Hardware & PCB design
PCB, enclosure, connectors, antenna and power design are reviewed against the installation and operating requirements.

A waterproof hardwired 4G GPS tracker for cars, motorcycles, trucks and fleet vehicles. It supports real-time positioning, ACC ignition detection, geo-fence alerts, route playback and remote monitoring through mobile apps and a web platform.
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 Waterproof Wired Vehicle GPS Tracker is designed for reliable, continuous monitoring of cars, motorcycles, trucks, commercial vehicles and fleet assets. It connects directly to the vehicle’s power supply and transmits real-time location data through 4G LTE or compatible 2G mobile networks.
The compact, water-resistant enclosure makes the tracker suitable for concealed installation in vehicles that operate in rain, dust, vibration and other demanding conditions. Users can monitor vehicle locations, ignition status, historical routes and alarm events through an Android app, iOS app or web-based tracking platform.
The device combines GPS and BeiDou satellite positioning with LBS and assisted positioning. When satellite signals are available, it provides accurate outdoor location information, including vehicle position, speed, direction and positioning time.
Location data is transmitted to the tracking platform through the cellular network. The reporting interval can be configured according to different fleet-management, security and power-consumption requirements.
The tracker uses a sealed, water-resistant housing to protect its internal electronics from rain, splashes and dust. It is suitable for motorcycles, electric bicycles, trucks, construction vehicles and other equipment where the installation environment may be exposed to moisture.
For dependable operation, the wiring connections should also be insulated and protected against water after installation.
Unlike rechargeable portable GPS trackers, this model connects directly to the vehicle battery. The wired power supply supports continuous vehicle monitoring without frequent manual charging.
The compact enclosure can be installed in a concealed position, making the device difficult to discover or remove. The input voltage and wiring method should be confirmed before installation.
The ACC wire detects whether the vehicle ignition is on or off. Fleet managers can check ignition status, driving time, parking duration and vehicle usage through the management platform.
ACC data can also support vehicle utilization reports, unauthorized-use detection and more accurate trip records.
Users can create virtual geographic boundaries around offices, warehouses, construction sites, delivery areas or approved operating zones.
When a vehicle enters or leaves the configured area, the platform can generate an alert. This function is useful for fleet supervision, rental vehicle management and unauthorized movement detection.
The mobile app and web platform store historical positioning records. Authorized users can review previous travel routes, stop locations, driving times and movement history.
Route playback helps businesses analyze vehicle usage, confirm delivery journeys, investigate abnormal movement and improve fleet scheduling.
Depending on the configured firmware and platform, the tracker can support several vehicle security and management alarms:
Geo-fence entry alert
Geo-fence exit alert
Overspeed alert
External power disconnection alert
Vibration alert
ACC ignition alert
Abnormal movement alert
Offline device alert
Alarm records can be viewed through the application or web management platform.
Users can manage vehicles through Android and iOS mobile applications or a computer-based web platform. The system can display vehicle names, device numbers, latest locations, positioning times, speeds, ACC status and alarm records.
The platform supports individual vehicle monitoring and centralized fleet management, making it suitable for both personal vehicles and large commercial fleets.
This waterproof wired GPS tracker can be used for:
Private car security
Motorcycle anti-theft monitoring
Truck location tracking
Logistics fleet management
Rental vehicle monitoring
Taxi fleet management
Delivery vehicle tracking
Construction machinery monitoring
School bus management
Commercial vehicle dispatching
Outdoor equipment tracking
Install the tracker in a concealed position with the GPS antenna side facing upward. Avoid mounting it directly beneath thick metal panels because metal can weaken satellite signals.
Connect the positive wire to the appropriate vehicle power supply, connect the negative wire securely to ground and connect the ACC wire to the vehicle ignition signal. Wiring work should be completed by a qualified installer.
After installation, activate the SIM card, configure the APN and server information, add the device ID to the tracking platform and test the GPS location, ACC status and alarm functions.
