The JM-VL01 is a 4G LTE GPS tracker manufactured by Jimi IoT (Concox), positioned as a versatile solution for fleet management, logistics, and vehicle security applications. Announced in September 2020, it serves as a modernized successor to 2G/3G trackers, offering 4G connectivity alongside a distinctive WiFi hotspot function that allows the device to double as an in-vehicle mobile router.
✨ Key Features
The JM-VL01 distinguishes itself through its connectivity options and accessory support.
-
4G LTE Connectivity with Fallback: The device operates on 4G LTE networks while maintaining backward compatibility with 3G (UMTS/WCDMA) and 2G (GSM) networks, ensuring reliable data transmission across varying coverage areas.
-
WiFi Hotspot Functionality: A standout feature is the built-in 2.4GHz WiFi hotspot, which allows the tracker to function as a mobile router. This enables passengers or other onboard devices to connect to the internet using the vehicle’s cellular connection, making it useful for mobile offices or passenger convenience.
-
RS485 Interface for Sensors: The device includes an RS485 serial port, which allows connection to optional fuel level sensors and temperature sensors. This makes the JM-VL01 suitable for fuel theft prevention and cold chain monitoring applications.
-
Driving Behavior Analysis: The built-in accelerometer monitors driver behavior and triggers alerts for harsh acceleration, harsh braking, harsh cornering, and collision events, helping fleet managers improve driver safety.
-
Remote Vehicle Control: Supports remote fuel/power cut-off via an installed relay. For safety, this function only activates when the vehicle speed is below 20 km/h and GPS has a valid fix.
-
Emergency Panic Button: An external SOS button can be connected, allowing drivers to trigger emergency alerts and calls to preset SOS numbers.
-
Rugged and Weather-Resistant: Rated IP65, the device is protected against dust ingress and low-pressure water jets, ensuring reliable operation in harsh outdoor environments.
-
Ignition Detection: Monitors the vehicle’s ACC (accessory) status to accurately track ignition on/off states and optimize power consumption.
