Industrial Applications

1. Industrial High-Definition IP Surveillance Networks

Utilizes the 16 integrated Gigabit PoE+ ports to connect, power, and transfer data from high-definition PTZ IP security cameras or thermal monitoring cameras across manufacturing lines.

Problem Solved

Eliminates the cost and difficulty of routing separate electrical power lines to remote camera structures by supplying up to 30W per port (250W total budget) through standard Ethernet cables, while maintaining high-frame-rate video feeds.

2. Factory-Wide Wireless AP & Device Connectivity

Powers and manages factory-wide wireless Access Points (APs) and IIoT gateways using Gigabit PoE+ and centralized cloud platforms to achieve full wireless telemetry and operator tablet coverage.

Problem Solved

Simplifies multi-device hardware commissioning through Zero-Touch Provisioning and cloud web-remote management, allowing site engineers to troubleshoot connected nodes remotely without physically accessing overhead rack cabinets.

3. Segmented Industrial Control Networks (OT/IT Segmentation)

Divides time-critical OT network layers (PLCs, SCADA hosts, HMIs) from Standard IT network systems through secure 802.1Q, MTU, and port-based VLAN segmentation.

Problem Solved

Prevents standard administrative office traffic, multicast storms, and network loops from congesting or compromising machine control communications, ensuring maximum uptime for automation setups.
