Good looking channel- has anyone found a working JPG stream from FosCam? I can get it on my browser at http://cameraip/snapshot.cgi -- but this doesn't seem to work with the Webcam-One app written by YungBlood.

Try http://<IP address>/cgi-bin/video.jpg I have a different model and it worked for me.

This just worked for me on Roku's Webcam One Channel using the Foscam FI8918W model.
Device Firmware Version 11.22.2.38
Device Embeded Web UI Version 2.4.18.17

Waiting for WebCam-Multi. 😄

Webcam One works great.
Anyone know if WebCam-Multi Info or a similar channel exists?

The website DNS is not registered anymore, but internet archive has the last change to the website Aug 12,2012. Anyone know if source code is available for WebCam-One / Multi ?

Images on Website are constantly updated by DVR (i.e. GeoVision) using FTP to a folder under IIS. Therefore every .1 sec a new image is written.
When I reload the roImageCanvas I don't get the updated JPG Images.
Any help would be nice!
Thanks

tag a random string to the end of the url each time you load the image otherwise it will be cached, for example:

 {
            url:"http://192.168.1.12:82/SnapShot/cam1.jpg"+"?random="+rnd(10000).tostr()
            TargetRect:{x:0,y:20,w:640,h:340}      '0,0 ~ 640,360 upper left
       CompositionMode:"Source"
        }
         

[wildcatfan1964]

Thank you!

I would have never thought of that.

Is there a way to clear the cache?

This is supposed to do it, there were some reports that it doesn't work.
