Loitering detection — theft has a shape, and it starts with standing still
Loitering detection on CCTV catches the part of an incident that happens before the incident. A person who stands at a high-value shelf, a fence line or a loading bay for far longer than the task requires is the single most reliable pre-theft signal in any site — and it is exactly the pattern a busy human never notices and software watches continuously.
How loitering detection cctv works
Mark the zone
The shelf, the bay, the fence stretch, the parked-vehicle row — anywhere lingering is unusual.
Set a dwell threshold
How long is too long here? Thirty seconds at a jewellery counter; three minutes at a fence.
Exempt the expected
Enrolled staff working in the zone don't trigger it. A queue at a till doesn't either — thresholds are per-zone for exactly this reason.
Alert discreetly
Often the right response is a quiet nudge to a manager's phone rather than a siren. A staff member walking over is the most effective deterrent that exists.
Where it earns its keep
- High-value retail shelves and jewellery counters
- Warehouse aisles holding fast-moving, high-value SKUs
- Perimeter fence lines where someone is assessing a way in
- ATM lobbies, parking areas and society common areas
What it won’t do
Every AI vendor lists strengths. These are the limits, so you can plan around them instead of discovering them.
- Legitimate lingering exists — a customer genuinely deciding, a technician working. Thresholds and staff exemptions carry the weight here, and they need tuning per zone.
- It flags behaviour, not intent. Every alert deserves a human glance before any action, and the system is designed around that assumption.
Loitering & dwell time — common questions
Won't this flag ordinary customers browsing?
Only if the threshold is set badly. Dwell times are per-zone — thirty seconds at a jewellery counter, three minutes at a fence — and staff are exempt. In practice the tuning takes a week and then the alerts become genuinely rare.
Is this the same as motion detection?
It's almost the opposite. Motion detection reacts to movement; loitering detection reacts to a person tracked continuously in one zone without leaving. That requires tracking an identified person across frames, which pixel-difference motion detection cannot do.
What should we do when a loitering alert fires?
Look at the snapshot, and if it warrants it, have someone walk over. Presence is the deterrent. We'd caution against automated sirens on dwell alerts specifically — the false-positive cost is a confronted customer.
