Every camera, a safety officer.
Sentrywork watches your existing site cameras and flags hazards the moment they happen, so your team acts before someone gets hurt.
Building with input from site operators and safety teams.
We build real-time vision systems so hazards get caught before they become incidents.
Almost every serious site already has cameras. What it doesn't have is someone watching every feed, every minute of the day. Sentrywork closes that gap: our models watch the footage continuously, and your team only hears about it when something needs a human.
About Sentrywork
From camera feed to clear alert.
Connect your cameras
Point your existing IP camera feeds at Sentrywork. No rip-and-replace, no new wiring in most cases.
Set your zones and rules
Draw exclusion zones around cranes, trenches, and traffic routes. Choose which PPE rules apply where.
Get instant alerts
When a violation persists, you get a notification with a clip and a timestamp. Evidence, not guesswork.
No new hardware
In most cases Sentrywork runs on the cameras you already own. Edge devices are available for low-bandwidth sites.
Works with your system
Standard IP camera streams connect directly. Your footage stays yours, handled under your retention rules.
One dashboard, every site
Compliance and alert history roll up across projects, so you can compare sites and act on the pattern, not the anecdote.
PPE detection
Hard hats and high-visibility vests, checked per person, per frame, across every connected camera at once.
Learn moreZone & proximity alerts
Draw an exclusion zone around a crane, a trench, or a traffic route. Know the moment anyone steps inside it.
Learn moreInstant alerts
A violation on camera becomes a notification in your pocket, with the clip attached. Not a vague "check zone B".

An auditable record
Every alert is logged with a clip, a camera ID, and a timestamp. A clean trail for compliance reviews, toolbox talks, and insurance conversations, kept under your retention policy.
Vision models built for real job sites, not lab conditions.
Live frames from your existing cameras
Standard IP camera streams, in the conditions real sites produce: dust, rain, glare, low winter light, and cluttered backgrounds.
The violations that cause injuries
PPE compliance per person, per frame. Workers inside exclusion zones near cranes, trenches, and heavy equipment. Blocked emergency exits.
Sustained violations, not single frames
Computer vision models classify PPE and track proximity in real time. An alert fires only when a violation persists past a set threshold. That is how we avoid false alarms from one odd frame.
Every decision feeds the model
Confirmed and dismissed alerts retrain and sharpen the models for each site's specific cameras, angles, and conditions.
Straight answers.
No. It extends their reach across every camera at once. Sentrywork surfaces what a human should look at. The judgement, the conversation, and the fix stay with your team.
Most sites can connect their existing IP cameras. For sites with limited bandwidth, we are building a path to on-site edge devices so detection runs locally without streaming raw video off site.
Within seconds of a sustained violation. Alerts fire on persistence, not on a single frame. That threshold is what keeps false alarms down and trust in the alerts up.
Only clips tied to alerts are stored, under your retention settings. We do not keep continuous recordings, and your footage is never used outside your account without your agreement.
Construction sites, warehouses, and heavy industrial facilities: anywhere cameras already exist and the cost of a missed hazard is measured in injuries, downtime, and premiums.
Our models are trained on footage from real sites: dust, rain, glare, and low light included. Where a camera genuinely can't see, Sentrywork tells you that too, rather than pretending to coverage it doesn't have.
[...] We are finalising the pilot process with our first site operators and will publish the details here.
