Construction Site Site Compliance

LinkerVision turns a construction site's existing camera network into a 24/7 VLM-based site-compliance system. On live feeds it checks that workers wear the required PPE such as hard hat, hi-vis, harness, and boots in designated zones, detects people entering restricted or dangerous zones such as exclusion zones, active lifts, and the after-hours site, and flags people lingering in sensitive areas such as equipment stores, material laydown, and the site boundary for review.

VLM output

An elevated wide shot of a large open concrete deck on an active construction site, where dozens of workers in high-visibility vests and hard hats move about, kneel at work positions, and handle formwork panels and rebar near stacked materials, a towing compressor, and pink barriers. Over the four frames small groups of workers walk across the deck and cluster around the formwork area on the left while the rest of the scene stays largely unchanged.

Customer challenges

1

PPE non-compliance drives injuries and citations, and manual checks can't cover a large, changing site; open sites are hard to secure, so intrusion and entry into danger zones risk injury, theft, and liability; and loitering can signal theft or trespass but can't be tracked manually across a large site.

Customer benefits

More consistent safety compliance, reduced unauthorized access, improved security, and lower operational and liability risk.

Key features

PPE Detection

Checks whether workers wear the required protective equipment.

Unauthorized Access Detection

Detects entry into restricted or closed site areas.

Loitering & Dwelling

Before & after

Before PPE compliance, restricted zones, and suspicious activity depend on periodic inspections and manual security patrols. After — with Linker AI Nexa AI continuously checks compliance and site activity, automatically flagging PPE violations, unauthorized access, and suspicious dwelling.
