I. Solution Background and Pain Points
With the rapid development of the modern security industry, the deployment density of high-definition and ultra-high-definition (4G/8K) cameras in scenarios such as parks, factories, campuses, and hospitals is increasing. Traditional video surveillance networks face the following severe challenges:
Limited Transmission Distance: The transmission distance of the Ethernet port (RJ45) is only 100 meters, which cannot cover large parks.
Bandwidth Bottlenecks and Lag: When hundreds of video streams converge concurrently, insufficient backbone bandwidth can easily lead to packet loss, latency, and lag.
Complex Network Architecture: The isolation (VLAN) of cross-regional and cross-departmental monitoring networks and the interconnection between network segments place extremely high demands on the routing and forwarding capabilities of core equipment.
Poor Environmental Adaptability: Outdoor monitoring boxes or mini-server rooms experience large temperature fluctuations, making network equipment prone to overheating and crashing, or hardware damage due to lightning strikes or static electricity.
II. Solution Design Topology
This solution adopts a typical all-fiber three-layer network architecture of "access-aggregation-core", with the HSGQ-5536C serving as the core/large node aggregation switch of the monitoring center.
III. Core Solution Advantages Based on HSGQ-5536C
1. Ultra-high Bandwidth and Flexible Ports: Completely Eliminate Video Stuttering
All-Fiber Backbone Transmission: The HSGQ-5536C features 16 Gigabit SFP optical ports and 4 10 Gigabit (10G SFP+) optical ports. The 4 10 Gigabit ports can be directly connected to core storage server clusters or ultra-large data centers, providing up to 128Gbps of switching capacity and 96Mpps of packet forwarding rate, supporting hundreds of concurrent 4K video streams with zero latency.
Flexible Adaptability (8 Gigabit Combo Ports): Network administrators can freely choose to use network cables (RJ45) to connect the local NVR or fiber optic cables (SFP) to connect remote devices, greatly improving cabling flexibility and reducing procurement costs, depending on the actual environment of the project site.
2. Robust Layer 3 Routing Protocols: Efficient Interoperability and Isolation Across Multiple Network Segments
Line-speed Layer 3 Forwarding (RIP / OSPF / VRRP): Supports IPv4/IPv6 dual-stack and OSPFv2/v3 dynamic routing protocols. In large-scale surveillance networks, different areas (such as administrative areas, production areas, and living areas) can be divided into different VLANs. The HSGQ-5536C can perform cross-VLAN Layer 3 routing locally, reducing the burden on the upstream gateway.
VRRP Virtual Router Redundancy: Supports hot backup of multiple switches. When the primary core device fails, the backup device takes over within seconds, ensuring uninterrupted video surveillance.
3. High-Reliability Industrial-Grade Design: Guaranteed Stable Operation in Harsh Environments
High-Level Lightning and Static Electricity Protection: Equipped with common-mode ±6KV surge protection and contact ±6KV and air ±8KV electrostatic discharge protection standards. Effectively reduces the probability of damage to core equipment caused by lightning strikes through fiber optic/network cables. Wide-Temperature Operation and Intelligent Self-Healing: Supports operating temperatures from -10℃ to 55℃. Built-in RTC real-time clock chip and supercapacitors meet the stringent time continuity requirements of industrial-grade equipment.
Intelligent Ring Network (ERPS) and Link Aggregation (LACP): Supports ERPS ring network protocol and LACP dynamic link aggregation. When a fiber optic cable is accidentally severed, the network can automatically switch to a backup link within milliseconds, achieving network self-healing.
4. Unified EDMS Cloud Operation and Maintenance: Significantly Reduces Enterprise Management Costs
MQTT Centralized Cloud Management: The device has a built-in MQTT module, supporting one-click connection to the EDMS cloud management platform via a secure protocol.
Remote Visualized Operation and Maintenance: Maintenance personnel can remotely monitor device operating status, configure VLANs, and issue QoS policies through a bilingual (Chinese/English) web interface or cloud-based system without being physically present on-site. They can also visually locate link faults on a map, significantly improving subsequent maintenance efficiency.
IV. Typical Application Scenarios
Smart Industrial Park/Large Factory: Utilizing gigabit fiber optics to break the 100-meter distance limitation, all surveillance videos from the surrounding area, factory buildings, and warehouses are aggregated over long distances with low loss to the main control room.
Digital Campus/Hospital Network: Combining QoS traffic priority policies, bandwidth is prioritized for video surveillance and video conferencing, avoiding packet loss in surveillance footage caused by downloading large files or during peak network periods.
Smart Hotel/Supermarket: Balancing wireless AP access management and indoor high-definition surveillance network, a single device can simultaneously support multiple services.
V. Equipment Selection Recommendations
Core Switch: HSGQ-5536C (Layer 3 managed, 1U rack-mountable deployment in the monitoring center).
10 Gigabit Optical Module: HSGQ 10G SFP+ multimode/single-mode optical module (for uplink storage NVR forwarding).
Access Switch: Depending on the number of front-end cameras, the following options are available: HSGQ-3310P (8 Gigabit Electrical (PoE) + 2 Gigabit SFP Optical L2+ managed PoE switches) and HSGQ-3330P (24 Gigabit Electrical (PoE) + 2 Gigabit Optical-to-Electronic Combo ports + 2 Gigabit SFP Optical L2+ managed PoE switches).
Front-end Transmission: Fiber optic SFP 1G/10G series optical modules and industrial-grade fiber optic transceivers.
VI. Summary This solution uses the HSGQ-5536C Layer 3 managed switch as its backbone core, making full use of its large buffer (12Mbit), high bandwidth (10 Gigabit uplink), rich Layer 3 protocols, and industrial-grade protection features to build a "high bandwidth, low latency, easy management, and strong security" all-fiber high-definition video surveillance transmission network for enterprises. It is an ideal choice for the implementation of modern smart security projects.
