| `controls` | | Configuration for the `live` view controls. See [`controls`](#controls). |
| `display` | | Controls whether to show a single or grid `live` view. See [`display`](#display). |
| `draggable` | `true` | Whether or not the live carousel can be dragged left or right, via touch/swipe and mouse dragging. |
| `lazy_load` | `true` | Whether or not to lazily load cameras in the camera carousel. 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_load` | `true` | Whether or not to lazily load cameras in the camera carousel. Setting this to `false` will cause all cameras to load simultaneously when the `live` carousel is opened (or cause all cameras to load continually if `preload` is also `true`). This will result in a smoother carousel experience at a cost of (potentially) a substantial amount of continually streamed data. |
| `lazy_unload` | `[]` | A list of conditions in which live camera feeds are unloaded. `unselected` will unload a camera when it is not visible in the carousel/grid and `hidden` will unload a camera when the browser itself is minimized or the browser tab changes. An empty list (`[]`, the default) will never automatically unload a stream once loaded unless the user navigates away entirely, so that it's always instantly visible on carousel scroll. Once unloaded, subsequently revisiting the camera will cause a reloading delay. Some live providers (e.g. `webrtc-card`) implement their own lazy unloading independently which may occur regardless of the value of this setting. |
| `microphone` | | See [`microphone`](#microphone). |
| `preload` | `false` | Whether or not to preload the live view. Preloading causes the live view to render in the background regardless of what view is actually shown, so it's instantly available when requested. This consumes additional network/CPU resources continually. |
| `preload` | `false` | Whether or not to preload the live view. Preloading causes the live view to render in the background regardless of what view is actually shown, so it's instantly available when requested. The currently-selected camera's media is loaded in the background; other cameras follow the `lazy_load` setting (set `lazy_load: false` to preload them all). This consumes additional network/CPU resources continually. |
| `show_image_during_load` | `true` | If `true`, during the initial stream load, the `image` live provider will be shown instead of the loading video stream. This still image will auto-refresh and is replaced with the live stream once loaded. |
| `transition_effect` | `slide` | Effect to apply as a transition between live cameras. Accepted values: `slide` or `none`. |
| `zoomable` | `true` | Whether or not the live carousel can be zoomed and panned, via touch/pinch and mouse scroll wheel with `ctrl` held. |
