VLM output
An overhead CCTV camera watches a narrow retail aisle between stocked shelves as a single person in a black hooded jacket and dark trousers walks along the aisle, pausing and turning toward the left-hand shelving. Across the four frames the person moves down and toward the left shelves, hood up and face largely obscured, with no other people or staff visible.

Customer challenges
Prolonged loitering can signal theft intent or a safety issue but can't be tracked manually across the floor, and blocked exits and aisles are common safety and compliance violations that go unnoticed until an inspection or emergency.
Customer benefits
Early awareness for loss-prevention with deterrence, focused staff attention, and reduced shrinkage — while keeping egress and aisles clear to reduce audit findings and stop blocked paths from making emergencies worse.
