I built a live webcam atlas with 7,000+ streams from 100+ countries — here's what watching the world taught me

说明与用途

Cam-World 聚合了 7000+ 个来自 100+ 国家/地区的公共摄像头，自动检查摄像头可用性，并提供交互式全球地图，帮助用户快速找到可靠的直播流。

问题

Aggregators often show unreliable thumbnails and lack uptime info, making it hard for users to find working live webcams.

结果

Users can now find reliable live webcams quickly, with transparent uptime data and a global map interface, improving user satisfaction and engagement.

工作流

• 1. Crawl public webcam URLs from various sources.
• 2. Store stream metadata (location, tags, language).
• 3. Periodically ping each stream to determine online status.
• 4. Aggregate uptime data into 24‑hour and 30‑day timelines.
• 5. Render a dark globe map with green dots for live cameras.
• 6. Provide search by name, city, country, tags, and themed collections.
• 7. Offer sorting by distance and display live/offline badges on cards.

证据

Aggregators usually show you a thumbnail and pray. We check every camera automatically and show a statistics widget: the last 24 hours and 30 days as color‑coded slots (online / outage / offline / no data) plus an uptime percentage.

The planet has a rhythm. Webcams go online with the morning sun, and the "online" wave rolls west around the clock.
