AT Fleet

IoT tracker with many interfaces for fleet management

The CarLoc® AT Fleet, IoT tracker was specially designed for quick installation and universal use. It is installed without additional external antennas inside the vehicle or outside, where it can be exposed to wind and weather. The large selection of interfaces and standard protocols means that it can be connected to current sensors and sub-systems. CarLoc® AT Fleet has reliably accompanied vehicles over the years and gives information about the vehicle position and load status (optional) at any time. High functionality, paired with comfortable configuration options, allow tailor-made operation at minimum cost. The intelligent device logic automatically reports all processes relevant to the transport to the CarLoc® Portal – and this worldwide.
CarLoc® AT Fleet provides precise locating (even in difficult environments) using a highly sensitive GPS receiver. Remotely configurable settings, data storage for recordings over several months as well as the option of monitoring up to 6,000 geographical zones supplement the IoT tracker.
