Industrial Applications

1. High-Density IP Surveillance Networks

Powering and aggregating massive CCTV camera networks across corporate campuses or industrial complexes.

Problem Solved

Eliminates the complexity and cost of running separate power cables to up to 48 physical cameras. Features a generous 396W power budget to supply up to 30W per port, while L3 static routing keeps heavy multicast surveillance traffic isolated from primary corporate subnetworks.

2. Campus Wi-Fi Infrastructure Backhaul

Connecting, powering, and optimizing commercial wireless access points (APs) distributed across large multi-floor facilities.

Problem Solved

Solves localized power outlet scarcity and limits of copper Ethernet runs (100m). Supplies ample PoE+ power to modern high-density APs, while utilizing the 4 independent Gigabit SFP optical slots to connect back to the central server room over fiber-optic links without electromagnetic interference.

3. Automated Logistics & Warehouse IoT Integration

Aggregating and securing warehouse floor terminal devices such as barcode readers, RFID scanners, and industrial IoT gateways.

Problem Solved

Protects industrial floor networks against terminal spoofing and packet flooding. Advanced features like IP-MAC-Port-VLAN four-way binding ensure only authorized logistics scanners access the warehouse subnetwork, and DoS prevention guarantees zero network downtime during manufacturing runs.
