High-Risk Zone & Restricted Area Monitoring

Description

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

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.

Activity

Maintaining continuous or regularly checked visual surveillance of restricted zones to detect unauthorised access, unsafe proximity, or exclusion boundary breach.

Conclusion

High-risk activity completed without safety incident. Any exclusion zone breach detected and acted on in real-time. Footage retained as compliance record.

Role detail

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.

Steps (10)

1. 1Pre-activity safety planning identifies zones requiring restricted access.
2. 2RAMS completed specifying monitoring requirement for the restricted zone.
3. 3Camera positions reviewed to confirm restricted zone coverage.
4. 4PTZ camera pre-programmed or manually positioned to cover exclusion zone.
5. 5Site safety manager/designated monitor opens the evidence system live view.
6. 6Live monitoring conducted for duration of high-risk activity.
7. 7If unauthorised person enters zone, work halted and individual directed out.
8. 8On completion of high-risk activity, zone stood down.
9. 9the evidence system recordings retained as safety compliance record.
10. 10In case of incident, footage immediately preserved and provided to investigating authority.

Evidence (3)

• “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.”

  Anonymized evidence record 42.1

• “Pre-activity safety planning integration with camera monitoring of excavation edges and live service corridors — establishing the zone coverage requirement before work commences.”

  Anonymized evidence record 42.2

• “The ability to remotely check work zones helped avoid multiple daily trips across the site.”

ROI model — Template G

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)

Notes

Product opportunity: automated breach detection replacing human monitoring. Critical constraint: camera coverage must be pre-validated before activity begins.
