Your shelf keeps a ledger.
TrackBack turns the cameras you already own into shelf-level analytics — every pick-up, put-back and pause, recorded as anonymous events. Know what almost sold, and prove which placement earns its keep.
Entry № 01 — The blind spot
POS sees the sale.
Not the almost-sale.
Your till records what sold. It never saw the shopper who lifted the jar, read the label, checked the price — and put it back. That moment is the most honest feedback in retail, and it goes unrecorded in every store, every day.
The ledger your till never kept.
Entry № 02 — The signal
Three events.
Cameras you already own.
A hand lifts the product off the shelf. Interest, made physical — the metric your bestseller list is built on, now visible before the till.
Returned to the shelf. Interest that didn't convert — the loudest silent feedback in the store: wrong price, wrong size, wrong words on the pack.
Seconds spent engaging with a zone. Attention, measured — which displays stop people, and which ones they walk straight past.
No faces. No identities. No video ever leaves the device — see how.
Entry № 03 — The retrofit
Fitted in an afternoon.
A small box beside your router. Your existing cameras connect to it — no new hardware on the shop floor, no rewiring, nothing shoppers can see.
Vision runs on the box, inside the store. Footage is read and discarded on the spot; only anonymous events leave: zone, action, timestamp.
The dashboard turns the stream into answers — which shelf earns its space, what gets lifted and abandoned, whether the move you made paid off.
Entry № 04 — The proof
Move the product.
The ledger settles the argument.
Record a placement change and TrackBack measures it automatically — pick-ups per day before and after, over matched windows. No more gut-feel debates about eye level.
Illustrative example.
Entry № 05 — The architecture
Private by architecture,
not by settings page.
Video never leaves the store. Frames are processed on the device and discarded in seconds.
No faces, no identities, no following anyone around the shop. Events are anonymous by construction — a zone, an action, a timestamp.
What little data exists lives in the EU, behind a login. GDPR isn't a checkbox here; it's the reason the system is shaped this way.
Put your shelf
on the record.
Pilots run on your existing cameras. If it doesn't fit, we unplug the box and leave no trace.
