Industrial Applications

1. Industrial IP Surveillance Aggregation

Deploying multiple high-definition IP pan-tilt-zoom (PTZ) cameras around a manufacturing facility.

Problem Solved

Standard switches lack the PoE power budget and high-bandwidth uplinks to handle dozens of 4K camera streams concurrently, leading to jitter and frame drops. With 215W PoE budget (up to 30W/port) and 10G SFP+ uplinks, the switch ensures continuous power and a bottleneck-free trunk link to the central NVR.

2. Substation Edge Network Deployment

Connecting remote terminal units (RTUs), PLCs, and human-machine interfaces (HMIs) in industrial cabinets or substation control rooms.

Problem Solved

Industrial cabinets are prone to high lightning-induced surges and extreme temperatures. The integrated 6KV surge protection guards the switch ports from transient voltage spikes, and the -10°C to 45°C operating range ensures reliable communication of process data to the SCADA system over 10G fiber uplinks.

3. Enterprise-to-Industrial Wireless AP Aggregation

Powering and backhauling a fleet of high-performance industrial dual-band Wi-Fi 6 wireless access points across a warehouse floor.

Problem Solved

Warehouse APs require dedicated power lines and high throughput. The switch eliminates localized power outlets by delivering up to 30W PoE power over long Ethernet runs, while 10Gbps SFP+ uplink ports prevent data congestion when hundreds of handheld barcode scanners roam across the network.
