* On some hardware, a possible bug in the webcam firmware is triggered by Linux. Logitech is investigating the issue, and an explanation should hopefully be available next week (September 2006). As this doesn't occur when using Windows, we hope that a workaround will be possible. In the meantime, a patch is available to reset the webcam when a problem is detected. |

Applications
- The Webcam HowTo
- Ekiga -- Ekiga is a free Voice over IP phone allowing you to do free calls over the Internet. Ekiga is the first Open Source application to support both H.323 and SIP, as well as audio and video. Ekiga was formerly known as GnomeMeeting.
- motion -- motion-detection using a webcam
- sonic-snap -- webcam application specifically suited for the Sonix sn9c10x chip
- spook -- capture live video and audio and stream it over an IP network
- telak -- display remote or local pictures on your desktop
- vgrabbj -- grabs a image from a camera and puts it in jpg/png format
- Videoview & Device Debugger -- applications suited for some drivers present in the Linux kernel. Videoview supports the USB Video Class standard.
- webcam -- captures images and uploads them to a Web-Server via ftp or ssh in a endless loop
Resources
- Video for Linux resources -- see Video: Security / Webcams / Monitoring
- For USB webcams, see also video devices in the USB device overview database
UVC webcams
Do you have USB 2.0 controllers on your notebook and desktop? If so, you could benefit from higher resolutions with the Logitech Quickam for Notebooks Pro, Quickcam Fusion and Quickcam Orbit MP. All those webcams are 1.3MP devices and are supported by the linux-uvc driver. Note that the Quickcam for Notebooks Deluxe doesn't fall in that category; it's supported by the spca5xx driver.
Those 3 webcams also work in USB 1.1 mode, but are then limited to 640x480. In that case, you could go for the Quickcam Pro 5000, which is a 640x480 device supported by the linux-uvc driver.
UVC webcams are well supported, but you must be aware of a few issues.
- The linux-uvc driver is V4L2-only. This means applications which support V4L1 only will not work. V4L1 is officially deprecated, and have been removed from the kernel recently, so most drivers have or will switch to V4L2 anyway.
- The 4 webcams mentioned above compress images in MJPEG for resolutions up to 960x720. This means that applications must be able to decompress MJPEG streams to use the webcam at lower resolutions. Ekiga supports MJPEG compression.
