High-Risk Zone & Restricted Area Monitoring
the evidence system fixed and PTZ cameras positioned to provide continuous surveillance of designated high-risk zones, replacing the need for a dedicated human watcher/spotter.

Trigger, activity, conclusion
High-risk activity planned/ongoing — crane operations with exclusion zones, deep excavation with collapse risk, proximity to live buried services, or work near energised electrical infrastructure.
Maintaining continuous or regularly checked visual surveillance of restricted zones to detect unauthorised access, unsafe proximity, or exclusion boundary breach.
High-risk activity completed without safety incident. Any exclusion zone breach detected and acted on in real-time. Footage retained as compliance record.
Workflow steps
- Step 01
Pre-activity safety planning identifies zones requiring restricted access.
Inferred - Step 02
RAMS completed specifying monitoring requirement for the restricted zone.
Inferred - Step 03
Camera positions reviewed to confirm restricted zone coverage.
Evidenced - Step 04
PTZ camera pre-programmed or manually positioned to cover exclusion zone.
Inferred - Step 05
Site safety manager/designated monitor opens the evidence system live view.
Evidenced - Step 06
Live monitoring conducted for duration of high-risk activity.
Evidenced - Step 07
If unauthorised person enters zone, work halted and individual directed out.
Inferred - Step 08
On completion of high-risk activity, zone stood down.
Inferred - Step 09
the evidence system recordings retained as safety compliance record.
Evidenced - Step 10
In case of incident, footage immediately preserved and provided to investigating authority.
Evidenced
Evidence records
Monitoring of crane exclusion zones and areas where only authorised personnel should be present — continuous surveillance replacing the need for a physical watcher during lift operations.
Pre-activity safety planning integration with camera monitoring of excavation edges and live service corridors — establishing the zone coverage requirement before work commences.
The ability to remotely check work zones helped avoid multiple daily trips across the site.
ROI model
risk reduction
Low-probability, high-consequence events whose expected cost is reduced by Evercam's monitoring, deterrence, or evidence capability. Calculated as expected value (probability × cost). Presented separately from operational savings in the output document under 'Risk Mitigation Value'.
annual_risk_without = event_probability × event_cost; annual_risk_with = (event_probability × (1 - probability_reduction_pct)) × (event_cost × (1 - cost_mitigation_pct)); saving = (annual_risk_without - annual_risk_with) × (project_duration_months / 12)
