This works using the CrazyPilot vlc-wrapper trick here:

That will let you intercept and forward on an ffmpeg compatible h.264 stream.
Although I havn't tried this, the camera almost certainly works using NickYoung's patch for ffmpeg here:

The disadvantages of the h.264 stream include:
1/ You will notice jpegs are very obviously superiour in quality, in particular the h.264 motion compression artifacts at 1920x1080 are unacceptable to me.
2/ You have to compile Zoneminder and ffmpeg from source so no simple repo. install.
3/ decoding an h.264 1920x1080 stream takes a lot of grunt. My i7 920 couldn't decode it faster than 20fps; that took 100% of one core! This negated the one h.264 advantage of faster frame rate; I would have had to reduce the fps to 12.5fps to get it to work which is better than 7 or 8 but not worth the effort.
So if you want to stream jpegs the url is:
http://xx.xx.xx.xx/liveimg.cgi?serverpush=1&jpeg=1
Using the jpg stream you get 7fps at 1920x1080 using 'Fine' and this goes up to 12fps if you use 'Basic'. Basic looks very pixilated though. You can get upto about 30fps at 1280x720 resolution.
