Applications / Safety
Restricted Height
Detects people present on elevated structures and height-restricted levels — catwalks, monkey boards, mezzanines and roof areas — and flags access outside permit.

Access detection on height-restricted levels
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.
Catwalks and monkey boards
Flags presence on drill-floor monkey boards, process-unit catwalks and access gantries.
Elevated platforms and mezzanines
Detects people on maintenance platforms and mezzanine levels where access is controlled rather than open.
Roof and open-floor access
Covers roof access and floor openings, which the Q3 power-generation paper lists together as monitored conditions.
Access outside a permitted window
Surfaces entry to a height-restricted level when no permit or work window is recorded as active.
Platform occupancy above the limit
Counts people on an elevated platform and flags overcrowding against a configured maximum.
Elevated maintenance activity
Detects maintenance work in progress at height, which the Q3 papers track as a distinct zone state.
Personnel beneath elevated work
Flags anyone positioned under an active elevated area, alongside the line-of-fire rule.
Time at height per person and zone
Logs dwell so exposure at height is measurable rather than inferred from the permit record.
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
Drill floor monkey-board access on rigs and SOVs. Refinery elevated platforms and process-unit catwalks. Offshore platform deck monitoring for overhead hazards.
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
Height-restricted levels are controlled ground: access is granted through a permit or a work window, not by default. The control objective is knowing who is up there, when, and whether that matches what was authorised — a question a permit register answers on paper and a camera answers in real time.
The second half of the objective sits below rather than above. Elevated activity creates a dropped-object exposure for everyone underneath, which is why the Q3 papers list personnel beneath elevated work as its own monitored condition. Detection covers both sides of that relationship from the same camera view.
