I. Company Overview
  Shenzhen Fushitongda Technology Co., Ltd. (Fsmart) , established in June 2013, is a technology-focused enterprise integrating R&D, independent production, and global sales in the solar-powered smart security sector. The company operates an independent R&D and manufacturing base in Shenzhen. Its core products—the A20 and B20 series solar 4G surveillance cameras—are designed for off-grid outdoor scenarios including farms, construction sites, and rural courtyards.
  Fsmart maintains a R&D team of nearly 200 professionals, covering hardware structure design, embedded software development, solar power efficiency optimization, and 4G/WiFi communication adaptation. The manufacturing base features end-to-end independent production capacity from SMT placement and battery component processing to complete system assembly and testing. All critical processes are completed in-house, with an annual delivery capacity exceeding one million units.
  The factory implements a four-tier quality control system: Incoming Quality Control (IQC), In-Process Quality Control (IPQC), Final Quality Control (FQC), and Outgoing Quality Control (OQC). Every A20 and B20 series unit must pass multi-dimensional testing across waterproofing, endurance, RF, and functionality before shipment, with a dual quality standard of 100% automated inspection plus manual verification.
  In addition to the R&D team, the company has a global business team of nearly 20 members, all born in the 1990s and 2000s. Young, dynamic, and highly capable, they handle overseas market expansion, digital marketing, customer service, and channel support—serving as a vital force connecting the company to worldwide markets.

II. R&D Team: The Foundation of Product Reliability
  The nearly 200-member R&D team is Fsmart's technical core. The team performs deep customization for solar security scenarios: custom-developed BMS protection boards delivering triple hardware-level protection against overcharge, over-discharge, and over-temperature; independently designed 4G and WiFi dual antennas addressing co-channel interference through structural layout and frequency band avoidance; continuously optimized low-power algorithms balancing endurance and response speed; and independently designed waterproof sealing structures with dedicated optimization for long-term outdoor reliability.
  The R&D team's work spans the entire product lifecycle—from concept definition and prototype development to testing validation and mass production introduction—ensuring every A20 and B20 series unit undergoes complete reliability validation before leaving the factory.

III. Global Business Team: Young, Dynamic, and Connected
  Fsmart's global business team is composed of nearly 20 young professionals born in the 1990s and 2000s——a vibrant and highly capable group. They are innovative, proactive, and skilled at leveraging digital tools to expand overseas markets. Their work covers overseas customer development, independent website development and operations, social media marketing, product design support, and offline distributor relations. Facing diverse global market demands, they respond quickly and collaborate efficiently, serving security integrators, distributors, and brand customers worldwide with multilingual communication skills and cross-cultural experience.

  Young yet experienced, they combine solid practical capabilities with keen industry insight——a vital bridge between the factory and international markets, and a core driving force behind Fsmart's continuous global expansion.

IV. Team Collaboration: From Factory to Global Customers
  The nearly 20-member global business team works in close coordination with the nearly 200-member R&D team and the full-chain manufacturing base, forming a complete closed loop from product definition and manufacturing to global sales and service. The customer development team captures demand, the product design team provides customization solutions, the website and social media teams build online trust, and the distributor team delivers localized service—every stage relies on the manufacturing capability and quality control system of the company's own factory.
  Fsmart A20 and B20 series solar 4G surveillance cameras are manufactured end-to-end at the Shenzhen base, from SMT placement to finished product shipment. The young global business team then brings these products across borders to serve security integrators, distributors, and end users worldwide.
