Most Foscam cameras will limit video files to only MKV format, which is not supported by most browsers. This might give you the thinking that you are dealing with corrupt files when in fact they are just not being played correctly. That being said, sinc you're now using VSS, all video files are converted to .mp4 so they can easily be played-back on all web browsers/devices. Quickly testing your uploaded materials, I was indeed able to playback that content without any issue.
Please reach out to us directly at firstname.lastname@example.org with more detailed information about where you are getting stuck so that we can support you through any misunderstandings; because everything with your account seemsto be fine.
