Where shrinkage comes from
Supermarkets lose stock in four main ways: shoplifting, billing fraud at checkout (items not scanned, false voids and refunds, “sweethearting” for friends), losses at goods receiving (short deliveries accepted), and internal theft from stores. CCTV helps with all four, but only when cameras are placed for each risk rather than spread evenly across the ceiling.
Camera plan
- Entrance and exit: faces of every shopper, plus a view of the exit gate or security check.
- Each checkout: an overhead view of the scanner, belt and bagging area, and a view of the cashier and customer.
- High-value aisles: personal care, dry fruits, chocolates, liquor (where sold) and electronics.
- Aisle ends and blind corners where concealment happens.
- Goods receiving bay: vehicles, unloading and counting.
- Back store and cold room doors.
- Cash office and safe.
- Parking and trolley bay.
POS text overlay
Linking the billing system to the CCTV recorder lets each line of the bill appear as text over the checkout video. Managers can then search for voids, refunds, discounts or no-sale drawer openings and jump straight to the matching clip. It is one of the most effective tools against checkout fraud and is supported by many NVRs and video management systems.
Receiving and back store
Short deliveries accepted at the receiving bay are a hidden source of shrinkage. A camera covering the unloading area and the receiving desk, with goods counted under its view and the invoice time recorded, lets managers check disputed deliveries quickly. The back-store door and the cold-room doors should be covered too, since stock leaving through the back is harder to notice than shoplifting at the front.
Using footage day to day
- Review voids, refunds and no-sale openings weekly using POS overlay search.
- Check receiving clips for any delivery disputed by a supplier.
- Use people counts to plan staff at checkouts by hour.
- Share clear images of repeat shoplifters with staff, following your policy.
- Export incidents immediately for police complaints or insurance.
AI analytics that help
- People counting at the entrance for staffing and conversion rates.
- Queue length alerts at checkout.
- Heat maps showing which aisles attract customers.
- Loitering alerts in high-value aisles.
- After-hours intrusion alerts.
Storage, rules and privacy
Supermarkets where 100 or more people gather at a time fall under the Karnataka Public Safety Act, with CCTV required at entries, exits and common areas, including parking, and 30 days of recordings. Display CCTV notices at the entrance. Keep the NVR in the manager’s office or a locked rack on UPS, and limit export rights to managers.
Visible deterrence
A public-view monitor at the entrance showing shoppers on camera is a strong deterrent to casual shoplifting. Combine it with well-lit aisles, clear sightlines and staff who greet shoppers. SightShield installs IP camera systems only, from CP Plus, PRAMA, Honeywell and Hikvision, using models certified for sale in India, with a GST invoice and an annual maintenance contract.
