Smart Helmet Camera for Construction Sites

Construction safety teams were struggling to understand what was really happening across large, multi-level sites in real time. They had no easy way to monitor whether workers were consistently wearing helmets and vests, entering restricted or hazardous areas, or facing unsafe conditions, often realising problems only after reviewing CCTV footage once an incident had already occurred.

Workers in high risk zones had no simple way to alert supervisors, share what they were seeing during emergencies, or capture video directly from their own point of view, creating a clear need for a smarter, worker-centric safety solution.

An Android SOM with an ARM processor and onboard GPU was built directly into the helmet, handling all video processing and AI inference on the device. A wide-angle camera integrated into the helmet visor captured the worker's point-of-view video feed continuously throughout the shift.

A high-sensitivity GNSS receiver tracked each worker's real-time location on a live site map, while a 4G LTE modem handled video streaming and alert transmission across the construction site.

An on-device PPE detection model continuously analyzed the video feed to verify helmet and safety vest compliance, automatically flagging any violations without manual supervision.

All data was consolidated into a web-based site dashboard, giving supervisors a live worker location map, real-time video feed, and alert inbox in one place. Workers could also trigger an SOS alert directly from the helmet, instantly notifying the operations team with their live location and video feed.
