Compact Industrial 4G Router – RS232/RS485, Dual Ethernet, Secure VPN & Cellular

This Compact Industrial 4G Router is a robust, cost-effective networking solution designed for digital signage, vending machines, kiosks, IP cameras, HVAC systems, smart grid equipment, compressors, and Industry 4.0 applications. Its compact metal design allows easy embedding inside enclosures while offering secure, reliable 4G connectivity for remote communication.

With RS232, RS485 and dual Ethernet (WAN/LAN) interfaces, this router integrates seamlessly into legacy equipment as well as modern IoT systems. The optional LTE-M and NB-IoT variants provide extended coverage and lower power consumption for underground, rural or low-signal environments.

Built on an OpenWRT-based operating system, it supports advanced development in C/C++, and optional Python or LUA for custom edge applications. Multiple VPN protocols—including OpenVPN, IPsec, GRE, PPTP and L2TP—ensure secure communication for sensitive industrial data.

Perfect for applications such as:
✔ Digital signage & advertising displays
✔ Vending & ticketing machines
✔ Smart metering & power systems
✔ Remote IP camera networks
✔ HVAC and building automation
✔ Industrial controls & machinery
✔ Low-cost roadside & equipment telemetry

We keep stock in Australia, offer local technical support, and can assist with full integration into ProSight or any third-party IoT/SCADA system.
