Driving Behavior Analysis
Monitors vehicle behaviors such as rapid acceleration, deceleration, and speeding during driving. This helps businesses or vehicle owners manage and train drivers, improving driving safety and fuel economy
Automatic Arming/Disarming
GPS tracker uses ACC detection to determine vehicle status. When the vehicle is turned off, the ACC signal is turned off, and the tracker may automatically enter the armed state. During this time, if the vehicle is vibrated or illegally moved, the tracker will trigger a vibration alarm or displacement alarm. When the vehicle is started, the ACC signal is turned on, and the tracker automatically disarms, resuming normal positioning and tracking functions
Optional Features – Bluetooth Communication / TTL Serial Port
Bluetooth communication is used for short-range data transmission with mobile phones or other devices, such as setting device parameters and downloading positioning data. It can also be used to connect Bluetooth sensors to expand the tracker’s functionality. The TTL serial port is a commonly used serial communication interface for short-range data transmission between devices. For example, it can be connected to the vehicle’s OBD port to obtain additional vehicle data or connect to other sensors for more extensive functionality
9-90V Wide Voltage Range
The wide voltage range allows the tracker to adapt to the power systems of various vehicles, eliminating the need to worry about voltage mismatches and improving the device’s versatility and stability

- Vibration Alarm: The vibration alarm can be set to armed via the platform or mobile app. The alarm has three levels, with level 1 being the most sensitive. In armed mode, even the slightest vibration from the vehicle will trigger a text message notification, alerting the owner of any unusual contact or movement.
- Displacement Alarm: When the vehicle is parked and in armed mode, any deviation from its intended route between points triggers a displacement alarm, sending an alarm signal to the GPS monitoring platform. This helps the owner detect any unusual vehicle movement and prevent theft or unauthorized removal.
- Overspeed Alarm: The accompanying backend management system allows you to set speed limit reminders. If the vehicle exceeds the speed limit, the driver will be prompted to slow down and receive an alert to the owner, ensuring driving safety and helping the owner monitor and manage the vehicle’s status.
- Low Battery Alert: When the device battery level drops below 10%, a low battery alarm is triggered, sending a signal to the GPS monitoring system to remind the user to charge or replace the device immediately to prevent positioning failure due to battery depletion.
- Multi-positioning: Utilizing the advanced GPS + Beidou dual-satellite positioning system, this system ensures accurate positioning in various environments. Additionally, some models may support Wi-Fi positioning and LBS base station positioning. For example, the GF21 combines GSM/GPRS networks with GPS satellite systems to achieve precise positioning and real-time monitoring of remote targets via SMS or the internet, enabling accurate location information in both urban and remote areas.
