Webcam: Webcam
This is where you can view and control any
connected UVC (USB Video Class) webcams.
For a list of UVC compliant webcams see here:
http://linux-uvc.berlios.de/#devices
Video is streamed from these devices in
M-JPEG format, and can be view though the
web interface, or any compatible M-JPEG
viewer (such as VLC). Webcams that support
pan/tilt can be controlled via the web
interface. Multiple frame rates and resolutions
are supported. To get started, plug in the
webcam and the interface will be initialized.
If the video stream is to be exported over the
internet, it is recommended that the password be enabled. However, it must be noted that this is a simple HTTP
authentication, which is sent unencrypted, and thus not highly secure.
If prompted for the webcam password, the username is ‘webcam’.
