for these days i've been working on some kind of thing which can work just like the zoneminder--with a monitor on guide , it can judge whether somebody or something gets into the zone you choose and the camera will then take a photo and send to its host far away

anybody knows how the zoneminder realizes such a function by programming in C++ language? just a simple explanation will be great --

Unfortunately a simple explanation is not very easy to come up with as it's not a simple process. As James suggests looking at the code and/or ready the documentation is probably the best way to get started.

Googling for 'motion detection algorithms' comes up with a number of promising looking pages that might help.
