Once the sensor detects a distracted or drowsy driver, it will immediately send out a sharp and loud alarm. At the same time, the sensor’s camera will take a picture.
If the fatigue sensor is enabled in the configuration, it will send the gathered data (file name, source ID and alert ID) to the tracking device.
If the tracking device has an SD card, the pictures will be stored in the card and sent to a server upon request. If the fatigue sensor folder on the SD card is full, the oldest picture will be overwritten.
If the folder is full and there are no pictures on the card, the taken picture will be discarded.
After receiving the pictures, the server can then send a request to delete them from the SD card in order to conserve the memory. A maximum of 2000 pictures can be stored in the fatigue sensor folder.
