Business Objective: Improve worker productivity while strengthening on‑site safety compliance using existing surveillance infrastructure.
Manual Monitoring Couldn't Keep Pace
Construction and industrial sites often lack real‑time visibility into workforce productivity and safety. Manual monitoring methods are time‑consuming, inconsistent, and reactive, making it difficult to track worker activity, identify productivity bottlenecks, and ensure continuous PPE compliance. This results in operational inefficiencies, increased safety risks, and limited insight for data‑driven decision‑making.
"Supervisors were walking the floor for 4‑5 hours a day just to monitor activity. We had no data, no patterns, no accountability. Everything was reactive."
— Project Manager, Tier 1 Construction ClientTurning CCTV Into a Workforce Intelligence Platform
Alphaleo's VisionBenchAI leverages artificial intelligence and computer vision to transform standard CCTV infrastructure into a real‑time workforce intelligence platform. The solution continuously analyses worker movement, safety behaviour, and operational patterns to provide supervisors with actionable insights — without requiring additional hardware investments.
Worker Productivity Monitoring
Continuously monitors worker movement and activity to identify idle or unproductive periods using AI‑based pose and motion analysis. Tracks active working hours, idle duration, and productivity trends across workers, zones, and shifts.
Group Behaviour Analytics
Detects prolonged worker gatherings by identifying clusters of two or more individuals in non‑designated areas and evaluating duration and context. Distinguishes operational collaboration from non‑productive group activity.
PPE Compliance Monitoring
Performs real‑time detection of critical PPE — helmets, safety vests, gloves, goggles, boots, and face masks — for every worker on site. Instantly identifies violations and generates automated alerts with photographic evidence.
Intelligent Alerts & Workforce Insights
Delivers real‑time notifications for safety violations, idle workers, and unauthorized gatherings through configurable alert channels, plus interactive dashboards for productivity and compliance trends.
Six Categories of Protective Equipment, Detected Per Worker
VisionBenchAI detects six categories of personal protective equipment using multi‑label classification per worker bounding box, enabling granular compliance reporting at the individual level.

VisionBenchAI is built on a layered edge‑cloud architecture that processes video locally for latency‑critical inference while syncing structured event data to the cloud for analytics and reporting.
From Discovery to Full Handover in 60 Days
Discovery & Data Collection
Site walkthrough, camera placement audit, and manual annotation of 4,800+ images covering workers, PPE gear, and activity patterns under varied lighting and weather conditions.
Model Training & Validation
Fine‑tuned YOLOv8m on a site‑specific dataset with separate model heads for person detection, PPE classification, and activity state. Validated mAP@0.5 of 91.3% on the held‑out test set.
Edge Deployment & Integration
Deployed the inference pipeline on NVIDIA Jetson AGX Orin nodes, integrated with the existing 32‑camera CCTV setup via RTSP, and built an alert relay to supervisor WhatsApp and the web dashboard.
Live Operations & Tuning
30‑day shadow mode running alongside manual supervision. Model thresholds tuned based on false‑positive feedback, supervisor adoption training delivered, and full handover completed at Day 60.
Measurable Impact Within 60 Days
Reduction in worker idle time within 60 days of go‑live, driven by supervisor visibility and worker awareness of real‑time monitoring.
Reduction in PPE violation & non‑compliance incidents — from an average of 23 violations per shift pre‑deployment to fewer than 9, with zero hard‑hat violations in three months.
Reduction in supervisor monitoring effort and floor‑walk time; site managers shifted from reactive monitoring to proactive zone management using dashboard heatmaps.
ROI within 6 months, through productivity gains, reduced safety incidents, and labour efficiency improvement on a 180‑worker site.
