Multi-Cam Timeline Dynamic Display
With a 4-cam group. Scrub across the Timeline and drop. Events now display dynamically, expanding and contracting to show active-cams-only, at maximum size, as time unfolds.
4 active cams: 4-up thumbs
3 active cams: 1 large and 2 thumbs
2 active cams: 2 large
1 active cam: 1 large
Pretty slick if you have a lot of action unfolding around a property perimeter.
