Tnx alot wpte, this is much easy to folow for me, maybe others too.
Restarting manually the process step on my nerves ^^.
UPDATE: in the beta firmware on http://wl500g.googlecode.com you can use the refresh-time in the web admin with the same end result as in this how-to. Might be even easier :-)
Well, I decided to make a little how to for simple webcamming via the admin-interface.
Everybody knows that rcamd isn't really the best way to stream your webcam since it uses all your cpu... but I have a solution for that
Also, not every motion detection program seems to work with webcams supported by the router, but rcamd usually does.
allright, here we go:
Step 1
First of all we need a compatible webcam, you can look in the forums for a good one that works. http://wl500g.info/showthread.php?t=...Busb%5D+webcam
I myself have the Logitech Quickcam 4000 pro connected.
So next thing we do is connect it to the router, and then configure the settings in the webadmin interface.
you can make it look similair like this if you want.
note that the webcam driver should be loaded automatically, so it doesn't matter what you select.
Just save the settings and reboot the device.
Step 2
Now log in via putty into your router.
make sure you have putty maximized so your screen is completely filled with putty
issue the command
orps
to see the list of active processesps axf
in that list of processes you will find something similair to this:
note that it will appear 3 times in the list, if it does not, your webcam is probably not supported!rcamd -p 7777 -s 0 -z MET-1METDST,M3.5.0/2,M10.5.0/3 -a 0 -t 0 -r 0 -f 640x480 -m 100 -c 100
just select this piece with your mouse so it'll become white:
now just open up notepad and press control + c to paste it into notepad.
Now make sure, that everytime I call my copied rcamd process, you use your own copied version, as it might differ!
Step 3
Now we will do some magic
rcamd -p 7777 -s 0 -z MET-1METDST,M3.5.0/2,M10.5.0/3 -a 0 -t 0 -r 0 -f 640x480 -m 100 -c 100
the bold piece in this code is importand, you need to change it.
-s is an option that allows you to lower the framerate, so also the cpu usage
at this time it says 0, so it will capture an unlimited frames per second, till the cpu or the webcam can't handle any faster, we are about to change that.
now if we change the 0 into a 4, the webcam will send every 4 seconds 1 image. so that will give you a framerate of 0.25fps
no worries, it won't show up as only 1/4 of your screen
You can adjust this number to your own wish, but I like the 4, because you won't notice the webcam is runnig on the performance
Now also place a "&" behind the whole line, and end up having something similair to this:
Step 4rcamd -p 7777 -s 4 -z MET-1METDST,M3.5.0/2,M10.5.0/3 -a 0 -t 0 -r 0 -f 640x480 -m 100 -c 100 &
now we are still in putty will make the final hand to the evil process:
Now paste somewhere in this file the following:vi /tmp/local/sbin/post-mount
after this lines, paste your own rcamd copy!#Restart rcamd with proper settings
killall rcamd
sleep 3
so it will look like this:
now save the file and:#Restart rcamd with proper settings
killall rcamd
sleep 3
rcamd -p 7777 -s 4 -z MET-1METDST,M3.5.0/2,M10.5.0/3 -a 0 -t 0 -r 0 -f 640x480 -m 100 -c 100 &
now to be sure it works, just issue "ps" to look at the cpu usage, and check if rcamd is using hardly any cpuflashfs save && flashfs commit && flashfs enable && reboot
Final step
YES! now you can finally watch your webcam!
huh? what not working?
probably you have problems with the activeX webcam program on the webcam site.
if you don't know what the site is...
http://yourasusip:7776
As far as I know the active X version only works with IE
first go to control panel of windows, then to internet options:
go to the security tab
select trusted websites
lower the the security level to lowest
click on websites to add a new website to be trusted
enter your asus ip adress or domain to add into the trusted websites
make sure you have https selection off, otherwise you won't be able to add something.
now apply everything and refresh your webcam page
just install the activeX, and when promted if you want to run the object on your pc, answer yes
and tata, here is your webcam feed
Be sure the time changes in the picture
you probably need to adjust the focus of the webcam too, for a sharp image, just turn around the lens wheel (with most webcams)
now if you use the activeX version, yo can left click and right click on the image.
left click will capture a screenshot and save it to somewhere on your disk
right click will capture a movie to your harddisk
I hope this works for ppl

Tnx alot wpte, this is much easy to folow for me, maybe others too.

haha, yes I know, but if you don't kill the original process...
you hardly will be able to do anything
oh and the "&" is most likely to be the most importand, otherwise it'll stop working after an hour of 2
I also corrected a little mistake in the how-to, didn't change anything to the scripts
I hope it's all clear, and I didn't make a mess of it
Sorry for this noobquestion - but:
After testing all my webcams i found just one which is "working": an old Creative Webcam III
Works like a charm - but with ONE problem: I need to plug it in when the device is booted completely... otherwise i have no rcamd process except of rcamdmain.
I can fix it by pulling the cam out of the usb jack and replugging it - which is not a good solution for a fixed installation of course
So is there *any* way to re-initate that USBdriver / device recognition / init / whatever without hands on the hardware?
Any hints are highly appreciated....
This is what i got: wl-500gp router, latest oleg firmware, philips webcam.
This is what i've tried:
1. webcam (rcamd) started from administration page. works, but at certain point it crashes
2. rcamd killed and started in post-boot (for slower framerate). it crashes also
3. i've installed motion, but i didn't got it started. i've started the driver but it didn't worked
Please, can someone make a tutorial for using webcam as a surveilance cam...?? I want to get mails with pictures if something is moving in front of the webcam.
I've managed to make rcamd send mail, but it doesn't use the server i've set...and it crashes.
I've read that Palantir works simply as streaming server. It doesn't send mail alerts, and i did'n tried to install it.
Please help. Thanks
well... does your webcam work with rcamd?
otherwise different software won't work either most likely... (drivers maybe don't support your webcam)
anyway...
sourceforge: http://sourceforge.net/search/?words...ewfilter=Apply
google: http://www.linux.com/news/hardware/p...a-linux-webcam
maybe you find some program that is usefull for you, then you might be able to compile it yourself... or I'll give it a go
Hi Wpte & thanks for the how to -
Have been using this for a while but would now like to backup the images that are taken.
I am assuming at the moment that display.jpg is just overwritten with every refresh, but I would like to store these images instead.
Is this possible - is there a setting in rcamd that I can use or could I create a script to copy/move display.jpg every time it is modified.
Thanks in advance for any help with this.
** BTW: the reason I am doing this is I want to create a stop-motion video of a plant growing ***
I can see that display.jpg is symlinked to /var/tmp/display.jpg and in turn this file is dynamically syslinked to record0.jpg - record5.jpg
this seems to be the last 6 images - is there a way to change the symlinks to the usb drive and to set it to record the last 100 images instead of the last 5??

Hey velcrow,
I made this little script here:
it's quite self explainingCode:#!/bin/sh #Seconds of sleep before doing another copy SLEEP=15 #Source JPG file that needs to be copied. SOURCEJPG=/var/tmp/display.jpg #Output folder which will contain all the JPG files OUTPUT=/mnt/webcamimages #Choose between a counting name or date #COUNTING or DATE MODE=COUNTING COUNT=0 if [ $MODE="COUNTING" ]; then while /bin/true; do /bin/cp $SOURCEJPG $OUTPUT/$COUNT.jpg COUNT=$(($COUNT + 1)) /bin/sleep $SLEEP done fi else if [ $MODE="DATE" ]; then while /bin/true; do /bin/cp $SOURCEJPG $OUTPUT/img\_$(/bin/date '+%Y%m%d_%H%M%S').jpg /bin/sleep $SLEEP done fi
unfortunately my plan for saving it by date+time in the filename didn't worked out too well, since I'm not too familiar with the bash syntax.
however the counting filename works fantastic
just edit it to personal preferences...
and execute it like this:
so you can shut down your pc while the router keeps the images rolling in../sbin/webcammon.sh &
The limitation so far is, that I have no idea what the maximum number for count is... probably around 32000 or 65000 keep an eye on it
I hope you find it usefull, and maybe someone can fix my horrible mistake of the date saving thing
EDIT:
Thanks to EdP the date and time thing is working now
a little example of a result:

Hi,
Here's a suggestion on how to fix the date thing:
replace that cp sentence by the following:
Or something similar. That way your files will be namedCode:/bin/cp $SOURCEJPG $OUTPUT/img\_$(/bin/date '+%Y%m%d_%H%M%S').jpg
/mnt/webcamimages/img_20090723_193943.jpg (etc.)
Ýou're very welcome. It's not much different from sh, ksh, even pretty similar to csh and tcsh which were popular back in the day
Qbasic *cough* *cough*
Be careful, or you'll sound like a barbarian
Tcsh should be much to your liking then. OK back on topic I guess ...
hey don't underestimate the sheer power of qbasic
anyway, this is the latest version of the script, which gives a harddrive time to spin down by temporary storing the files in /tmp/imag
I tested it, and it worked great
here it is:
another example of the script result:Code:#!/bin/sh #Seconds of sleep before doing another copy SLEEP=15 #Source JPG file that needs to be copied. SOURCEJPG=/var/tmp/display.jpg #Output folder which will contain all the JPG files OUTPUT=/mnt/webcamimages #Choose between a counting name or date(not working yet) #COUNTING or DATE MODE=COUNTING #Optimize for Harddrive spindown? (TRUE or FALSE) OPTIMIZE=TRUE #Save files up to ... in flash #The max size of an jpeg file is about 65KB so 65*150=9,75MB wich leaves enough of the ~14,5MB flash. #And if the images are taken every 15sec you will leave the hdd untouched for 37min! #Please keep in mind that if you set it too high there won't be memory left in /tmp FLASHSAVE=150 #Flash directory to save in FLASHDIR=/tmp/imag COUNT=0 if [ $OPTIMIZE="TRUE" ]; then if ( [ ! -d $FLASHDIR ] ); then /bin/mkdir $FLASHDIR fi /bin/rm $FLASHDIR/* if [ $MODE="COUNTING" ]; then while /bin/true; do for i in $(seq 1 $FLASHSAVE); do /bin/cp $SOURCEJPG $FLASHDIR/$COUNT.jpg COUNT=$(($COUNT + 1)) /bin/sleep $SLEEP done /bin/cp $FLASHDIR/* $OUTPUT/ /bin/rm $FLASHDIR/* done fi else if [ $MODE="DATE" ]; then while /bin/true; do for i in $(seq 1 $FLASHSAVE); do /bin/cp $SOURCEJPG $FLASHDIR/img\_$(/bin/date '+%Y%m%d_%H%M%S').jpg /bin/sleep $SLEEP done /bin/cp $FLASHDIR/* $OUTPUT/ /bin/rm $FLASHDIR/* done fi fi else if [ $OPTIMIZE="FALSE" ]; then if [ $MODE="COUNTING" ]; then while /bin/true; do /bin/cp $SOURCEJPG $OUTPUT/$COUNT.jpg COUNT=$(($COUNT + 1)) /bin/sleep $SLEEP done fi else if [ $MODE="DATE" ]; then while /bin/true; do /bin/cp $SOURCEJPG $OUTPUT/img\_$(/bin/date '+%Y%m%d_%H%M%S').jpg /bin/sleep $SLEEP done fi fi

Thanks wpte & Edp -
This is great, I spent some time trying the rcamd commands but with no luck...
what does the -r setting do?
and why does it record 6 files - record0.jpg - record5.jpg?Code:rcamd -p 7777 -s 4 -z MET-1METDST,M3.5.0/2,M10.5.0/3 -a 0 -t 0 -r 0 -f 640x480 -m 100 -c 100 &
Really appreciate this, as there was no chance of me solving this in such an elegant way
