Samsara VG34 Gateway


Vehicle IoT Gateway

The VG34 Vehicle IoT Gateway is an advanced sensor platform for fleets, providing operators with real-time location and analytics, sensor data, WiFi hotspot connectivity, and ELD-ready hours of service logging.

Precise GPS tracking with real-time visibility

Samsara’s advanced GPS technology simultaneously reads from multiple independent satellite systems, providing precise, real-time location even in challenging geographical environments.

Provides complete visibility over vehicles, drivers, and operations

The VG34 integrates information from a variety of built-in and accessory sensors, providing a comprehensive and intuitive view of your fleet. The VG34 monitors engine diagnostics, fuel efficiency, driver productivity, and safety. The VG34 is ideal for refrigerated fleets, supporting wireless temperature monitoring, and specialized fleets with visibility into power takeoff, lift arm, plows, sweepers, fluid tanks, gas pressure, and more.

A platform for location, ELD, dash cams, and more

The VG34 is the hub of Samsara’s complete solution, enabling operators to implement ELD-ready hours of service logging, deploy Internet-connected dash cams for improved safety, connect wireless sensors to monitor reefers and cargo, and more.

High-speed 4G LTE Cellular Connectivity

The VG34 offers a 10x speed advantage over 3G devices, providing a high-speed data platform ideal for mobile apps, dash cameras, and HD video to increase productivity and enable new in-cab software tools. A built-in WiFi hotspot enables in-cab WiFi connectivity for tablets, laptops, and mobile devices.

Secure and easy to install with y-splitting cables and tamper alerts

With a flexible and intuitive mounting system, smart diagnostics connectors, and internal antennas, the VG34 installs in most vehicles in just a few minutes. Discreet mounting options minimize risk of tampering, and a built-in, rechargeable battery enables the VG34 to send a wireless alert in the event that it is unplugged from the vehicle.

Rugged, flexible device works in virtually any vehicle

The VG34 is equally at home in cars and light trucks, tractor trailers, and heavy duty, industrial, or specialized vehicles. With a rugged design tested for vibration, shock, moisture, and extreme temperatures, the VG34 is built for reliable performance under the rigors of industrial fleet operations.

Part of a complete, business-relevant solution

The VG34 is part of Samsara’s complete solution to provide visibility into vehicles, drivers, cargo, mobile assets, energy, and industrial processes. With the VG34, operators can improve driver safety, analyze route performance, simplify reporting and compliance, increase driver productivity, and lower operating cost.
