When “On” is selected for both the alarm image transmission function and the FTP periodic image transmission function, the alarm image transmission function will be given priority over the FTP periodic image transmission function. Also, when “On” is selected for the “FTP transmission retry” FTP setting (→
[FTP transmission retry]), alarm images will be retransmitted if there is an FTP transmission failure. Therefore, if there is continuous retransmission due to network problems or other factors, periodic transmission will not be performed and images that fail to be transmitted with the FTP periodic image transmission will not be saved to an SD memory card.
