Wireless Street Light Monitoring & Cabinet-Level Control Solutions
Upgrade your smart street lighting system without touching a single fixture. Deploy our Sub-GHz LoRa modems directly into Lighting Control Cabinets (LCC) for immediate, circuit-level telemetry and control.
Explore The Architecture ↓The Challenge: The OPEX Trap & Isolated Infrastructure
Traditional street lighting relies on blind fixed schedules. Upgrading them usually involves impossible trenching or bankrupting the municipality with per-lamp cellular data fees.
The Cellular OPEX Trap
Cellular solutions work, but putting a 4G/LTE modem on every light pole requires a SIM card and a monthly data plan. The recurring data costs kill the ROI of the project for thousands of lights.
Zero Network Visibility
A bad light is dark until someone complains. Maintenance crews have to drive routes and burn fuel and labor hours just to find out which circuits have tripped in old control cabinets.
The Trenching Nightmare
Upgrading legacy infrastructure doesn’t mean tearing up the pavement. You cannot economically run new RS485 communications wires to decades-old cabinets in dense urban grids.
End-to-End Wireless Architecture
From the control cabinet to the SCADA system: Select the physical topology that matches your municipal grid.
Utilize Sub-GHz LoRa to collect telemetry from distributed Lighting Control Cabinets (LCC) without per-lamp hardware.

Protocol Gateways for Isolated Systems
Legacy street lighting components cannot directly communicate with modern IT networks. Our Serial Device Servers and Protocol Gateways act as translators, converting raw Modbus RTU telemetry into Modbus TCP or MQTT payloads, seamlessly bridging lighting standards with industrial SCADA.

Fiber Optic Rings for Highway Arteries & Tunnels
For 10-mile highway stretches and tunnels where wireless signals face structural limitations, deploy our Industrial Ethernet Switches. Establish a Gigabit fiber-optic ring that guarantees zero-latency telemetry and absolute immunity to electromagnetic interference along road arteries.
Circuit-Level vs. Per-Lamp Control: Why Sub-GHz LoRa Wins
Deploying a true smart street lighting system must make financial sense. Our wireless street light control system guarantees high ROI by eliminating the need to equip every individual light fixture with an expensive NEMA node.
Cabinet-Level P2MP Polling (Zero LoRaWAN Complexity)
Forget the complexity of city-wide LoRaWAN Network Servers and per-lamp nodes. For industrial parks, university campuses, and highway segments, Valtoris utilizes Private Point-to-Multipoint (P2MP) LoRa to create an invisible, zero-latency RS485 bridge between your main PLC and distributed Lighting Control Cabinets (LCC).
- Transparent Modbus RTU: No cloud parsing required. Your master SCADA polls remote LCC energy meters directly, just as if they were hardwired.
- Radical Cost Reduction: One VT-LR600 controls an entire street circuit. Bypass the need to buy and maintain hundreds of individual lamp controllers.
- Zero Cellular Fees: Sub-GHz LoRa covers 2-5km campus radiuses natively. Send data back to the central gateway without paying per-modem monthly SIM subscriptions.
| Deployment Model | Hardware Scope | Recurring OPEX (Data) | Maintenance Impact |
|---|---|---|---|
| Cellular (Per-Lamp) | 1 Node per Light Pole | High. $5-$15 per node/month. | Requires bucket trucks for node replacement. |
| Valtoris LoRa (LCC Level) | 1 Node per Circuit Cabinet | $0. Private Sub-GHz network. | Ground-level access inside LCCs. |
Protocol Translation & Edge Execution
Bridging legacy lighting standards with modern industrial SCADA.
Direct MQTT / SCADA Integration
The VT-LR601 Master Gateway features built-in MQTT capability. It automatically polls the remote Modbus RTU meters located in field cabinets, packages the telemetry into JSON payloads, and pushes it directly to your AWS, Azure, or municipal street lighting management platform—without requiring a separate Industrial PC.
Failsafe Circuit Actuation & Monitoring
Connect your street circuit contactors directly to the 8CH-IO Remote I/O Controller. It utilizes 5A Relay Outputs (DO) to physically switch street segments on/off, while utilizing Analog Inputs (AI) to read 4-20mA current transformers—instantly detecting dead bulbs or circuit faults. If the main network drops, the edge logic maintains schedules safely.
Built for the Outdoors: Surviving Extreme Conditions
Municipal cabinets are unforgiving environments. Commercial-grade IoT devices fail here. You need industrial resilience.
Lightning Surges & Extreme Temperatures
Street cabinets endure brutal microclimates and frequent lightning strikes. All Valtoris industrial modems and I/O controllers feature high-voltage opto-isolation on RS485 terminals, robust surge protection, and are certified for wide-temperature operation from -40°C to +85°C. They survive where cheap IoT chips burn out.
Backhaul Connectivity: 4G/LTE Watchdogs
When installing the VT-LTE400 industrial router as the primary backhaul in urban retrofits, network drops are inevitable. Our routers feature hardware watchdogs and automated failover mechanisms, ensuring the router self-recovers and re-establishes the VPN tunnel without requiring a technician to drive to the site for a hard reset.
