Such systems are used as a virtual tripwire in major airports to identify possible terrorists and illegal activity. Rather than having a person assigned to monitoring the video feed, a computer scans pixel changes looking for patterns that are indicative of possible problems. If the computer finds such a pattern, it automatically alerts security personnel - who can respond immediately or review the footage, depending on the type of alert (and local policy).
The state-of-the-art software is getting pretty sophisticated, and can detect specific behavior and objects. It's a far cry from older Video Motion Detection technology. See also Facial Recognition System.
