I am wondering if there is any C++ library for reading multiple IP cameras and do the simplest motion detection. I of course know OpenCV can do this but it is kind of heavy when it comes to multiple cameras. My target is 20 IP cameras. I have seen commercial applications doing this task, so I know this is somehow possible for sure. Below are some commercial applications which can do motion detection on multiple IP cams.

  1. http://www.deskshare.com/video-surveillance-software.aspx
  2. http://sourceforge.net/projects/surveillance/
  3. http://www.nchsoftware.com/surveillance/
  4. http://download.cnet.com/Camera-Viewer-Pro/3000-2348_4-75123285.html

I am seeking for a C++ library because I need to run trigger some OpenCV code on motion detection.

Any ideas please?

Basically they all programmed it from scratch to get efficiency! That your only goal here :) You should split up your algorithm into basic blocks and find the most efficient implementation for each part. Things you will have to look into are:

 1. Efficient background subtraction
 2. Efficiently performing AND operations
 3. Make a multithreaded interface with a thread for each CAM and a main thread which combines all previous data.

This will be the only way to achieve a robust system with that many camera's. Getting your camera's synchronized however will be another great challenge but it gets out of scope of this forum.

@StevenPuttemans: Thanks for the reply. You mean use OpenCV, but use it efficiently with best ways and our own tricks?

@StevenPuttemans: oh, and another thing, SimpleCV can do this, but it is in Python :(

Yes or try to manually implement techniques that show better results than OpenCV. For example OpenSURF gets way better results than the straightforward OpenCV SURF implementation and it is faster in processing.
