Bandwidth limit, It seems

This might be better posted on the ubuntu forums, but It does deal with Zoneminder and camera's.

I'm almost noticing what would seem to be a bandwidth limit for camera's using Zoneminder.

Im noticing what seems to be a limit as to how fast zoneminder is able to access the camera's.. Seems like it cant go through the frames fast enough.

All the camera's (4) are at 100 mbits. I seem to only be able to get about 4-6 FPR out of them all. I want to try and get 15. I have 4 camera's and my CPU load is at about .4 - .6. 8 gigs of ram...

Seems like it should be able to get to or at least close to 15 FPS, But its not.

I set 3 of the camera's to 'None' and I confirm my bandwidth goes down, it would seem that the system is only allowing so much bandwidth per stream?

Anyone out there ever hear of this?

The issue is on your cameras, what model are you using?

I have 25 ip cameras on one box with 100mbit and I don't have any problem.

I have 4 camera's.

1 axis 207
2 axis 209
1 axis 211

Whats weird is that cheapest camera I actually get the best FPS of about 9.

If I browse to the camera directly I get 25-30 fps.

Hmm I found something new. I was messing around with the configuration on the camera and I noticed at times it would jump to 10 fps (Which it what I have it set to now).

I noticed whenever I open Live' View on the camera itself and have essencially have both live views open zoneminder goes to 10 fps, otherwise it sits at about 7 fps normally.

Now I know this is related to the camera, But im hoping maybe someone out there has run into this? Ill try axis's site also.

Okey, I found the solution..... Sorta.

I was using this string for my camera's

/axis-cgi/jpg/video.cgi?resolution=640x480&fps=15

And I had to change it to

/axis-cgi/mjpg/video.cgi?fps=25

Key difference was the "mjpg" instead of "jpg" and removing the "640x480" all together.

Im running at 25 fps on all 4 camera's with no issues (Other then disk space).

Thanks for anyone that gave help or considered giving help.
