When every second counts for life and safety, the stability of a hospital’s security network is the line between life and death. Faced with challenges such as outdated systems and blind spots in monitoring point maintenance at a Grade III hospital in Shantou, Guangwangshi restructured the hospital’s neural network using a PoE‑enabled intelligent three‑tier architecture, creating an intelligent security system.
Challenges in Medical Settings
Extremely high requirements for business continuity: Emergency and ICU areas operating 24/7 demand absolutely stable video transmission.
Complex terminal power supply: Hundreds of cameras and alarm devices require safe, centralized power delivery.
Difficult operations and maintenance: Traditional solutions are aging, suffer from long latency, and provide delayed feedback.
Solution:
Guangwangshi’s Intelligent Three‑Tier Network Architecture
The project employs Guangwangshi’s intelligent three‑tier network architecture to deliver a “zero‑perception upgrade” for the hospital’s security system.
Core Layer: Ten‑Gigabit Fiber Backbone
A three‑layer ten‑gigabit core switch is deployed, equipped with 16 gigabit optical ports, 8 combo ports, and 4 ten‑gigabit uplink ports.
Millisecond‑level self‑healing ring technology (ERPS protocol) is enabled, ensuring primary‑backup link switching in less than 20 ms.
Support for IPv4/IPv6 dual stack and dynamic routing creates a dedicated “fast lane” for medical data.
Aggregation Layer: Intelligent Service Scheduling
A redundant ring network is built using 24 electrical ports and 4 optical ports on gigabit managed switches.
MSTP multi‑instance protection isolates faults, so a single point of failure does not affect the entire hospital’s surveillance system.
ACL security policies precisely manage video stream priorities, guaranteeing zero bandwidth contention in emergency areas.
Access Layer: Integrated Power and Transmission
Large‑scale deployment of eight full‑gigabit PoE switches innovatively achieves:
Power delivery over 150 meters, solving wiring challenges in older hospital buildings.
Intelligent power allocation: With a total power capacity of 130 W per unit, fully meeting device power needs.
Zero‑configuration deployment: Plug‑and‑play automatic recognition of over 300 IPC devices.
Intelligent Operations Center
ONV centralized management platform provides visualized topology management of all devices across the hospital and automatically locates offline cameras.
Mobile alert integration: Real‑time notifications for power distribution anomalies or fiber optic interruptions boost operational response efficiency by 90%.
Key Advantages:
Scenario‑specific design: Enhanced moisture resistance, anti‑static properties, wide temperature tolerance, and support for multiple concurrent services tailored to medical environments.
Protocol‑level reliability: Industrial‑grade redundancy standards of less than 20 ms applied to commercial equipment.
Smart network management matrix: Multi‑dimensional control via web, app, and cloud lowers technical barriers.
Project Highlights
Revolutionized Operations Efficiency
Visualized status of all network devices reduces fault localization time from hours to within 90 seconds.
Remote configuration saves over 400 man‑hours annually in on‑site maintenance.
Enhanced Business Reliability
The system has operated continuously and stably for 18 months without major failures.
Under extreme weather conditions, packet loss rates in outdoor areas have dropped by 98%.
Unleashed Scalability
Ten‑gigabit optical port bandwidth reserves support future AI‑based behavior analysis, smart patient guidance, and other emerging applications.
PoE power port redundancy meets the demands of ward expansion.
User Feedback:
“The most noticeable improvement after the upgrade is ‘seamless operations’—the nurses’ station hasn’t had a single complaint about blacked‑out monitors, and the logistics department can check device statuses via a mobile app. Even more importantly, the medical‑grade electromagnetic compatibility of Guangwangshi switches has eliminated signal interference issues affecting our cardiac monitoring equipment,” said the head of the project management center.
