A hardwired 4G vehicle GPS tracker providing real-time positioning, route history, ACC ignition detection, geofencing, driving alerts, fleet management, and optional remote fuel or power cut-off.
Final pricing depends on configuration, quantity, taxes and shipping.
Sample availability, quantity and lead time depend on the selected model. Confirm the pilot scope before placing a production order.
The 4G Wired Vehicle GPS Tracker is designed for real-time vehicle positioning, fleet supervision, anti-theft protection, and driving-data management. Connected directly to the vehicle’s electrical system, it provides continuous operation without frequent manual charging.
The tracker is suitable for private cars, commercial fleets, trucks, taxis, rental vehicles, buses, logistics vehicles, and construction machinery.
The device uses GPS and BeiDou satellite positioning to determine the vehicle’s location. Position data is transmitted to the management platform through the 4G LTE network.
Managers can view the vehicle’s latest location, speed, direction, positioning time, ACC status, online status, and alarm information through a web platform or mobile application.
Unlike portable battery-powered trackers, the wired vehicle GPS tracker receives continuous power from the vehicle. This makes it suitable for long-term fleet deployment and frequent location reporting.
A built-in backup battery allows the device to send a power-disconnection alert and continue operating temporarily if the main vehicle power supply is removed.
The ACC wire detects whether the vehicle ignition is switched on or off. This information helps the platform identify vehicle start time, stop time, parking duration, driving activity, and unauthorized use.
ACC data can also support trip reports, utilization analysis, and fleet operating records.
The device can support multiple security and operating alerts, including:
Alarm records can be viewed through the management platform for security review and incident investigation.
The platform stores vehicle positioning reports and displays historical routes by date and time. Users can review driving paths, mileage, speed, stop locations, parking duration, and alarm events.
This feature is useful for fleet dispatch, delivery verification, vehicle utilization analysis, and driver management.
An external relay can be installed to support remote fuel or electrical circuit interruption. This function may help recover stolen vehicles or control unauthorized vehicle use.
For safety, the command should be executed only when the vehicle is stationary or moving below a configured safe-speed threshold. Installation must be completed by a qualified automotive electrician, and the circuit must be compatible with the vehicle.
The WECHATGPS platform supports:
The platform is accessible through computers, Android devices, and iOS devices.

Confirm that the tracker input voltage matches the vehicle electrical system
Install an activated 4G SIM card with a suitable data plan
Disconnect the vehicle power before beginning installation
Connect the positive power wire to a constant vehicle power source
Connect the ground wire securely to the vehicle chassis or negative terminal
Connect the ACC wire to the ignition signal if ACC detection is required
Install the optional relay only when remote fuel or power cut-off is required
Place the tracker in a concealed position away from metal signal obstruction
Keep the GPS antenna side facing upward whenever possible
Bind the device ID to the assigned vehicle on the management platform
Configure reporting intervals, geofences, speed limits, and alarm rules
Test positioning, ACC status, backup battery, alarms, and platform communication
Define the application, country, quantity, reporting interval and target battery life.
Agree the device, network, power system, payload and platform interfaces.
Test representative devices, coverage, power consumption and alarm delivery on site.
Approve the specification and pilot results, then plan production, installation and support.
PCB, enclosure, connectors, antenna and power design are reviewed against the installation and operating requirements.
Reporting intervals, event logic, payload encoding and remote configuration are defined in a versioned interface document.
