Project Background
A transportation system integrator was tasked with deploying a roadside surveillance network along a newly expanded highway section in Southeast Asia.
The project required multiple outdoor surveillance cabinets distributed every 2–3 kilometers along the road.
Each cabinet needed to support:
- PTZ speed dome cameras
- ANPR/LPR cameras
- Outdoor wireless access points
- Environmental monitoring sensors
- Emergency alarm devices
Because many installation points were located in remote roadside areas without permanent maintenance staff, the customer placed strong emphasis on:
- High system reliability
- Remote management capability
- Fast network recovery
- Simplified power deployment
- Long-term operational stability under harsh outdoor conditions
Traditional commercial PoE switches were evaluated during the early planning stage, but several problems quickly appeared during testing.
Challenges Encountered
1. High-Power Outdoor Devices
The PTZ cameras used in the project required high PoE power during nighttime IR operation and motor movement.
Standard PoE+ switches could not provide stable power when multiple devices operated simultaneously.
Adding separate power supplies inside each roadside cabinet increased wiring complexity and maintenance difficulty.
2. Extreme Environmental Conditions
The deployment environment included:
- Summer cabinet temperatures above 60°C
- Heavy rain and humidity
- Lightning exposure
- Dust and roadside vibration
- Unstable field power conditions
Several commercial switches experienced overheating and random reboot issues during testing.
3. Network Availability Requirements
Because the highway surveillance system was connected to the regional traffic control center, network interruption was unacceptable.
The customer required:
- Fiber ring redundancy
- Automatic recovery during fiber interruption
- Stable video transmission during network failover
4. Maintenance Cost Concerns
Sending engineers to roadside cabinets for troubleshooting was expensive and time-consuming.
The customer wanted the ability to remotely monitor:
- PoE power consumption
- Device status
- Port conditions
- Temperature alarms
- Link failures
Solution
The integrator selected the IM-FP21008GW Managed DIN PoE++ Switch as the core node inside each outdoor surveillance cabinet.
Deployment Structure
Each roadside cabinet included:
- 4–6 IP cameras
- 1 outdoor wireless bridge
- Environmental sensors
- Fiber uplink connection
- Battery backup system
- IM-FP21008GW industrial PoE switch
The switches were connected through a G.8032 ERPS fiber ring topology along the highway.
The 2.5G SFP uplinks were used to aggregate multi-camera video traffic back to the traffic management center.
Why the IM-FP21008GW Was Chosen?
90W PoE++ Simplified Field Deployment
One major reason for selecting the switch was its IEEE 802.3bt PoE++ capability.
The switch provided:
- Up to 90W per port
- 480W total PoE budget
This allowed the integrator to directly power:
- PTZ dome cameras
- Outdoor wireless APs
- Radar sensors
without installing additional DC power systems inside the cabinet.
The customer reduced cabinet complexity and shortened installation time significantly.
Intelligent Power Management Improved Reliability
During deployment, engineers noticed that power stability was just as important as network stability.
The IM-FP21008GW offered several features that became highly valuable in real operation:
- PoE priority management
- Delayed PoE startup
- Real-time voltage/current monitoring
- Over-temperature protection
- Overload prevention
Critical devices such as PTZ cameras were configured with higher PoE priority.
Even during abnormal power conditions, key surveillance devices remained operational while lower-priority devices were temporarily limited.
This greatly improved overall system resilience.
Industrial Design Solved Environmental Problems
Unlike commercial switches previously tested, the IM-FP21008GW was specifically designed for industrial environments.
The deployment benefited from:
- -40°C to +75°C operating temperature
- IP40 metal housing
- Fanless thermal dissipation design
- 6KV surge protection
After deployment through peak summer months, the customer reported stable operation without the overheating problems experienced earlier with office-grade switches.
ERPS Ring Recovery Reduced Downtime
Fiber interruptions occasionally occurred during nearby road construction activities.
The G.8032 ERPS ring protection mechanism allowed the network to recover automatically within milliseconds.
In several real incidents, video streams continued operating without manual intervention from the control center.
For the customer, this was one of the most important improvements compared to older surveillance deployments.
Remote Monitoring Reduced Maintenance Visits
Using SNMP and web-based management, the operator could remotely check:
- PoE consumption per port
- Link condition
- Device online status
- Temperature alarms
- System logs
Relay alarm outputs were also connected to the cabinet alarm controller.
If power abnormalities or link failures occurred, the system automatically generated alerts for the maintenance team.
This reduced unnecessary site visits and improved fault response efficiency.
Project Results
After deployment, the customer achieved several measurable improvements:
- Reduced field wiring complexity
- Faster installation time
- Lower maintenance costs
- Improved network uptime
- Stable operation under harsh outdoor conditions
- Simplified remote troubleshooting
The customer later expanded the same architecture into additional highway surveillance sections.
Conclusion
In this project, the IM-FP21008GW was not simply used as a network switch.
It became the central infrastructure node responsible for:
- Power delivery
- Network aggregation
- Ring redundancy
- Remote monitoring
- Alarm integration
For outdoor surveillance, transportation infrastructure, perimeter security, and unmanned industrial sites, intelligent industrial PoE switches are increasingly replacing traditional standalone power and networking architectures.
The IM-FP21008GW provided the customer with a more reliable, maintainable, and scalable deployment model for long-term infrastructure operation.
