Applications / Safety
Work at Height
Detects harness and lanyard use, ladder and scaffold behaviour, and proximity to unprotected edges wherever work is carried out above ground level.

Harness, ladder and edge detection at height
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.
Harness presence and lanyard attachment
Flags a harness worn without the lanyard clipped, where the anchor point is visible in frame.
Unsafe ladder use
Detects poor angle, unstable footing, over-reaching and standing on the top step.
Scaffold access and incomplete scaffold
Surfaces access to scaffold that is incomplete or untagged, listed in the Q3 chemical and manufacturing papers.
Proximity to unprotected edges
Flags people close to open edges and floor penetrations, named across the Q3 chemical, manufacturing and automotive papers.
Missing or incomplete guardrails
Detects open holes, exposed edges and missing edge protection as a site-condition signal.
Mezzanines, platforms and roofs
Covers elevated work areas, which the Q3 automotive paper lists together as the work-at-height zone set.
Platform overcrowding
Counts people on an elevated platform against a configured limit.
Personnel beneath elevated activity
Flags anyone positioned under active work at height, alongside the line-of-fire rule.
Dropped-object exposure
Detects materials and tools at edges that create an exposure for the level below.
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
Derrick and scaffolding edges on drilling rigs. Offshore platform deck work and elevated maintenance. Refinery elevated walkways and overhead structures. Construction work at edges and open holes.
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
Falls from height remain the largest single fatality category in construction and among the largest in heavy industry, and the controls are well understood: harness and anchor, edge protection, tagged scaffold, correct ladder use. The gap is never the control — it is knowing whether it was in place during the hours nobody was watching.
The Q3 construction paper adds a second dimension that periodic inspection cannot supply: daily or weekly progress evidence with timestamps, and harness-compliance data captured as work proceeds. That turns work at height from a series of inspection snapshots into a continuous record, and gives the operator the leading indicators — unprotected edges, untagged scaffold, missing guardrails — while they are still conditions rather than events.
