Your library
Cameras, walls and settings are stored in this browser (IndexedDB). Nothing is sent anywhere except the requests to the cameras and sources you load. Use Settings → Backup to move a library between browsers.
Feed types
- Still image — reloaded on a timer; Overlook keeps recent frames so you can rewind and play them back.
- MJPEG — continuous motion-JPEG streams from IP cameras.
- HLS video — .m3u8 live streams, played natively or with the built-in HLS player.
- YouTube — video, live, or a channel's current live stream.
- Web page embed — players such as Windy's; some sites refuse to be embedded.
- Link only — a preview with a button to open the publisher's page.
Map and filters
Drag to pan, scroll or pinch to zoom. Click a state to filter to it (click again to clear). Click a cluster to zoom in. Colors show category; hollow dots are cameras that failed to load. Under More filters, pick an interstate to see every camera along it; routes are read from camera names such as “I-77 at Exit 82”.
Walls
Drag cameras from the list onto a view, or click an empty view and then a camera. Drag a view's title bar onto another to swap. Cycle rotates through everything in the current filter.
Checking cameras
Check loads each still image with a timeout and marks it working or not loading. Video and embedded feeds often can't be tested from a web page; those are marked “can't verify”. Cameras also update their status as you watch them.
Fall colors
The Fall colors chip shows cameras overlooking foliage: the curated foliage cams plus any park, mountain or scenic camera in well-known leaf-peeping areas. “Load fall cams” adds the curated set and, if they aren’t loaded yet, the National Park Service cameras. Most curated cams are YouTube live streams; a stream that was restarted by its owner gets a new address, so if one ends, use Open on YouTube to find the owner’s current stream.
Finding more cameras
Add cameras → “Search catalogs” looks through ArcGIS Online and the Socrata open-data network for public camera layers by topic and state: highways, state parks, national parks, mountains, beaches. Load one to try it; tick “Remember” to keep it with the built-in layers so it refreshes with “Load every no-key source”.
When an import fails
Some servers block requests from web pages (CORS). Open the source URL in a new tab, save the response, and import the saved file; or set a CORS proxy in Settings. If you open Overlook from a website over https, plain-http cameras will be blocked by the browser — open the file locally instead.
YouTube embeds
YouTube may refuse to play embeds on pages opened straight from disk. If a YouTube view shows an error, use “Open on YouTube”, or serve the file from a local web server.
