Core Engineering Features
Continuous Hardwired Power
Direct fuse box connection eliminates reliance on cigarette lighters or OBD ports, ensuring uninterrupted 24/7 power delivery. Internal voltage regulator safeguards internal circuits against alternator spikes and engine cranking surges.
Buffered Real-Time Tracking
Configurable reporting intervals optimize cellular bandwidth based on time, distance, or heading thresholds. Stores up to 3,000 offline buffer points during cellular dropouts, automatically re-uploading data upon signal restoration.
Driver Behavior & Ignition Sensing
Hardware-level ACC detection accurately records engine run-time and idle duration. Integrated 3-axis accelerometer registers harsh braking, rapid acceleration, sharp cornering, and collision impacts.
Remote Immobilization
Low-current digital output drives an external relay to cut fuel supply or vehicle ignition upon verified server command. Speed-threshold logic prevents engine cutoff at high velocities for operational safety.
Wiring & Installation Guide
Wire Harness Definition
Red Wire: DC Power Input (Connect to constant 9V–90V power source)
Black Wire: Ground (Connect to chassis ground or battery negative terminal)
Orange Wire: ACC Ignition Detection (Connect to vehicle ignition switch output)
Yellow Wire: Digital Output (Connect to external relay control terminal)
White Wire: Digital Input (Connect to panic button or door sensor)
Installation Best Practices
Mount the unit horizontally with the labeled side facing upward, free from metallic obstructions.
Conceal the device securely beneath the dashboard or behind instrument clusters to prevent tampering.
Always install a 2A inline fuse on the red power wire to protect the vehicle electrical harness.
Telematics & Monitoring Functions
Protocol & Server Integration
Supports binary and hexadecimal communication protocols compatible with major tracking server architectures.
Configurable TCP/UDP and MQTT data transmission modes with keep-alive mechanism.
Seamless Integration: Fully compatible with mainstream third-party GPS tracking platforms (such as Traccar, Navixy, etc.) via open protocol documentation and developer SDK support. (Newly Added)
Event Alarm Management
Tamper Alert: Instant notification triggered if the main power cable is cut or disconnected.
Vibration Alert: Activates upon unauthorized vehicle movement or towing while parked.
Overspeed Alert: Automatic reporting when pre-set velocity limits are exceeded continuously.
Geofence Breach: Real-time entry and exit event triggers for designated zones.
OEM/ODM Customization
Hardware Modification
PCB layout adjustments and interface expansion (e.g., adding CAN bus J1939/OBDII reader chips or dual RS485 ports).
Custom enclosure mold design, color matching, and laser-engraved corporate branding.

Frequently Asked Questions
Q: What is the main advantage over an OBD tracker?
A: Hardwired units are permanently concealed to prevent driver tampering or theft detection, while supporting a much wider voltage range (9V–90V) for heavy-duty applications.
Q: How does the device prevent vehicle battery drain during long parking periods?
A: The unit enters an ultra-low power sleep mode (< 3mA) when the ignition is off and no movement is detected, preserving vehicle battery integrity while maintaining network standby.
Q: Can the communication protocol be integrated into our proprietary server software?
A: Yes. Complete protocol documentation, binary configuration tools, and technical engineering support are provided for cloud server integration.
Q: What is the minimum order quantity for custom branding and firmware adaptation?
A: The standard MOQ for customized labeling, tailored cable harnesses, and proprietary server protocol integration starts at 500 units.
Q: How are firmware updates managed after installation?
A: The device supports Over-The-Air (OTA) remote firmware upgrading via GPRS/LTE commands, allowing remote maintenance without physical vehicle access.
