Cellular. Satellite. LoRa. One device.

TRACKbox 4 is Sensium's next-generation telematics platform, designed for fleets operating beyond traditional connectivity boundaries. It combines 4G LTE cellular, Direct-to-Cell satellite failover, and Sense Network (LoRa) in a single device, with True Path one-second telemetry and a 10+ year typical deployment lifetime. Designed and manufactured in Australia.

TB2 is the hard-wired cellular workhorse — the right choice for the bulk of a vehicle fleet operating inside the cellular grid. TB4 is the next-generation unit for fleets that operate past cellular coverage (utility crews, mining, agriculture, rural government). Both run the same firmware and report into the same Sensium Connect+ dashboard, so a mixed-TB2/TB4 fleet operates as one fleet.

Yes. TB4 includes Direct-to-Cell satellite connectivity alongside 4G LTE cellular. When the cellular network drops out, the device fails over to satellite automatically. No driver action required. This is the feature that pulls the deal for utility, mining, and agriculture fleets working past the cellular grid.

Because Sensium owns the firmware end-to-end, custom feature requests are developed in-house rather than routed through the overseas OEM process typical of reseller telematics. The classic example: a customer requested a 115 km/h speed buzzer, we shipped it in four days. Custom geofence triggers, integration with site systems, hazard zone alerts, and similar requests follow the same path.

Designed for 10+ year deployment. Some original Sensium units are still in service after seventeen years. The hardware is designed to outlast the typical vehicle lifecycle, which improves total cost of ownership materially compared to providers running three-year hardware churn cycles.

TB4 runs 4G LTE cellular as the primary path. When the cellular network drops out - past the nearest tower, in remote agricultural country, on a rural council road, or at a mine site - the device fails over to satellite automatically, with no driver action required. Iridium satellite is available in Australia today, and Direct-to-Cell (Starlink) is live in New Zealand and rolling out in Australia subject to local carrier availability.

TB4 connects over 4G LTE using enterprise-grade M2M connectivity on the Telstra network, with a store-and-forward design: if connectivity drops, the device records data locally and uploads the backlog when it reconnects. The unit uses a physical M2M SIM. Sensium bundles the connectivity, so it is not a separate line item customers manage.

TB4 carries a 3-year manufacturer's warranty and is designed for 10+ year deployment. An internal backup battery keeps the unit reporting for roughly 10 hours after a loss of vehicle power, so a disconnected battery or attempted theft still reports position and status rather than going dark.

TB4 uses multi-constellation GNSS, which typically delivers GPS accuracy within around 10 metres. Combined with True Path one-second telemetry, the result is route replay, geofence entry and exit timing, and arrival and departure events that reflect what the vehicle actually did rather than a sampled approximation.

No - TB4 is a powered, hard-wired in-vehicle unit aimed at fleets operating past the cellular grid. For non-powered assets such as trailers, skid bins, generators, and towed plant, the sealed battery-powered TB3 is the right device. Both report into the same Sensium Connect+ dashboard, so a mixed fleet is still managed as one fleet.
