Step 1 From main menu->Setting->Storage->FTP, enter FTP interface. See Figure 4-193. Step 2 Select the Enable check box to enable FTP function. Select FTP type. FTP transmits data with clear text mode and SFTP transmits data with encrypted mode. SFTP is recommended. Step 3 Set parameters. Here you can input FTP server address, port and remote directory. When remote directory is null, system automatically creates folders according to the IP, time and channel.  IP address: The host IP you have installed the FTP server.  Port: The default SFTP port number is 22 and the default FTP port number is 21.
191  User name/Password: The account for you to access the FTP server.  Remote directory: The folder you created under the root path of the FTP according to the corresponding rule.  If there is no remote directory, system can auto create different directories according to the IP, time and channel.  If there is remote directory, system can create corresponding folder under the FTP root path and then create different folders according to IP address, time and channel.  File length: File length is upload file length. When setup is larger than the actual file length, system will upload the whole file. When setup here is smaller than the actual file length, system only uploads the set length and auto ignore the left section. When interval value is 0, system uploads all corresponding files.  Image upload interval: It is the image upload interval. If the image upload interval is larger than the image snapshot frequency, system just uploads the lasted image.  If the image interval is 5 seconds and the snapshot frequency is 2 seconds, system will send out the latest image at the buffer at 5 seconds.  If the image upload interval is smaller than the snapshot frequency, system will upload at the snapshot frequency. For example, if the image interval is 5 seconds and the snapshot frequency is 10 seconds, system will send out the image at 10 seconds.  From main menu->Setting->Camera->Encode->Snapshot to set snapshot frequency.  Channel: Select a channel from the dropdown list and then set week, period and record type.  Week day/Period: Please select from the dropdown list and for each day, you can set two periods.  Type: Please select uploaded record type (Alarm/intelligent/motion detect/regular).
