I have a system of cameras and use Security Spy
<http://www.securityspy.com/> to monitor them and to do the motion
detection. Then I have  Rev app that keeps track of the number of
files that Security Spy saves and if the number increases beyond my
set limits and within certain time frames, my app does other forms of
alert: email, SMS, phone calls etc.

To do it all in Rev, I guess you need the revVideoGrabber to keep
monitoring the camera and storing snapshots. It would have to compare
the imageData with the previous data and work out of there was enough
change to be considered as detected motion. That is the tricky bit and
it needs to be fast too.
