File upload procedure When video/snapshot file is requested via SMS/GPRS command firstly the device checks if it has SD card inserted and if it has the requested video/snapshot in the SD card. The file is present, file upload is immediately triggered, otherwise the device checks if MDAS9 camera is connected to FMB640 and tries to download the file – file upload to the server starts only after the file was saved to FMBs SD card.
