I looked at the stream requested by the streaming applet, it seems the video URL is the following:
rtsp://188.8.131.52:554/axis-media/media.amp?videocodec=h264&camera=1&streamprofile=Balanced. The last parameter is customizable with the other selectable options like 'Quality', 'Bandwidth', etc. You then need a program that can capture RTSP video streams, google should help there. You probably need to try a few until one works.
I just tried VLC, it can view the stream just fine, but when you try to save it, it just saves garbage data.
Edit: Here is how I found the URL. The hardest part was actually getting the stream to work in any browser the regular way. It finally worked on windows with the quicktime plugin installed for firefox. Then I used Wireshark to sniff all traffic from my PC to the website in question. You now have all information you need about the stream. You just have to find it.
First thing I did was filter all recorded packages for the IP adress given:
ip.addr == 184.108.40.206.
The next thing I noticed was that the communication changes from http to rtsp as soon as the quicktime plugin loads. This looks like this:
So the information had to be shortly before or after this point (Because I found nothing before that, and only raw video data was following). Turns out there is a RTSP packet
Reply: RTSP/1.0 200 OK, with session description that contains all our infos:
Et voilà! (Agreed, you probably have to know a bit about network protocols to find your way around wireshark. But it's actually not that bad.)
