Warehouse yards generate motion. Rain, headlights, litter, wildlife, tarpaulin. If every pixel change is an alarm, operators learn to ignore the lot. Warehouse video analytics are only useful when they shrink that noise to events a person will still treat as real at 2am.
That is the opposite of buying “AI” as a sticker on a camera. It is rules, angles and a workflow tied to CCTV you can actually use. We wrote about the physical side of the yard in how warehouse yards get hit after hours. This is what you do with the pictures.
What is worth detecting on a yard
- A person on the fence line after close
- A vehicle on the apron outside booked windows
- A shutter or pedestrian gate that stays open
- Loitering at a dark corner the lighting does not cover
What is rarely worth a 3am call: a fox, a tree, a plastic bag, headlights on the ring road. If your analytics cannot tell those apart on this site, they are not ready for a control room.
The camera still has to be in the right place
Analytics will not invent a view. A camera pointing at the building face will not classify a climb on the far palisade. Height, overlap and lighting decide whether a person on the fence is a blob or a usable target. PTZs help once an alarm exists. They are a poor substitute for a fixed camera on the line.
On industrial sites we set analytics after the survey, not before. The fence, the bay and the staff car park are different problems. One global sensitivity setting is how you get 400 alarms on a windy night.
Tie analytics to doors and PIDS
A fence sensor plus a camera rule is stronger than either alone. The PIDS says something touched the line. The camera says what. Loading bay shutters should be events in the access system, with a camera that confirms the dock, not a motion trip on the whole elevation.
Measure the rubbish
If you do not count false alarms, you cannot improve them. Ask for a week of events, by cause. Then tighten. Operators who trust the list will handle a real climb. Operators who do not will miss it.
A practical checklist
- Do you know how many alarms last week were useful?
- Is each rule tied to a purpose (fence, bay, after-hours person)?
- Can an operator open the matching camera from the alarm, in one click?
- Are lighting and camera views good enough for a human to confirm?
- Have you excluded roads, trees and known wildlife paths?
- Who reviews the rules when the site changes a yard layout?
