20+ Frames Per Second (fps) Issue

Hi all,

I have system with specs
* Core i5 Processor
* 4GB RAM
* 1TB Hard Disk

I have installed and configured zoneminer with the commands

1. sudo apt-get install zoneminder apache2 php5-mysql libapache2-mod-php5 mysql-server
2. sudo ln -s /etc/zm/apache.conf /etc/apache2/conf.d/zoneminder.conf
3. Installed library, libjpeg-turbo_1.0.1_i386.deb
4. sudo rm -rf /usr/lib/libjpeg.so.62
5. sudo ln -s /opt/libjpeg-turbo/lib/libjpeg.so.62.0.0 /usr/lib/libjpeg.so.62
6. sudo apache2ctl restart
7. sudo zmpkg.pl restart

After these configurations and installation, i go to zoneminder's console, i add the monitor with source type "Remote" and Max Fps "25" with resolution 320x240.

I am getting 25 fps with 4 monitors but these frames go down when i add more monitors. These go down to 7,8,9 fps.

I want to achieve 20+ fps. What can be the issue? Are there any configurations that need to be changed?

Thank You.

Regards

That might be the problem.

In general do not add a maxfps value of any kind to network cameras unless you are doing single image captures, even if it's a value above what you expect to reach. It can do nasty things to the timings. If you do want to limit the capture rate you will have to do that at the camera end by config or by capture url.

I'm not sure that is your issue here though.

I have tried that too by not specifying max fps but that also didnt work. When i enter ip in browser that works fine and give me the real time video. what is the issue with the zoneminder?
Is this a zoneminder configuration or shared memory issue or any camera configuration issue? I have assigned shared memory of (1024x1024x1024)=1GB.

Any suggestions??
