CAN and tachograph
Bus events travel the same channel as position, if the device has them.
GPS trackers
The tracker reports to the company platform. It does not listen on the internet.
Trackers in cars, telematics, CAN reading, tachograph and theft alarm. The fleet platform stays with you or with a supplier you admit into the tunnel. The fleet as a whole is described on a separate page.
ExampleExample: 80 company cars with a tracker. Position, a CAN event and a power-disconnect alarm go to the platform at headquarters. An illustrative scenario, not a client reference.
Alarm
Disconnect, tow, leaving a zone — to the platform inside the tunnel.
Consistent with the fleet
This page is about the tracker. Addressing for the whole fleet sits beside it.
What bounces off the edge
A tracker exposed as a server, or a platform that reaches it over the internet, reverses trust: a stranger who finds the address is closer to the vehicle than the dispatcher.
The SIM in the tracker is on the APN list and gets a private address. The report goes to the platform. Service entry is from headquarters. Where a vehicle leaves one network’s coverage, a second SIM or a Peplink router in the vehicle keeps the path — in open country, with Starlink as well.
Security
- No public IP on the tracker.
- The theft alarm goes to your platform, not to an open endpoint.
- The SIM is bound to the device where the operator can bind the IMEI.
Fleet telematics can sit in the chain of a transport service. Isolating the tracker shrinks exposure. It does not replace a tachograph duty or statutory compliance.
