Valtrack V4 is a low cost GPS tracking device which supports 4G-LTE-CAT1 networks. Its based on the ESP32-C3FH4 chipset and comes with built-in GNSS patch antenna and support for external GNSS active antenna. Program Valtrack V4 via the micro USB port with the help of VS Code and ESP-IDF, Espressif’s official IoT Development Framework for the ESP32. Valtrack V4 supports direct connection to a vehicle’s battery and backup battery for emergency uses.

This device can be used for tracking two-wheelers, four-wheelers and any other mobile equipment. Know the real time location of the vehicle, aid in prevention of theft, and recover it with the help of the on-board motion sensor. Valtrack V4 can be customized to send alerts when movement is detected, and since it logs data continuously to the server, you can know the route the vehicle has traveled.
