Dropped-Object Zone Monitoring
Detects people entering the zone beneath a suspended load, crane swing radius or overhead work area, and flags objects and materials falling from height.

What it detects
The zone under a lift is a defined space with a defined rule. These are the events Fogsphere identifies against it, on the cameras already covering the lift area.
Personnel beneath suspended loads
Identifies a person entering or standing in the area directly under a suspended load, while the load is in the air.
Crane swing radius and exclusion zones
Flags entry into the swing radius and configured exclusion zone around cranes, excavators, telehandlers and lifting equipment.
Red-zone breach under lifting operations
Detects breaches of the marked red zone during active lifts, with the lift, camera and duration logged against the event.
Objects falling from height
Surfaces tools, components and materials falling from elevated work areas, scaffolds, decks and structures.
Swinging loads near workers
Identifies loads, pipes, collars and slung materials swinging within proximity of people on the deck or floor below.
Load-path intrusion
Flags people crossing the planned travel path of a load between pick and set-down points, not only the endpoints.
Lifting and material-handling exclusion zones
Covers loading exclusion zones, dock-edge lift areas and material-handling zones where entry during operation is not permitted.
Unsecured tools and materials at height
Detects tools and materials placed near unprotected edges, openings and deck gaps from which they could fall.
Unsafe rigging-area access
Surfaces people entering rigging, slinging and load make-up areas outside the rigging party.
Stack and laydown area intrusion
Flags entry into container stacks, pipe racks and laydown areas where stored material can shift or topple.
Barrier and barricade crossing
Detects people crossing the temporary barriers and barricades that define a dropped-object zone.
Where it applies
Dropped objects and suspended-load zones appear in the oil & gas, power-generation, construction, manufacturing, chemical and logistics papers. Offshore drilling and port lifting operations describe it in the most detail.
How it works
Edge inference on the cameras you already have
Detection runs on cameras covering the lift area, drill floor or deck. Zone geometry is defined on the camera view, so a zone can be redrawn as the crane, the load path or the work front moves.
Zones, thresholds and schedules you configure
Set the exclusion-zone shape, the active condition (load in the air, crane slewing, work overhead) and the roles permitted inside it. Temporary lifts can carry a zone that is only active for the duration of the permit.
Every event carries its own evidence
Each detection is logged with a timestamp, the camera and zone it came from, and a short clip. The record can be reviewed, exported or attached to an investigation without trawling through hours of footage.
Feeds the systems already in place
Events surface in Fogsphere Manager and route outward to the VMS, access-control platform, control-room wallboard, ticketing queue or messaging channel operators already watch.
Risk & control objective
The control objective is keeping the zone under a load clear, and having a record of the times it was not. Lift plans define the zone; barriers mark it; what nobody has is a continuous account of who crossed it and when.
The measurement is genuinely difficult by any other means. A banksman watches one lift at a time. On a drill floor, a port quay or a multi-storey structure there may be several concurrent, each with a moving zone geometry, and the exposure lasts only as long as someone is in the wrong place. That is a duration a person is unlikely to record and a camera is well placed to.
Treated as a leading indicator, the same events change what can be managed. Red-zone breach frequency by crew, shift and lift type is a number that moves before an incident does — and unlike incident counts, there is enough of it to act on.
