Smart Site Safety System
One platform for total site safety.
SSSS unifies people, plant and environment across your construction sites — turning sensors, cameras and wearables into real-time alerts, digital permits and live oversight.
- Deployed on real Hong Kong contractor sites
- Many sites, one centralised backend
- Trilingual interface (繁 / 簡 / EN)
- Built for regulated high-risk work
Three pillars
People 人
Protect every worker on site. Smartwatches and body sensors catch SOS calls, falls, abnormal heart-rate and lone-worker risk, while AI cameras verify that helmets, vests and masks are worn in the zones that matter.
Plant 機
Keep workers clear of moving machinery. Proximity warning alerts crews near operating plant over a per-site secured channel, reducing struck-by risk around moving plant.
Environment 環境
Watch the air your team breathes. Continuous gas and environmental monitoring tracks O2, CO, H2S, explosive gases, airflow and water with two-level warning and danger thresholds — essential for confined-space and toxic-gas work.
Feature highlights
Everything a safe site needs, on one platform.
AI Cameras
Turn existing Dahua IP cameras into PPE checkpoints, with helmet/vest/mask detection in defined zones, an RTSP-over-WebSocket live player and a 2×2 / 1×2 monitoring wall.
Site Visualisation & Positioning
Locate people and assets at a glance on a territory-wide 3D map with building extrusion, indoor floor-plan markers and BLE positioning that shows who and what is on site right now.
Confined-Space & Toxic-Gas Monitoring
Run high-risk work with confidence using a real-time multi-gas dashboard (O2 / CO / H2S / explosive / temperature / humidity / water / airflow), historical time-series and configurable warning and danger thresholds.
Digital Permit-to-Work
Replace paper permits with template-driven electronic permits — multi-step approval, on-screen digital signatures, authorisation-group countersign and a printable PDF for site posting, all with a full audit trail.
Live Alert Centre
See every safety event the moment it happens — blinking rows, an audible alarm and a push to phones within seconds — then acknowledge, remark and run drills with built-in alert simulation.
IoT Wearables
Give every worker a safety lifeline — heart-rate smartwatches detect falls, abnormal vitals, inactivity and low battery, and trigger an SOS at the press of a button. Bulk CSV provisioning gets a whole crew online fast.
Patrol & Attendance
Verify guard tours and attendance automatically with BLE-beacon check-in and mobile photo sign-in/out, with travel-time windows that flag skipped (too fast) or late (too slow) points.
How it works
- 1
Detect 偵測
Cameras, gas and environmental sensors, wearables and gateways continuously collect site data.
- 2
Analyse 分析
The rule engine and AI evaluate thresholds, PPE compliance and worker biometrics in real time.
- 3
Act 行動
Instant alerts reach phones, the alert centre and on-site alarms; rules trigger automatic controls such as cutting power, with live dashboards and scheduled reports for the record.
Why SSSS
One platform, three domains.
Unify people, plant and environment in a single system — replacing several disconnected tools and paper workflows.
Built for many sites.
A main contractor manages multiple sites and contracts from one centralised, multi-tenant backend.
Hardware-neutral.
Open integration with Dahua cameras, BLE and WiFi sensors, heart-rate smartwatches, TP-Link smart-plugs, HHDlink e-locks and IR air-con — no single-vendor lock-in.
Real-time by design.
The rule engine and push delivery move data from sensor to phone within seconds.
Localised for Hong Kong.
Trilingual interface, HK timezone and a compliance-oriented design for regulated confined-space, working-at-height, hot-work and lone-work activities.
Proven in the field.
Already deployed on real Hong Kong contractor sites (reference available on request).
