Our Services
Smart Site Safety System (4S) – In active response to the latest initiatives rolled out by the Development Bureau and the Construction Industry Council (CIC), we have developed our proprietary Smart Site Safety System (4S) software platform. Driven by a SaaS model, this platform seamlessly integrates advanced IoT and AI Video Analytics technologies, unifying various on-site IP cameras and IoT sensors into a centralized system.


AI & Non-AI Video Monitoring for Confined Spaces – Utilizing advanced AI vision technologies, the system delivers real-time detection of worker behavior, environmental anomalies, and non-compliance with Personal Protective Equipment (PPE), triggering instant alerts for immediate hazard prevention. To assist contractors in meeting statutory record-keeping mandates, we also provide robust cloud recording capabilities that ensure securely backed-up video retention for up to one full year
AI Video Analytics Solutions – In real-world applications, our AI Video Analytics solutions are classified into four core categories, each leveraging diverse algorithms to automatically interpret video content and address complex monitoring needs through automated triggers or statistical insights:
- SOP Compliance Monitoring: The fastest-growing segment in recent years across both industrial and service sectors, ensuring operations strictly adhere to standardized procedures.
- Security & Perimeter Management: Advanced intrusion detection and continuous monitoring to safeguard site boundaries.
- Smart Recognition: Intelligent identification of specific objects, license plates, materials, or predefined attributes.
- Crowd Analytics: Data-driven tracking of crowd density, movement patterns, and flow distribution.


CIC CWRS Facial Recognition & Mobile Site Attendance Solutions – We offer a comprehensive suite of facial recognition terminals, card-swiping systems, handheld devices, and specialized software engineered to manage daily site attendance while fulfilling stringent project tender requirements. Attendance data can be uploaded directly to the Construction Industry Council’s (CIC) Construction Workers Registration System (CWRS). Furthermore, our proprietary cloud-based attendance software synchronizes records in real time, granting Main Contractors and subcontractors instant access to workers’ attendance logs.
Advanced AIoT & IoT Infrastructure – By leveraging cutting-edge communication technologies such as LTE, 5G, and LoRaWAN, we build a stable, robust wireless network that ensures site-wide coverage. This infrastructure enables the seamless interconnection of diverse smart sensors and intelligent devices. Through real-time data acquisition, advanced analytics, and automated system linkage, our platform empowers clients with the full convenience and strategic advantages of the Internet of Things (IoT).


Next-Gen Location-Based Services (UWB & BLE) – By leveraging Ultra-Wideband (UWB) and Bluetooth Low Energy (BLE) technologies, our solutions achieve flexible positioning tracking with millimeter-level to meter-level accuracy. The system automatically records personnel locations, distributions, and dwell times across different zones 24/7. This enables us to help clients build tailor-made solutions across all industries, significantly improving management quality and operational oversight.
VSaaS Cloud Recording Services – Breaking free from the limitations of traditional on-premise storage, our VSaaS seamlessly migrates your surveillance recording infrastructure to the cloud. This advanced solution empowers enterprise and institutional clients to drastically reduce hardware procurement costs and ongoing IT maintenance overheads. With the flexibility to scale storage duration and capacity on demand, management can achieve real-time, cross-regional remote inspections via a single centralized platform. Furthermore, backed by end-to-end encryption technologies, our service ensures bank-grade safety, protection, and bulletproof backup mechanisms for your video data—making surveillance management remarkably simple, secure, and highly efficient.
