Industrial Applications

1. Remote Monitoring of Distributed Industrial Equipment

Establishes encrypted IPSec/PPTP VPN tunnels directly from remote water/wastewater treatment or pumping stations to a central SCADA server, providing secure field PLC communications [1.1.2].

Problem Solved

Eliminates security vulnerability of exposing PLCs to the public internet. The passive cooling/fanless design prevents particulate accumulation failures common in dusty control panels.

2. Secure Substation Edge Networking

Provides secure, managed local network integration for unmanned power or chemical substations connecting up to 30-50 localized sensors and field monitoring units.

Problem Solved

Prevents unauthorized local network access and malicious interventions using built-in ARP protection (IP-MAC binding) and DoS attack prevention, while accepting standard 100-240V AC utility power.

3. Facility Security Camera & Access Control Segmentation

Enables the segregation of high-bandwidth CCTV cameras, security card readers, and up to 10 managed wireless APs from primary control networks.

Problem Solved

Avoids video stream congestion on critical manufacturing execution systems (MES). The integrated AP controller manages remote security terminals without requiring dedicated wireless hardware controllers.
