Hello,
If you are using the VSS software and have your IP or web cam connected, this should continue uploading as long as you have the software running. You will need to be sure that your computer is not set to a timed sleep mode, as this will disable the software from running. Your computer will have an option to set the sleep mode to 'never' in which case you the software should never automatically stop.
Please make sure to install the latest version of the software from our website and email support@cameraftp.com if you have any continued difficulties.
