camE is a Webcam grabber designed for video4linux devices. It is based on the xawtv webcam app, but extended to use imlib2 for applying antialised, blended truetype fonts to the image before upload. A large number of new options have been added including scp support (in addition to ftp), image archiving, and much more. It runs as a daemon and needs no X connection to operate.
The HP OfficeJet Linux driver provides printing, scanning, and photo-card access support for most Hewlett-Packard multi-function peripherals connected to a parallel port, USB port, or LAN via selected HP JetDirect print servers. Additional applications are provided to view the contents of the front-panel LCD and to access other control and status features of the device.
motion uses a video4linux device for detecting movement. It makes snapshots of the movement which can be converted to MPEG movies in realtime (or later for low CPU usage), making it usable as an observation or security system. It can take actions like sending out email and SMS messages when detecting motion.
