Stop the fall before it starts.
Construction kills more workers than any other industry, and most of it happens at height or in the path of plant. Invigilo watches every camera on your site for the precursors: an unclipped harness near an edge, a missing barricade, a crew inside a crane radius. Alerts reach the supervisor while the hazard is still a near miss.
What actually hurts people in construction
Sites with rotating contractor crews cannot rely on everyone knowing the rules. The risks below sit on camera long before they become incidents, and they are exactly what the detection layer is tuned for.
Detections tuned for construction
SafeKey runs these detections on your existing site cameras, tuned per zone and per phase of work. When a rule is broken, the alert reaches the responsible supervisor in under a second.
Measured at a live public housing project
HDB Singapore deployed Invigilo across an active construction site on existing cameras. The outcomes below were measured on the site itself.
No new cameras. No new workflow.
Your existing CCTV
Any camera with an RTSP stream connects. No new hardware for standard deployments.
Edge processing
AI runs on site. Footage stays local, and detection keeps running if the uplink drops.
Alerts where you work
WhatsApp, Microsoft Teams and email, in under a second, with your escalation chain.
Live in 24hr
A standard site is operational within 24 hours of camera access.
Where else Invigilo runs
Construction, answered
Does it work with the cameras we already have?
Yes. SafeKey connects to existing RTSP and ONVIF cameras. Most sites need no new hardware.
How long does deployment take?
From camera access to live detection is typically 24 hours.
Does it work without an internet connection?
Yes. Processing runs on site through edge or on-premise deployment. Video does not need to leave the site.
What happens after a detection?
An alert reaches the team through WhatsApp, Microsoft Teams or email within seconds, with the video evidence attached.
Can it detect a fall risk before someone falls?
It detects workers near unprotected edges, open penetrations and missing barricades in real time, so the alert arrives while the exposure is still preventable.
