Here's my /etc/camE.conf - this captures a frame every 5 seconds and ftps it
off to another server:
[ftp]
host = REMOTEHOST
user = USER
pass = PASS
dir = /home/webcam
file = webcam1.jpg
tmp = imageup1.jpg
local = 0
passive = 1
[grab]
device = /dev/video0
width = 640
height = 480
delay = 5
input = webcam
quality = 80
title_text = 1
text = %d-%m-%Y %H:%M:%S
ttf_dir = /usr/share/fonts/bitstream-vera/
text_font=VeraMoBd/7
title_font=VeraMoBd/8
framerate = 1
pwc_wb_mode = outdoor
# image settings (0-100) defaults are 50
colour = 60
brightness = 50
contrast = 50
hue = 50
whiteness = 50
(obviously REMOTEHOST, USER and PASS have been changed for my security!)
and also here's my modified /etc/init.d/camE script:
#!/bin/bash
#
# camE This shell script enables the startup of camE
#
# Author: Seth Vidal <skvidal@xxxxxxxxxxxx>
# modified from the yum startup script by Tony
#
# chkconfig: 345 98 02
#
# description: Enable startup of camE, a frame grabber & ftp tool
# processname: camE
# config: /etc/camE.conf
#
# source function library
. /etc/rc.d/init.d/functions
lockfile=/var/lock/subsys/camE
RETVAL=0
start() {
echo -n $"Enabling webcam: "
/usr/local/bin/setpwc -x
/usr/bin/camE -c /etc/camE.conf >/dev/null 2>/dev/null &
touch "$lockfile" && success || failure
RETVAL=$?
echo
}
stop() {
echo -n $"Disabling webcam: "
killall /usr/bin/camE
rm -f "$lockfile" && success || failure
RETVAL=$?
echo
}
restart() {
stop
start
}
case "$1" in
start)
start
;;

;;
condrestart)
[ -f "$lockfile" ] && restart
;;
status)
if [ -f $lockfile ]; then
echo $"Webcam is enabled."
RETVAL=0
else
echo $"Webcam is disabled."
RETVAL=3
fi
;;
*)
echo $"Usage: $0
{start|stop|status|restart|reload|force-reload|condrestart}"
exit 1
esac
exit $RETVAL
You'll probably need to delete the setpwc line, since that's an extra tool
I've copied in as a binary from a previous incarnation of my box, and I'm
not quite sure where to get it from at the moment. It just resets the colour
balance of the webcam, and may not be relevant for your model anyhow.
After these 2 files are in place, it's just a service like any other, so use
'chkconfig camE on' and 'service camE start'. Keep an eye on your
/var/log/messages, if the camera is dropping frames regularly then the
logfile can get big.
