How VERSA solves key pain points
High accident and injury rates on construction sites in Hong Kong.
AI cameras, danger zone monitoring, and real-time alerts help prevent incidents instead of just recording them for later review.
Slow or missed response to hazards due to manual monitoring.
Real-time notifications via dashboard, SMS and alarms mean safety teams can intervene within seconds, not minutes.
Heavy compliance workload and evolving safety regulations.
Automated logs, video archives, PTW records and access histories simplify reporting and audits for Labour Department and client checks.
Built to fit the Smart Site Safety System (4S) framework, including AI cameras, smart devices, and a centralized management platform for data consolidation.
Designed to support contractors working on capital works over HK$30 million, where adoption of 4S-aligned smart safety systems is mandatory.
Supports CITF-aligned components such as AI cameras for danger zones, worker positioning, gas monitoring and CMP, helping projects benefit from available subsidies.
Automated logs, reports and video records make it easier to demonstrate compliance with the Labour Department, DEVB 4S mandates and client requirements.
Aligned with Hong Kong’s smart site safety direction.
