Remote Substation CCTV Upgrade Project: Industrial Fiber Surveillance Network

1. Project Background

A utility infrastructure customer required a reliable industrial surveillance network for a geographically distributed outdoor site that included:

• Electrical distribution zones
• Perimeter fencing
• Remote monitoring checkpoints
• Equipment shelters
• Access control gates
• Outdoor storage areas

Because the monitoring locations were spread across a large area, traditional copper Ethernet deployment was not practical due to:

• Transmission distance limitations
• High lightning exposure risk
• Electromagnetic interference from industrial equipment
• Outdoor environmental conditions
• Difficulty in centralized power distribution

The customer specifically requested a solution capable of:

• Long-distance fiber transmission
• Industrial-grade reliability
• Centralized surveillance management
• PoE support for multiple IP cameras
• Scalable future expansion
• Stable operation in harsh outdoor environments

To meet these requirements, the project adopted a fiber-based industrial Ethernet architecture using:

IM-FP888GW as the core aggregation switch

IM-FP21008GW as the outdoor PoE distribution switch

IM-WP054GE as the compact edge access switch

The final solution created a robust industrial CCTV backbone suitable for 24/7 utility and perimeter security monitoring.

4. Device Roles

A. Core Aggregation Layer: IM-FP888GW

This Ethernet switch serves as the fiber aggregation center of the surveillance network.

Key Advantages

• 8 Gigabit SFP fiber ports
• Industrial managed architecture
• VLAN and traffic management
• Long-distance fiber aggregation
• Ring protection support
• Industrial EMC protection
• DIN-rail deployment

The IM-FP888GW aggregates all remote surveillance traffic and connects directly to the NVR/VMS platform.

It is especially suitable for:

• Utility substations
• Smart transportation
• Industrial campuses
• Mining environments
• Oil & gas facilities

The device supports industrial-grade operation and hardened protection for harsh environments.

B. Distribution Layer: IM-FP21008GW

This model is deployed at outdoor cabinets and remote surveillance poles.

Key Features

• 8 × Gigabit PoE ports
• 2 × SFP fiber uplinks
• IEEE802.3af/at/bt support
• Up to 90W PoE output
• Industrial temperature range
• ERPS ring support
• VLAN / QoS / SNMP management
• Surge protection

This DIN PoE switch powers high-consumption devices such as:

• PTZ cameras
• IR thermal cameras
• Wireless APs
• AI edge cameras

It also provides redundant fiber uplinks for uninterrupted surveillance operation.

C. Edge Camera Layer: IM-WP054GE

This compact switch is ideal for small camera clusters.

Deployment Examples

• Parking entrance
• Fence monitoring section
• Small warehouse
• Guard station
• Temporary outdoor deployment

Key Advantages

• Plug-and-play operation
• 4-port PoE downlink
