The free cloud recording offered to everyone is your camera will take a 12 second clip then will have to wait a cool down period before taking another video event. These are accessable in the event tab, just like camplus videos. Camplus saves videos for the duration of the motion to the cloud, which is also viewable in the event tab and signified as being labeled with the video length.
The local recording ( SD card) and cloud recordings (free and camplus) are completely Independant of each other. You can have one, both or neither.
Its easier to scrub through and save large amount of video that way, but not the only way to view. There is the playback link off the live view.
