Low Frames per Second (FPS) + 16-camera montage pic

Post by **kylejohnson** » Fri May 30, 2008 8:23 pm

Hey everyone,

Our new ZM server is running pretty nicely with 16 PoE IP cameras (Vivotek IP7131), except with only one problem - zoneminder will not record or stream above ~4 FPS. Using the camera's built-in viewer, I can watch in nearly realtime.
Nothing is showing up in the logs (shared memory, etc), and this problem occures using only 1 camera, or all 16.

We're running Fedora 8 with ZoneMinder 1.23.2 with kernel version Linux 2.6.24.5-85.fc8 #1 SMP Sat Apr 19 11:18:09 EDT 2008

And now for the screenshot which I'm really proud of:

Can you guess where I am?

Any help is appreciated.

Thanks!

Wow! That is an impressive montage view.

I don't have experience with using Zoneminder with IP cameras but I heard they take a lot of CPU and that in turn gives you low frame rates. What frame rate do you get if you only have 1 monitor running?

Which hardware do you use for the zoneminder server?

I'm planning to replace our old dallmeier with 18 analog cams and add 4 wlan cams.
