Just wanted to add my vote for a motion detection zones feature.
I have my camera located at the front entrance of my home. It helps protect against burglers, and allow me to see who is at the door when I am home. The problem is, on windy days the swaying shrubs set off the motion detection frequently. It would be useful to block them out of the motion detection area. Currently my only options on windy days, is turning off iCamSource, or letting my drive fill with false alarm images.
