Catch PPE and zone violations before they become incidents
Astra23 watches your site cameras for the safety failures that lead to injuries and insurance claims — the instant they happen, not in the post-incident review.
What it detects
Rules tuned for this environment
PPE detection
Helmets, high-vis vests, and harnesses — required per zone and flagged when missing.
Zone-breach detection
Restricted and active-work zones drawn on the feed; entries without authorization are flagged.
Machinery proximity
Unsafe closeness between workers and moving equipment triggers a caution or violation.
Who it's for
Built for site-safety officers and compliance
Give safety officers eyes on every camera at once, and give compliance and insurance teams a defensible, timestamped record.
- Site-safety officers get real-time alerts instead of chasing incidents after the fact.
- Insurance and compliance teams get an exportable log of every flagged event.
- Works on the cameras already installed across the site — no new hardware.
Worked example
A 'no harness at height' detection, end to end
Detect
A worker is identified on elevated scaffolding without a harness. Confidence is high; the rule for this zone requires fall protection.
Alert
Within seconds, the site-safety officer gets a push and WhatsApp alert with a timestamped clip framing the worker.
Logged
The event is recorded in the compliance dashboard, attributed to the zone and shift, and available for export.
