Lw4g 4d Lynkworld

LW4G-4D

Product Introduction

Dimensions: 90.6 (length) x 68 (width) x 20 (thickness) mm

Weight: 68g

Positioning Methods: GPS/BDS/LBS

 

Product Introduction
Positioning Information Upload: Uploads positioning information, such as longitude and latitude, according to the interval configuration.

Power On/Off Status: Each uploaded data packet contains the power on status.

External Power Cut Alarm: When the GPS tracker detects that the external voltage is too low, it will be reported with the low voltage alarm.

Remote Oil/Circuit Cut-off: Sends commands remotely to turn on/off oil/circuit (relay required).

Low Consumption Alarm/Low Battery Alarm: When the GPS tracker detects that the external voltage is not lower than 9V, it will be reported with the low consumption alarm.

Automatic SIM Card Identification: Automatically identifies the SIM card and uploads its information.

 

Message Buffer: Positioning data will be stored in the buffer when they are in blind spots of the network, and the data will be uploaded later when the tracker connects to the network. Buffer Memory: 5000

Mileage Statistics: Calculates total mileage.

Jammer Algorithm: Intelligent identification of surrounding interference environment.

Power Saving Mode: Switches to standby mode when the vehicle is stopped. 

OTA: Supports OTA.

Custom Protocol: Multiple protocols supported.
