The AT5 is a 2G GSM GPS tracker manufactured by ATrack Technology Inc., a Taiwan-based telematics company. It is marketed under various brands, including Concox. Designed for advanced fleet management, it is a rugged, industrial-grade tracker known for its extensive I/O capabilities, two-way voice communication, and support for the 1-Wire® protocol (on the AT5i model) for driver identification and temperature monitoring.
✨ Key Features
The AT5 series is distinguished by its multifunctional hardware design and comprehensive accessory support.
-
Two-Way Voice Communication: The device features a built-in audio amplifier that supports hands-free calling and a “wire-tap” function, allowing the dispatcher to listen to in-vehicle audio remotely for situational awareness.
-
Advanced I/O & CAN Bus Support: With multiple digital inputs and outputs, the AT5 connects to fuel sensors, door locks, and panic buttons. It also supports CAN bus adapters, enabling reading of vehicle data like fuel consumption, RPM, engine load, and odometer directly from the vehicle’s ECU (Engine Control Unit).
-
Driver Behavior & Security: It has a ±16g 3-axis accelerometer (G-sensor) to detect harsh acceleration, braking, cornering, and collisions. The device supports up to 64 geofences, overspeed alerts, tow-away detection, and GSM jamming detection.
-
1-Wire® Interface (AT5i only): The “i” variant supports the 1-Wire protocol, allowing connection to iButton® keys for driver identification/authentication and Dallas temperature sensors for cold chain monitoring.
-
Data Security & Configuration: It utilizes AES-128 data encryption for secure communication and supports FOTA (Firmware Over-The-Air) updates, allowing remote upgrades without physical access to the device.

📱 Applications and Summary
The AT5 is a robust 2G tracker designed for depth of data rather than size. Its key strength lies in its integration capabilities. With RS232, CAN bus support, and 1-Wire connectivity, it is ideal for heavy equipment monitoring, cold chain logistics, and rental fleets requiring driver authentication.
Note: There is also a separate device called the NL-AT5 (by NimbeLink/Airgain). While it shares the “AT5” name, it is an LTE-M asset tracker with a primary battery (lasting up to 14 years), designed for tracking shipping containers and static assets rather than wired vehicle telematics. The specifications above refer specifically to the ATrack/Concox AT5 used in fleet management.
