Hacks for the Linksys WRT54G wireless router
Portless Networks' linux distribution for the Linksys WRT54G wireless router
wrt54g v1.1.jpg The other day I put this hacked firmware on a spare router. It was fun to look at the additional capabilities that are offered (such as SSH) but what I would really like to do is be able to modify one of these and put a very light weight streaming server on it. Unfortunately, you need a solid Linux box setup (I have to get to work on that one) to build a new firmware image.

wvc11b.jpg Oh yeah, what is MORE interesting (to me at least) is that Linksys has made available the firmware for their wireless cameras as well (also Linux based). Looking through the firmware image for the WVC11B I was able to confirm my suspicion that in fact they do not offer a true MPEG-4 solution, rather it appears as though they *may* be using an MPEG-4 codec but wrapping it in an ASF file (hence the reason you need the stoooopid active x control to view the stream).

In any case, it is one of my missions to hack a true MPEG-4 solution onto one of these. How cool would that be!

I don't have one of these, but I do know that mplayer can handle all sorts of streams. Try the following:

(By the way, liked the podcast!)

Thanks Mark.. Some interesting information at that URL. I will have to get a hold of one of these and keep digging. What I was looking at in particular was the source for the webserver that handled the requests for video. If in fact they are streaming H.263 via rtsp then it should play in QuickTime, MPlayer and many other applications which is very good news.

I need a hack for the WVC11B. I need it to be able to take a picture every 20-30 sec and then FTP that to my web site. Or if I can get it to capture a picture somewhere I can figure a way to upload it. I'm using XP Pro Sp2.
Please send me any info you might have;

Hi guys.

Pleased to meet you.

Finally i find people playing around with the same gadgets I am.

I made MediaPlayer Classic to play the stream from the camera using he http protocol and the /img/video.asf url,..nothing new I guess. But it stops, buffers and strats again. pretty anoying. I got same performance at Winamp and WMP 10.

It would be great If anyone has hacked this so I can simply watch my camera from Media Player.

this is awesome. There is a lot of misinformation about what this camera wONT do. It will stream mms and rstp to media player, which can be embedded in any web page.
i hope to see someone get creative with the source available on the linksys site. in the meantime the visiongs software is a good plug and play alternative.

Posted by: dkraft at March 6, 2005 06:53 PM

I highly recommend the VisionGS software from http://www.visiongs.de/. It pulls captures or streaming video directly from the camera and uploads or relays to any site you wish.

This non-techie with linksys 80211.b cam hopes someone will tell me how to futher (went to 1 already) reduce brightness so I can cam backyard. Will it take a hack, filter...what? And, can a more sophisticated digital camera be substituted or replace the cheap fixed focus one from Linksys. Thanks.

Solution to the Linksys web cam brightness control in which even turning down the brightness to 1 got whiteout when shooting a sun-lit backyard. I took a pair of kids 3-D glasses with the grey polaroid plastic lenses and tore them apart so by placing one lense directly in front of the other so I could create a variable density filter by rotating one of the lenses. Reset the camera brightness to the default 32...rotated makeshift filter until I got the perfect pic and taped homemade lens filter to camera lens. Someone should manufacture these on the cheap. I plan to use a bottle cap to make my own snap-on filter and put a tab on each piece of polaroid plastic so I can adjust density at will. If anyone wants to see the effect I got let me know at lyeager@hotmail.com and I will give you the cam URL.

I want to connect a WVC54G to my Airport base station and then use a PC from outside to view images of family at home. can this setup work? How do I best figure out the correct IP address as the Airport base station is supposed to assign IP addresses dynamically. The base station is connected to a broadband ADSL modem. I am able to configure the WVC54G to connect to the Airport with the proper WEP amd MAC address settings. Thanks!

I have a westell router from a previous IP. I want to use it with my new IP. I dont have the user name or password anymore. Is it possible to use it, or reconfigure it??

Hey guys,
i came across your thread here while browsing for other wireless router tools, and i noticed youre all looking for a camera with a built in FTP. I use this, WebCam NX Ultra USB which has auto face tracking, an 78*Degree angle view, and ofcourse the built-in FTP program. I've been using it for over a year. Price is great! 70$ Bones these days is easy. Has built-in webpages if you like to really make it easy on ya. Just have a ftp site, set time intervals and sit back! I use it to watch downtown seattle while iam at work. Check out CompUSA's description of it here http://www.compusa.com/products/product_info.asp?product_code=312827&pfp=SEARCH

peace guys..

Try the below to post externally. I used this to add to my website. Really basic object. Replace with the IP assigned to your router by your internet provider. Change the to the port you opened in your router that forwards to your web cam.

:/img/video.asf" />

Does anyone know if the LinkSys WVC54G IP camera stores the currently grabbed still image somewhere? Pointing to the /img/video.asf stream is great but it would be handy to be able to grab the current still frame too.
Thanks.

I found that if you use MPlayer on any platform OS X/Windows/Linux/BSD will work just fine with the wvc11b.

Using the commandline (may differ a bit depending on playform):
mplayer -dumpstream -dumpvideo /my/files/dump.asf 192.168.1.115/img/video.asf

This will save the stream to individual asf files, playable in pretty much any media player. I use a bash script through cron to create/kill these processes for 9 cameras at once. Works pretty good.

My wish list would include a firmware update to display the strength of the wireless signal in the web interface.

Happy to help if anyone needs more info.

I have tried the Webcam Transmitter from Cambrosia and it streams higher qulity video than anybody out there today. This is the best Webcam software I'e seen.

I'm trying to grab the video feed from my linksys WVC54GC camera. Tried the http://xx.x.xxx.xxx:1024/img/video.asf it launched the windows media player, but kept trying to buffer with no video shown. Any ideas?

Posted by: Bill at February 2, 2006 01:08 PM

I have a wireless linksys router and need more antenna gain as I have an older home and have poor signal strength. Is there a hack to replace the firmware???

Thanks,

Keith
