At the bustling Qinghu Agricultural Market in Longhua District, Shenzhen, daily foot traffic is heavy, posing significant challenges to safety and management. To address issues such as difficult traditional surveillance cabling, incomplete network coverage, and complex operations and maintenance, the market management has implemented Guangwangshi’s cost-effective PoE networking and fiber-optic extension solution. With a streamlined and reliable network architecture, this solution lays a solid digital foundation for enhanced market security and intelligent management.
Project Challenges: Balancing Complex Environments with Cost Control
As an important community hub for residents’ daily needs, the Qinghu Agricultural Market requires a network infrastructure that addresses practical concerns within a limited budget:
Complex Cabling Environment: The market features densely packed stalls, making it challenging to install conventional surveillance systems that require separate power and network cables. This not only complicates installation but also compromises the aesthetic appeal of the space.
Long-Distance Coverage Requirements: The market spans a large area, with certain zones beyond the reach of standard Ethernet cables. A stable, long-distance transmission solution is essential.
Simple Operations and Maintenance: Lacking dedicated IT personnel, the management demands network equipment that is stable, easy to use, and virtually maintenance-free.
High Cost-Effectiveness: While ensuring core surveillance and network requirements are met, the overall project cost must remain tightly controlled.
Guangwangshi Solution:
A Minimalist Network Featuring PoE Power Delivery and Fiber Optic Extension
Addressing the unique characteristics of the market, Guangwangshi has designed an integrated networking solution centered around standard PoE power delivery and extended connectivity via fiber optic transceivers.
Core Access Layer: Standard PoE—One Cable Does It All
Multiple Guangwangshi standard PoE switches have been deployed at the market’s monitoring center and in distribution boxes across various areas.
Each device provides 16 100 Mbps PoE ports and 2 Gigabit uplink ports. The PoE ports fully comply with IEEE 802.3af/at standards, automatically detecting and safely powering compliant devices such as IP cameras and wireless APs.
“Dual-Purpose” Connectivity: A single network cable simultaneously carries both data and power to front-end devices, greatly simplifying camera installation above stalls and passageways. This eliminates the need for disruptive trenching and wiring, enabling rapid and flexible deployment.
Automatic Watchdog Restart Ensures Truly Zero-Touch Operations
Remote Extension Layer: Fiber Optic Transceivers Break Distance Barriers
For surveillance points located far from the core switch, Guangwangshi’s single-mode dual-fiber optical transceivers provide seamless connectivity.
These devices efficiently convert twisted-pair electrical signals into fiber-optic signals, effortlessly extending network reach from copper-based hundred-meter limits to tens of kilometers, perfectly covering remote locations throughout the market and surrounding areas.
The equipment is plug-and-play, requiring no complicated configuration, while offering robust link diagnostics to ensure clear, smooth video streams over long distances.
Key Features and Value of the Solution
Streamlined Deployment, Controllable Costs: PoE technology significantly reduces installation complexity and overall cabling expenses; fiber optic transceivers solve long-distance transmission challenges at a lower cost, resulting in an exceptionally cost-effective solution.
Stable and Reliable, Simplifying Management: All devices utilize mature commercial-grade architectures, offering plug-and-play functionality without specialized configuration. Switches feature comprehensive power protection, while transceiver link status is readily visible, ensuring stable system operation and substantially easing the day-to-day maintenance burden on management teams.
Clean Architecture, Flexible Expansion: The standardized network design leaves ample room for future additions—such as more security cameras, upgraded wireless coverage, or smart weighing systems—ensuring the longevity of the market’s IT investments.
Enhanced Security, Improved User Experience: Full‑coverage, blind-spot‑free video surveillance elevates security management standards, while a stable network delivers superior wireless connectivity for merchants and customers alike.
Project Outcomes
Following implementation, the Qinghu Agricultural Market swiftly established a comprehensive, crystal-clear, and reliably operating security surveillance network. Managers can now monitor the entire premises from the command center, significantly strengthening operational order and safety measures. Since going live, the entire network has remained stable and uninterrupted, earning unanimous praise from both management and vendors.
The head of the market management office commented: “Our market environment is quite unique, and traditional surveillance installations involving power and cabling were extremely cumbersome. Guangwangshi’s solution resolved both power supply and connectivity issues with just one cable, enabling lightning-fast installation and eliminating post‑deployment problems. Video quality remains consistently crisp, delivering real peace of mind, cost savings, and excellent results.”
