Product Functions Position Tracking
| Function | Description |
| Real-time tracking | After sending a command, you can query the current device location from the platform or your mobile phone. |
| Tracking by time interval | After you set the time interval, the device will report its location information to the platform or mobile phone at the preset time interval. |
| Tracking by distance | After you set the distance, the device will report its location information to the platform based on the preset distance. |
| Cornering report | Set the cornering angle. When the driving angle is greater than the preset value, the device will report its location information. This report is used to make the driving route smoother when no data is sent at the preset time interval or distance interval while the vehicle corners. |
Alerts
| Function | Description |
| External power supply cut-off alert | When the device is removed from the OBD connector, an alert will be reported to the platform or be notified to the user. |
| Speeding | You can set the maximum speed threshold by using the platform, Meitrack Manager software or SMS. When the driving speed exceeds the preset value, an alert will be sent. |
| Geo-fence | With a coordinate and radius, you can set a circular geo-fence. When the vehicle enters or exits the preset geo-fence, an alert will be reported to the platform or be notified to the user by SMS. A maximum of eight circular geo-fences can be set. |
| SOS alert | When the SOS button is pressed, an alert will be sent. |
| Low battery alert for the external power supply | When the voltage of the external power supply is lower than 11.4 V, an alert will be sent. |
| Device status alert | When the device is powered on or powered off, a device status alert will be sent. When the internal battery power is low, a low battery alert will be sent. |
| Harsh acceleration/braking alert | When the driving speed exceeds the preset harsh acceleration/braking threshold, an alert will be sent. The TC68L supports this function because it can obtain OBD data. However, the TC68SL does not support this function. |
Other Functions
| Function | Description |
| Over-the-Air (OTA) update | Update the device firmware by OTA. |
| GPS log | When the GPS is valid, the device will record the driving routes at the preset time interval. You can use Meitrack Manager software to read these records. A maximum of 130,000 records can be stored. |
| GPS + LBS positioning | When a valid GPS signal cannot be received, the GSM base station will be used for assisted positioning to ensure that the vehicle can be located at any time. |
| GPS blind spot report | When the vehicle enters or exits an area without GPS signal, the device will send a report to the platform. |
| Auto data storage in a GSM blind spot/Data resending | When data fails to be sent to the platform in a GSM blind spot, the data will be automatically stored. When the GSM becomes valid, the data will be automatically sent to the platform. The built-in 8 MB flash memory can store 8,192 pieces of GPRS data and 256 SMS messages. |
| Mileage report | All the GPRS data contains the vehicle mileage. For the first use, you can modify the default mileage. |
| Maintenance report | You can set the maintenance mileage and time by using the platform. When the vehicle maintenance mileage or time reaches the preset value, the device will send a maintenance alert. |
| External power protection | When the device detects that the voltage of the external power supply is lower than the rated voltage and the device stops moving, it will automatically enter the deep sleep mode. |
| WiFi function (optional) | The device supports the 2.4 GHz WiFi hotspot function, and a maximum of eight WiFi networks can be connected. You can use Meitrack Manager software to configure the WiFi function. |
