Information Technology (IT) Infrastructure is a collection of components such as hardware, software, networks, storage devices, and other essential resources that form the foundation for an organization to implement, operate, and maintain IT services. IT infrastructure includes servers, workstations, networking equipment, databases, cloud services, and security solutions, which enable businesses to transmit data, run applications, manage information, and ensure network security.

A Video Conference System is a digital communication solution that enables individuals or groups to hold face-to-face meetings in real-time, regardless of their physical location. Utilizing audio, video, and often screen-sharing capabilities, it allows seamless collaboration between remote participants.

These systems are commonly used in business, education, healthcare, and government sectors for virtual meetings, online training sessions, remote interviews, and team collaboration. Features typically include high-definition video and audio, participant management, chat, file sharing, virtual whiteboards, and integration with calendar and productivity tools.

Modern video conferencing systems may be hardware-based (dedicated conference room equipment) or software-based (platforms like Zoom, Microsoft Teams, Google Meet, etc.), and often support cross-device compatibility including desktops, laptops, tablets, and smartphones.

A Handheld Thermal Camera is a device that captures images based on infrared radiation, allowing users to observe and measure the temperature of objects in low-light or harsh environments. This device has a compact design, is easy to operate with one or two hands, and integrates a screen that visually displays measurement results and thermal images with colors corresponding to different temperature levels.

A Fixed Thermal Camera is a type of infrared camera permanently installed at a specific location to monitor and measure the temperature of objects, often moving objects like people or industrial processes. This device uses an infrared sensor to generate a thermal image (thermogram), displaying temperature differences using colors, which helps detect abnormal signs that are invisible to the naked eye.

A Handheld PD Testing Device (portable Partial Discharge detector) is a compact, mobile tool used to detect and assess the insulation condition of medium and high-voltage electrical systems by measuring Partial Discharge (PD)—a sign of insulation degradation before failure occurs. This device uses various types of sensors such as TEV (Transient Earth Voltage), UHF (Ultra High Frequency), and ultrasonic to collect signals, enabling quick diagnosis without needing to shut down the equipment.

Hệ thống Thiết bị Giám sát và Kiểm tra là tập hợp các thiết bị, cảm biến và công nghệ được sử dụng để thu thập dữ liệu, theo dõi, đo lường và báo cáo các hoạt động, sự kiện hoặc điều kiện trong một môi trường cụ thể nhằm đảm bảo an ninh, hiệu quả vận hành hoặc kiểm soát quy trình.

Các hệ thống này được ứng dụng rộng rãi trong nhiều lĩnh vực như an ninh (CCTV), sản xuất công nghiệp (SCADA), giao thông vận tải, y tế và môi trường.

National Defense and Security Equipment Systems are a collection of advanced tools, hardware, software, and technologies used to prevent, detect, deter, and respond to threats, protecting national security, critical assets, and personnel. These systems range from specialized operational equipment like unmanned aerial vehicles (UAVs) and autonomous underwater vehicles (AUVs), to cybersecurity solutions such as Intrusion Prevention Systems (IPS), as well as personal protective equipment.

Specialized Displays (or Professional Displays) are digital devices specifically designed for commercial, enterprise, and specific needs, featuring the capability for 24/7 continuous operation, high durability, and superior features compared to ordinary TVs, such as remote content management, screen partitioning, or high color accuracy for graphics. They are widely used in retail, advertising, healthcare, education, control centers, and even in industries requiring high endurance, such as manufacturing.
