I need to set up a webcam to act as a security monitor for a one-off event of around 10 hours. My key requirement is that the video feed is streaming to the Internet and being recorded to the Internet in real-time. Recording in real-time to the Internet is important, as the camera will be in a relatively unsecure location where it would be possible for someone to access the local computer in real-time and cancel/delete any local and/or delayed recording, and there won't necessarily be anybody monitoring the live stream as it happens.
I'm running Ubuntu. What's a quick way to get this setup? Is there a web service that meets these requirements, or is it easy to e.g. configure VLC to do this?
