frame from another system or a photo from a member of staff.
Type a number plate
Exact matches first, then plates a camera could easily have misread, then near misses.
Describe them
"Grey hoodie, red trainers, carrying a long box." Typed searches and plates cost nothing.
Ask the assistant
Attach a photo in the assistant and ask where that person went next.
It is described once
The probe becomes a fixed vocabulary of clothing, colours, items and vehicle details. The words are searched; the pixels are never compared with footage.
Ranked, with reasons
Bands, not percentages. A percentage reads like identity.
Every hit shows what matched, what was missing and what conflicted. Rare details count for more than common ones on your cameras, so twenty white shirts stay weak and the one with red trainers rises to the top.
Part of the same visit KENAEZ already tracked, with nothing in the description contradicting it.
Distinctive matching detail with no conflict, or an exact plate read. Look at these first.
Some agreement, or a description that was not written from that exact frame. Judge from the image.
Common details only. Shown so nothing is hidden, ranked so nothing is overstated.
Re-examine the top results and each candidate is described again from its own still. Your match and not-match calls re-rank the rest.
Cases
From lead to evidence you can hand over.
- Nothing is a sighting until an operator confirms it
- Confirming copies the still and clip into the case with a SHA-256 checksum, so evidence outlives normal retention
- A journey map of confirmed sightings across sites and time
- Two sightings that could not both be true, given the travel time, are flagged for you to resolve
- Status, priority and an assignee for handover between shifts
- A PDF report and a ZIP whose SHA256SUMS file anyone can verify with standard tools
Sharing evidence
The right export for the right recipient.
| Export profile | Who it is for | Bystanders | Video |
|---|---|---|---|
| Police | Law enforcement requests | Originals | Included |
| Third party | Insurers, solicitors, clients | Everything outside the subject's box pixelated | Withheld |
| Subject access | The person who was recorded | Everything outside the subject's box pixelated | Withheld |
Video is withheld from redacted exports because a fixed box cannot follow a moving person. View-only share links expire after 24 hours, 72 hours or 7 days, and every view is logged.
Safeguards
Powerful enough to need rules. So it has them.
Never biometric
No face matching, no face or body template, no image embedding. An automated test fails any release that tries.
Scoped to your cameras
Every search and every case shows each user only the cameras they are allowed to see.
Audited for a year
Every case, probe, search, verdict and report is an append-only audit record kept for 365 days.
Reason required
Your organisation can require a reason for every search and restrict Retrace to administrators.
Kept only as long as needed
Untouched drafts go after 7 days and closed cases after 90 by default, with their images and evidence.
People only
Guests, WhatsApp and external AI connections can never reach Retrace. It is for your own signed-in operators.
Apparent characteristics are off by default
An organisation admin can choose to include apparent sex, age band, build and similar attributes, but only after recording a lawful basis for special category data. When on, they are always labelled as apparent, can be wrong, weigh no more than clothing, and can lower a result by one band at most, never exclude it. Health, disability, gait and religion are never recorded.
