Smart Site Safety System (4S)

IoT, AI video analytics and a cloud platform brought together: smart watches, beacons, gas detectors, CCTV and every other sensor on site feed one dashboard, moving safety management from reacting to preventing.

Centralised Management Platform (CMP)

The digital brain of the whole site safety system. It aggregates data from every device and sensor and shows worker locations, equipment status and environmental conditions in real time, so supervisors analyse trends, generate compliance reports and handle emergencies from one dashboard.

Seven modules at a glance

Centralised Management Platform (CMP)

The digital brain of the whole site safety system. It aggregates data from every device and sensor and shows worker locations, equipment status and environmental conditions in real time, so supervisors analyse trends, generate compliance reports and handle emergencies from one dashboard.

Digitised Tracking System

Smart wearables, Bluetooth beacons and GPS track the real-time location of personnel, vehicles and high-value assets across the site. With digital zones and geofences, supervisors are alerted automatically when a worker enters an unauthorised area or an asset leaves its boundary.

Electronic Permit to Work (PTW)

Workers and supervisors use phones or tablets to manage electronic permits for high-risk work such as hot work, working at height and excavation. A checklist of safety controls, risk assessments and isolation procedures must be verified and signed off before work starts, and every permit leaves an auditable record.

Hazardous Area Access Control

Smart electronic locks, turnstiles or digital authorisation tied to a worker's ID control access to substations, chemical stores, deep excavations and other dangerous zones. Every entry and exit is logged, so only authorised, trained and medically fit personnel get in.

Unsafe act / dangerous situation alerts

AI cameras use computer vision to detect missing personal protective equipment (PPE), falls from height or unauthorised entry automatically, without anyone watching screens, and alert supervisors immediately.

Confined space monitoring

Wireless sensors continuously monitor gas levels (toxic, flammable or oxygen-deficient), temperature and humidity inside confined spaces, while wearables track worker presence and vital signs. When conditions become hazardous or no movement is detected, the platform raises an alarm to start rescue.

Integrated live CCTV

High-definition video from multiple cameras streams live into the CMP for verifying incidents and safety alerts, managing site logistics, deterring theft and making decisions during an emergency.

Equipment

Site safety equipment

Every device connects to the Centralised Management Platform and can be combined to suit the site.

  • Smart Watch

    Smart Watch

    Heartbeat, fall detection, location monitoring, SOS button and heat-stress warning.

  • Bluetooth Beacon

    Bluetooth Beacon

    Low-power positioning device for indoor and outdoor use: mobile danger-zone detection and personnel/asset location.

  • Gas Detector

    Gas Detector

    Monitors oxygen, carbon dioxide, hydrogen sulphide and methane levels with real-time alerts.

  • Electronic Smart Lock

    Electronic Smart Lock

    The CMP generates the unlock code; works with the e-permit system to control hazardous-area access and can be GPS-located.

  • AI Camera

    AI Camera

    PPE detection, security surveillance, danger-zone alerts and live checks on job status.

  • Warning Signal Lamp

    Warning Signal Lamp

    Built-in LED and buzzer; triggers from any sensor to warn people on site.

  • Water Detector

    Water Detector

    For basements and low-lying areas; alerts when the water level exceeds the set threshold.

  • Temperature Detector

    Temperature Detector

    Detects overheating in motors, pumps and similar equipment; alerts above the set temperature.

  • Smart Button

    Smart Button

    Single, double and long press can each trigger a custom action: call for help or start a scene.

  • Noise Sensor

    Noise Sensor

    Records sound pressure, equivalent continuous level and maximum; alerts when the limit is exceeded.

  • Multifunctional Ultrasonic Distance Sensor

    Multifunctional Ultrasonic Distance Sensor

    Three preset modes (standard, rubbish bin, parking) for distance and fill-level detection.

  • X5 Sensing Camera

    X5 Sensing Camera

    Outdoor camera with timed snapshots for tides and site progress; low power, optional solar panel.

  • X1 Sensing Camera

    X1 Sensing Camera

    Infrared supplementary light for clear images in the dark.

  • Parking Sensor

    Parking Sensor

    Detects whether a bay or loading area is occupied, with occupancy/vacancy alerts.

  • People Counter

    People Counter

    Counts people entering and leaving with up to 98% accuracy; privacy-protection mode available.

  • Door / Window Detector

    Door / Window Detector

    Real-time open/closed status with alerts on either state.
