Setting this will `false` will cause all cameras to load simultaneously when the `live` carousel is opened (or cause all cameras to load continually if both `lazy_load` and `preload` are `true`). This will result in a smoother carousel experience at a cost of (potentially) a substantial amount of continually streamed data. |
 | `lazy_unload` | `false` | :heavy_multiplication_x: | Whether or not to lazily **un**load lazyily-loaded cameras in the camera carousel, or just leave the camera paused. Setting this to `true` will cause cameras to be entirely unloaded when they are no longer visible (either because the carousel has scrolled past them, or because the document has been marked hidden/inactive by the browser). This will cause a reloading delay on revisiting that camera in the carousel but will save the streaming network resources that are otherwise consumed. This option has no effect if `lazy_load` is false. |
