See what your cameras see. Act before it hurts.
Two detections that cover the violations behind most site injuries, delivered as alerts your team can act on in seconds.
PPE detection
Sentrywork checks hard hats and high-visibility vests per person, per frame, on every connected camera. When someone works unprotected for more than a moment, your team knows, with a clip, a camera ID, and a timestamp.
- Hard hat and hi-vis vest compliance, per person
- Zone-aware rules: stricter checks where the risk is higher
- Compliance trends per site, per week, per gate
Zone & proximity alerts
Draw exclusion zones on the camera view: a crane radius, an open trench, a vehicle route. Sentrywork tracks worker positions frame by frame and alerts the moment someone stays inside a zone they shouldn't be in.
- Zones drawn in minutes, directly on the camera view
- Alerts on sustained presence, not a single stray frame
- Blocked emergency exit detection on the roadmap
From first call to first alert.
Share your camera setup
Most standard IP cameras connect by stream URL. We review your layout with you and pick the feeds that matter most for safety.
Calibrate zones and rules
Together we draw exclusion zones and set the PPE rules per area: stricter at the crane, lighter in the car park.
Go live and tune
Alerts start flowing to the people you choose. Early confirmations and dismissals tune the models to your site.
What a safety manager actually sees.
In the morning. A one-page summary: overnight alerts, compliance rate per camera, anything still open.
During the day. Silence, unless a violation persists. Then a notification with the clip. Confirm it, assign it, or dismiss it; each choice is logged and each one teaches the model.
At the end of the week. Trends worth acting on: which gate keeps failing vest checks, which subcontractor's crew triggers the crane zone, which camera can't see what you assumed it could.
