Dynamic Area Delimitation
Defines zones that move with the work — crane swing radius, excavation edges, temporary barricades — and re-checks their integrity as the site changes shape.

Zones that move with the work, checked as they move
What it detects
Harvested from the computer-vision use-case columns of the Q3 industry papers. Every item below is a rule you can switch on, tune per zone and report on.
Barricade and exclusion-zone integrity
Checks that a barricade set up for a task is still standing, still complete and still where it was placed.
Missing, damaged or displaced barriers
Flags barriers knocked out of position or removed before the work they enclose has finished.
Barrier bypass and unsafe shortcuts
Detects people stepping over or around a barrier rather than walking the route it defines.
Missing signage and demarcation
Surfaces zones set up without the signage the procedure calls for.
Crane swing radius and lifting exclusion zones
Follows the zone as the crane slews, rather than treating it as a fixed polygon.
Excavation-zone barriers and edge proximity
Covers barriers, depth and equipment standing too close to an excavation edge.
Temporary electrical exclusion zones
Applies the same treatment to zones created for temporary electrical work.
Open holes, exposed edges and incomplete guardrails
Detects the conditions the construction paper names where a zone should exist and does not.
Cone, sign and barrier placement verification
Confirms that the setup matches the plan before the task starts.
Shifting fence lines and temporary boundaries
Adapts to perimeters that move as the site progresses, without a re-survey each time.
Where it applies
The sub-sectors below are the ones the Q3 industry papers name for this detection. Each links to the industry hub.
In Oil & Gas
Crane swing radius around live lifts on rigs, offshore platforms and refinery yards. Mobile-equipment exclusion zones during maintenance and turnarounds.
How it works
01
Runs on the cameras you already have
Inference happens at the edge on your existing CCTV and IP streams. No new camera estate, no video leaving site, no cloud round-trip in the detection loop.
02
Thresholds and zones you configure
Draw the zone, set the rule, set the dwell, count and confidence thresholds. Rules differ by area, shift and task, because sites do.
03
Evidence, not just alerts
Every event is logged with camera, zone, timestamp and a clip, so the record is reviewable afterwards and usable in a corrective action.
04
Integrates with what you already run
Events push into your VMS, alerting and reporting stack through Fogsphere Manager, with dashboards broken down by area, shift and crew.
Risk & control objective
The Q3 chemical paper frames the question the way a supervisor would — whether the barricade has actually been established — and the oil & gas paper describes perimeters that adapt to shifting fence lines and temporary barriers as work progresses. A fixed camera rule cannot follow that. A zone drawn once is wrong the day after the lift plan changes.
The control objective is zone integrity treated as a live state rather than a setup step: the zone exists, it is complete, it is in the right place, and it is still all three an hour later. What the operator gains is a record that a temporary control was in place for the duration of the task it was created for, which is normally the weakest evidence in a lifting or excavation file.
