Milesight - AT101
Outdoor Asset Tracker

The Milesight AT101 is an exceptional outdoor asset tracker that uses GNSS and Wi-Fi AP MAC Address scanning to ensure awareness of critical assets. The AT101 includes tilt and temperature sensors for comprehensive data collection and to trigger alarms against tampering. Wi-Fi scanning provides positioning assistance in spaces with poor GNSS signals. Low power consumption option allows operation for over 15 years with twice-daily reports.

In addition to supporting NFC configuration similar to other Milesight sensors, the AT101 supports Bluetooth configuration. Build a virtual perimeter around a specific location with geofencing. Users can receive alerts when assets leave or return to the defined zones. Data can be stored locally with 1000 historical records to secure the traceability of reported information. With the support of data retransmission, the AT101 guarantees data transfer even if the network is down.

The AT101 is suitable for a wide range of applications such as logistics, equipment tracking, livestock farming and supply chain management. Three tailored modes of operation make the outdoor asset tracker suitable for many tracking applications: Motion mode reports positioning based on start/stop movement, Timing mode monitors assets for specified time periods and Periodic mode customises reporting intervals from one minute to one day.
