Vehicle IoT Gateway

The VG33 Vehicle IoT Gateway is an advanced GPS tracker and sensor platform, providing fleet operators with real-time visibility and business-relevant reports that lower cost and increase productivity.

List price: $99 plus $33/mo license, or $27/mo with 3-year term (all-inclusive license includes cellular data, maintenance and support, and cloud-based software.)

Advanced GPS location technology for 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 VG33 integrates information from many different sensors, providing a comprehensive and intuitive view of your fleet. The VG33 monitors engine diagnostics, fuel efficiency, driver productivity, and safety. The VG33 is ideal for refrigerated fleets, supporting wireless temperature monitoring, and industrial fleets with visibility into power takeoff, lift arm, plows, sweepers, fluid tanks, gas pressure, and more.

Easy to install, secured with active tamper detection

With a flexible and intuitive mounting system, smart diagnostics connectors, and internal antennas, the VG33 installs in most vehicles in just a few minutes. Discreet mounting options minimize risk of tampering, and a built-in, rechargeable battery enables the VG33 to send a wireless alert in the event that it is unplugged from the vehicle.

Rugged, flexible device works in almost any vehicle

The VG33 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 VG33 is built for reliable performance under the rigors of industrial fleet operations.

Part of a complete, business-relevant solution

The VG33 is part of Samsara's complete solution to provide visibility into vehicles, drivers, cargo, mobile assets, energy, and industrial processes. With the VG33, operators can improve driver safety, analyze route performance, simplify reporting and compliance, increase driver productivity, and lower operating cost.
