USB Webcam on QNAP's

Alright, here is my first blogpost.

No garanties, proceed with caution and at your own risc.

A while ago I started wondering what the power consumption would be
of my home server / media center. A dual core 3 Ghz, 300watts.
Needless to say, it turned out to be expensive. About 600 euros a year
expensive.

This meant radical measurements. I bought a Apple TV 2, jailbroke it
and installed xmbc on it. Only 10 watts when in use, magnificent. As
far as mediacenters go that is, with it's 8 gb of storage it does a lousy
job as file server. :-)

That's where the QNAP comes in. Since I already had enough
harddrives, it felt a bit stupid to buy another one. Luckily there was
a NAS available with just a sata drive slot.

QNAP TS-110, with its arm chipset the device uses only 7 watts when
in use. 5 when idle. Nice. And even better, it's Linux powered with ssh
access and even a package manager.

You can even hook up security cameras to it, according to the box
that is. It turns out, the little bugger only likes those expensive ip cams.

But hea, that's not going to ruin my day. Lets face it, the QNAP has
usb, linux, memory, harddrive, and who knows what else. So I started
searching the web, went into freak mode, and succeeded. A QNAP TS-110
that also has usb webcam support for security became a fact.

Allow me to talk you trough it.

In those steps i assume that you have some know-how of Linux,
command line stuff. And already know how to log in
you own QNAP through ssh.

Here we go; log in to your machine using your favorite ssh client.

install some required software:

ipkg install nano gcc make automake ncurses ncursesw wget w3cam motion

Browse to your harddrive: note, you QNAP may have a different location for this!

cd /share/HDA_DATA

Create a folder to work from, for example, "cam"

mkdir cam
cd cam

Get sourcefiles for your QNAP:

wget http://resources.qnap.com/Storage/tsd/QNAP_GPL_3.3.3-20100928.tar.gz

Get Linux kernel source:

wget ftp://ftp.jp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.33.2.tar.gz

Untar those files:

tar xzvf QNAP_GPL_3.3.3-20100928.tar.gz
tar xzvf linux-2.6.33.2.tar.gz

browse to the folder that corrospondents to your QNAP:

cd GPL_TS/kernel_cfg
ls



I own a TS-110:

cd TS-110


Copy the kernel config file that corrosponds to your kernel version (type uname -r to find out which one you have) to the kernel source files

ls
uname -r
2.6.33.2

cp ./linux-2.6.33.2-arm.cfg ../../../linux-2.6.33.2/.config


Let's browse to that folder:

cd ../../../linux-2.6.33.2/


Now let's edit this standard config file from QNAP to get our webcam support:

nano ./.config


Search the document for the following line:

# CONFIG_MEDIA_SUPPORT is not set


and change it into:

CONFIG_MEDIA_SUPPORT=m



Put the next couple of lines under it, this way it'll build a whole lot of modules.
Note: It's also possible to save and exit now, the config tool will ask you then which module
to build. If it doesn't ask you for the pwc driver, edit the .config file again and add
CONFIG_USB_PWC=m save and run the config tool again. Unless you don't need the pwc driver for your cam.

Save by pressing CTRL+O, exit by pressing CTRL+X

Let's make some symlinks, so the setup program can do it's business:

ln -s /opt/lib/libncurses.so /lib/libncurses.so
ln -s /opt/lib/libncurses.so.5 /lib/libncurses.so.5
ln -s /opt/lib/libncurses.so.5.7 /lib/libncurses.so.5.7
ln -s /opt/lib/libncursesw.so /lib/libncursesw.so
ln -s /opt/lib/libncursesw.so.5 /lib/libncursesw.so.5
ln -s /opt/lib/libncursesw.so.7 /lib/libncursesw.so.7


Run the kernel configtool:

make oldconfig


Note when questions are asked, just hit return, default answer is usually right.

Let's build the modules!

make modules



Grab some coffee, call a friend, or just be patienced
When completed continue by creating the device:

mknod /dev/video0 c 81 0
ln -s /dev/video0 /dev/video
chmod 666 /dev/video*


Let's find out which driver we need for our cam:

lsusb

Bus 001 Device 003: ID 046d:08b2 Logitech, Inc. QuickCam Pro 4000
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


Grab a browser, go to your favorite search site and put something like:
046d:08b2 module
The search results will give you a pretty good idea which module to use. I need the module pwc, first load some video for linux modules:

insmod drivers/media/video/v4l1-compat.ko
insmod drivers/media/video/videodev.ko
insmod drivers/media/video/v4l2-common.ko
insmod drivers/media/video/v4l2-int-device.ko
insmod drivers/media/video/videobuf-core.ko


For pwc: ( size=cif fps=5 power_save=1 is needed for my logitech, not sure if everybody needs it, try on error :-)

insmod drivers/media/video/pwc/pwc.ko size=cif fps=5 power_save=1


For gspca:

insmod drivers/media/video/gspca/gspca_main.ko


and then insmod the needed subdriver, as example (for some old Logitechs I believe):

insmod drivers/media/video/gspca/gspca_spca561.ko


For uvc:

insmod drivers/media/video/uvc/uvcvideo.ko


Once loaded check dmesg:

dmesg
Linux video capture interface: v2.00
pwc: Philips webcam module version 10.0.13 loaded.
pwc: Supports Philips PCA645/646, PCVC675/680/690, PCVC720[40]/730/740/750 & PCVC830/840.
pwc: Also supports the Askey VC010, various Logitech Quickcams, Samsung MPC-C10 and MPC-C30,
pwc: the Creative WebCam 5 & Pro Ex, SOTEC Afina Eye and Visionite VCS-UC300 and VCS-UM100.
pwc: Logitech QuickCam 4000 Pro USB webcam detected.
pwc: Registered as video0.
input: PWC snapshot button as /class/input/input0
usbcore: registered new interface driver Philips webcam


Cool, pwc: Registered as video0. So now we have a device :-)

Let's test it:

vidcat -p y -s 640x480 -d /dev/video0 > /share/HDA_DATA/Public/blaat.jpg


Be sure to check it, so that writes somewhere to your harddrive. I needed to use -p y, it gave me errors without it. Maybe your cam works better without it.

 

Got your jpeg image? Yipee. Now for some real security cam stuff: Motion.

edit the file /opt/etc/motion.conf

nano /opt/etc/motion.conf

Search for videodevice, make sure it point to where the usb webcam driver is loaded, mine is loaded into /dev/video0

videodevice /dev/video0

Also search for target_dir so it can actually write some files.

target_dir /share/HDA_DATA/Public/cam

I also set some other stuff so it would create a different folder each month and within each month a different folder for every day. And functions as ipcam so i can watch it from my browser op port 8081

you can grab it here: http://www.jantino.nl/blog_files/qnap_webcam/motion.conf

wget http://www.jantino.nl/blog_files/qnap_webcam/motion.conf
cp ./motion.conf /opt/etc/

 

After this, start motion:

/opt/etc/init.d/S99motion start

 

Open your browser, goto http://your_nas_ip:8081 or go to your "cam" in your Public folder and see it fill up with moment avi files.

Have fun! if you have questions, or suggestions, or just happy, please don't hesitate and fill in the form below.
