Got an IP webcam but need to show it on your website? Cheap cameras frequently have crappy interfaces or login requirements. Using CURL and PHP, you can work around a number of issues while also hiding the username/password/port your webcam is actually on.
With a bit more work, you could even cache responses to provide better performance. This is next on my todo list, but contributions are welcome. Check out the Github repository for downloads and additional files!
