Since you mentioned previously using Cam v2 and Cam v3, you’ve probably noticed that the Cam v4 UI has a significant difference. When you’re viewing the Live Stream screen of a Cam v4, you should see a SD Card icon in the control strip below the viewer pane. You can tap that to access a vertically-scrolling timeline of your camera’s microSD recordings. If you have recording set to Continuous, then you’ll see a solid green vertical line on the right of the timeline; if recording is set to Events Only, then the green line will be broken (with gaps where the camera wasn’t recording to microSD).
