Industrial 4G PoE Router

Model: R2120

 

Industrial 4G PoE Router Product Overview

A specialized industrial router designed for smart security and IoT applications, delivering stable cellular connectivity and advanced Power over Ethernet (PoE) capabilities.

● Advanced Power over Ethernet (PoE): Features 4 x PoE-PSE Ethernet ports (802.3af/at) to power and connect devices like IP cameras and access points through a single cable, simplifying installation. Includes remote PoE device management via RCMS to schedule reboots and power cycles.

● Stable & Redundant Connectivity:Combines 4G/3G/2G cellular, Wi-Fi, and Ethernet with dual-SIM automatic failover for resilient, always-on communications.

● Enterprise-Grade Security: Runs on the hardened RobustOS. Secures your network with a powerful stateful firewall and a comprehensive suite of VPNs, including IPsec, OpenVPN, and DMVPN.

● Simplified Cloud Management:Integrates fully with the RCMS cloud platform for centralized monitoring of your entire fleet, Over-the-Air (OTA) updates, and secure remote management of both the router and connected PoE devices.
