its late but i have the rtsp stream now:
rtsp://*ip*:8554/live00_rec
for camera1 live00_rec, 2 live01_rec and so on.
i found out the url with the onvif device manager tool.
perhaps you need to make a firmware update first.
Im searching for the exactly same thing. I tried your link Paul but I do not get a picture of a camera
I changed password and login to admin and i tried this here:
http://admin:admin@192.168.0.12:80/1.jpg
firefox just writes 404 not found, any idea?
