1. 01

   The whole StoreEye

   One ceiling camera per aisle counts shoppers as dots, takes a shelf photo only when nobody is in view, and watches the floor for spills and the wet-floor sign. Staff tap a plaque on each floor walk. Everything lands in one app.

2. 02Brain

   Raspberry Pi Zero 2 W (in the ceiling head)

   The brain: it runs the storeeye-head program

3. 

   03

   AI Camera (Sony IMX500)

   Finds people on the chip for counts; takes shelf stills and floor frames

   Raspberry Pi Zero 2 W (in the ceiling head) · CSI-2 ribbon cable · People boxes, 12 MP stills, small grey frames

4. 04

   Lens window

   Gives the camera a clean view down the aisle; wipes clean

   Raspberry Pi Zero 2 W (in the ceiling head) · Optical path · Light onto the sensor

5. 

   05

   Walk checkpoint

   Proves a staff phone stood at this aisle end on a floor walk

   IEMI cloud · NFC tap to a staff phone, then HTTPS · Signed tap counter

6. 06

   USB Ethernet adapter

   Sends results over the wired cable, not the shop Wi-Fi

   Raspberry Pi Zero 2 W (in the ceiling head) · USB OTG (micro-USB) · Counts every 5 s, tasks and alerts

7. 07

   PoE splitter

   Powers the head from the one ceiling cable

   Raspberry Pi Zero 2 W (in the ceiling head) · 5 V micro-USB lead · 5 V power

8. 08

   Status light

   Green means counting; amber means no uplink

   Raspberry Pi Zero 2 W (in the ceiling head) · GPIO 17 pin · LED on and off

Pricing

Target pricing. For a 6-aisle store, our four products bought separately (ShelfScan 6 cameras $1,794 + $174/month, SpillGuard edge box and 2 domes $597 + $199/month, StoreSense $287 + $15/month, FlowCount 2 sensors $1,798 + $78/month) add up to about $4,476 + $466/month (est.). Parts cost about $132 per head at qty 1 (est.).

Indicative launch pricing in USD, excluding taxes and shipping. Final pricing is confirmed before any balance is charged.

1. 28 Oct 2026, 08:24LatestAn independent grocer needs one thing in each aisle that finds shelf gaps and checks the restock, calls spills and the wet-floor sign, and flags wrong labels. Independents ran 6.6 % out of stock in fiscal 2025 (FMS/NGA via The Shelby Report), and shelf cameras are sold to chains with no public price (Supermarket News).

2. 27 Oct 2026, 10:30Independent grocers have four jobs in every aisle: shelves run empty between shelf walks (independents ran 6.6% out of stock in fiscal 2025, FMS/NGA study), spills wait to be noticed and a slip claim commonly settles at $15–75k (law-firm figures), paper floor-walk logs are easy to back-fill, and owners lose buyers to the till queue without knowing it (Dor counters cost $59–150 a month). Our own four products for it cost about $4,476 and $466 a month for a 6-aisle store.

   • New product StoreEye: one ceiling camera per aisle does the jobs of ShelfScan, SpillGuard, StoreSense and FlowCount, with one Raspberry Pi Zero 2 W brain, one AI camera and one network cable per aisle, and one app
   • Reused CAD parts unchanged: FlowCount's ceiling head base, cover with lens window and T-bar clip, and SpillGuard's walk plaque. New part: a 30° aisle wedge (FlowCount's wedge at a steeper angle) so the camera looks down the aisle. 5 printed parts, each one solid, every bought part fits
   • 3D view: a grocery aisle with a 3 m drop ceiling, the head at the aisle end, two shelf runs with an empty gap, a shopper, a spill with the wet-floor sign, and the walk plaque on the shelf end
   • Dropped: StoreSense's depth-sensor door unit and zone nodes, ShelfScan's battery shelf cameras and store hub, SpillGuard's sign tags and extra cameras, and FlowCount's second node per queue. StoreSense's 'no camera at all' promise is dropped: people are still counted as dots and never stored
   • Product page https://iemilabs.com/products/storeeye/: $2,490 + $129/month for a 6-aisle store instead of about $4,476 + $466/month; parts about $132 a head at quantity 1 (est.)
