    • Click the clear network log icon
  • In Cloudvue Save the desired Clip
    • Items will begin to appear in the Dev Tools network log
  • Hover over each Network Log entry to reveal the full url
  • You want the one that begins with “https://archive.cloudvue.com/camera”
    • Right click the log entry
    • Expand Copy
    • Choose copy link address
  • Open a new tab in Chrome
    • Paste the copied url into the address bar
    • It will look similar to this
