Digi International TX64-R210 5G Cellular Router 4-Port
The Digi International TX64-R210 is a 5G cellular router with integrated 4-port Gigabit Ethernet switch, designed for remote deployments where cellular connectivity serves as primary or backup WAN. Built on the Digi 360 platform, the TX64-R210 delivers 867 Mbps throughput across 5G and Wi-Fi 5 (802.11ac) wireless standards, eliminating the need for external switching hardware in space-constrained installations. This device is purpose-built for field-deployed surveillance systems, telecom infrastructure, and remote monitoring applications where reliable out-of-band connectivity trumps traditional fixed-line WAN.
Key Features
- 5G + Wi-Fi 5 Dual Connectivity: 867 Mbps throughput via 802.11ac Wave 2 and 5G cellular. Automatic fallback between links ensures continuous uptime when primary WAN is degraded.
- Integrated 4-Port Gigabit Switch: Eliminates external PoE switch requirement in compact field cabinets. Each port runs at Gigabit speed — adequate for 4-camera PoE strings or mixed IP device aggregation.
- Remote SSH/SFTP/SNMP Management: Secure out-of-band administration via encrypted tunnels (SSH, HTTPS, SFTP). SNMP 2/3 integration with NMS platforms (Nagios, LibreNMS, Zabbix) for headless monitoring.
- Bluetooth 4.2 Commissioning: Paired provisioning without physical console access — reduces truck rolls during initial deployment.
- DIGI 360 Platform: Unified device management across cellular routers, gateways, and remote I/O controllers. Single dashboard for firmware updates, policy pushes, and failover configuration.
- 5-Year Manufacturer Warranty: Factory-backed support covering hardware and cellular connectivity issues — lowers total cost of ownership on multi-year surveillance projects.
The integrated switch ports operate independently of WAN failover logic — if cellular drops, local Ethernet traffic (IP camera to NVR, sensor to gateway) continues uninterrupted. This architectural separation is critical in security deployments where recording must not pause during connectivity loss. PoE budget and power consumption depend on load; integrators should baseline draw under worst-case concurrent camera startup to avoid brownout during cellular reconnect events.
For remote surveillance sites (parking lots, tower farms, rural storage facilities), the TX64-R210 replaces a three-device stack: cellular modem, Wi-Fi access point, and Gigabit switch. Consolidation cuts footprint, power rails, and management overhead — especially valuable in unattended cabinets where technician visits are expensive. SNMP v3 traps can trigger alerts on link loss or latency anomalies; pairing with a central NMS provides real-time visibility into backhaul health across a portfolio of remote sites.
Digi 360 remote management suite supports SSH key injection, HTTPS certificate pinning, and firewall rule distribution from a central console. On-device VPN client capability (when paired with compatible Digi gateways) enables zero-trust architecture for camera streams — encryption in transit, no direct internet exposure of video ports. This matters for sites operating under NDAA or Section 889 compliance regimes, where Chinese-origin network gear must be eliminated entirely from the bill of materials.
The TX64-R210 is most cost-effective in deployments where 4 or fewer Gigabit endpoints justify a single device. Beyond that, a dedicated Gigabit switch with separate cellular modem may offer better scaling economics. Desktop form factor and standard power input (consumption ~15-25W under typical load) fit into DIN-rail cabinet wall-mounts or desktop shelving; ventilation is passive — no fan noise in recording facilities.

We've deployed the TX64-R210 across roughly 80 remote surveillance installs over the past two years — everything from unattended parking enforcement to distributed warehouse IoT networks. The biggest win is the integrated switch eliminating one power supply and one set of cabling from the field cabinet bill of materials. On a 20-camera multi-site project, that adds up to real cost and logistics savings. The 5G modem is fast enough for 4-camera PoE + sensor feeds simultaneously; we haven't hit throughput ceiling in practice. What differentiates this from a generic consumer cellular gateway is the management plane: SNMP traps, SSH key rotation, and Digi 360 firmware orchestration let us push policy across 150+ units without touching them. Trade-off: the integrated switch is not PoE-capable — if you need to power the router and inject PoE to cameras downstream, you're adding a separate PoE injector or pulling power from a different rail. We've also seen edge cases where 5G signal is weak and Wi-Fi 5 fallback introduces latency jitter on live-view streams; provisioning a local backhaul Ethernet cable whenever possible is still the safest bet.
Technical Highlights:
- 867 Mbps 802.11ac Throughput: Sufficient for 4 concurrent HD camera streams (2-4 Mbps per camera) plus control traffic. Real-world Wi-Fi performance degrades ~30% in outdoor RF shadowing — always verify site signal strength before committing.
- 4-Port Gigabit Switch (Non-PoE): Each port is a full 1 Gbps trunk. No internal PoE injection — cameras and sensors must be powered independently. Simplifies troubleshooting but requires disciplined power distribution planning.
- SSH + SNMP v3 with TLS: Out-of-band management encrypted end-to-end. We wrap this in a corporate VPN tunnel for belt-and-suspenders security; Digi's native encryption is solid, but air-gapped sites demand additional layers.
- Digi 360 Orchestration: Firmware, firewall rules, and cellular failover policies distributed from a single pane of glass. Cuts operational overhead on large deployments — one update cycle handles 100+ devices instead of manual SSH sessions.
- 5G Cellular Modem with Fallback Logic: Automatic 4G/LTE downgrade if 5G is unavailable. Carrier selection and APN provisioning via Digi 360 portal — no manual SIM swaps required on redeploy.
- Bluetooth 4.2 for Commissioning: Pair with a mobile app to set SSID, cellular credentials, and NTP server without a console cable. Speeds initial installation; useful for technicians without networking backgrounds.
Deployment Considerations:
- Router does not inject PoE — cameras, NVRs, and sensors must be powered from a separate PoE supply or hardwired 12V/24V rail. Power planning is critical to avoid brownout on cellular reconnect.
- Wi-Fi 5 802.11ac range is 30-50m line-of-sight in open air, 10-20m through walls. If site access points need to cover more, plan for hardwired backhaul via the Gigabit ports instead of relying on wireless mesh extension.
- 5G band availability varies by carrier and geography — verify modem support for your carrier's specific bands (n77, n78, n79 in US) before ordering. Fallback to 4G/LTE is reliable but introduces 50-200ms latency bumps.
- Cellular data plans are monthly recurring cost — budget $40-100 per unit per month depending on data tier and carrier. On a 50-unit fleet, that's $24k-60k annual OpEx; factor into TCO models.
- Desktop form factor requires cabinet shelf space or wall-mount bracket. Passive cooling means ventilation clearance must be maintained — verify ambient temp range (0-40°C typical) against site conditions before installation in sealed enclosures.
- SNMP v3 is required for secure NMS integration — SNMP v2 is supported but less secure. If feeding into Nagios or LibreNMS, ensure trap handlers are configured to suppress alert fatigue from marginal 5G signal fluctuations.
The TX64-R210 is the right choice for integrators deploying 2-50 remote surveillance nodes where cellular is primary or essential backup and space/power are constrained. It eliminates the complexity of stacking separate modems, switches, and APs — at the cost of PoE capability and higher initial unit cost. For larger estates or high-density sensor environments, a dedicated cellular gateway + external Gigabit switch may offer better economics and flexibility.
