Review Media
When a channel is configured with a video input, you’ll see the Review Media button located bottom-left of the main video display screen.
When you click on the Review Media button, it will open your system File Explorer window at the directory location where you’ve set your video recording, stills and framegrabs to be saved.

If you click the Review Media button, but have not yet set a folder for your recorded videos and framegrabs, you’ll get this message:
“You must select a directory for recording or stills in order to review its contents”
