Video surveillance to get smarter

Something to watch out for. Big Brother is getting closer and closer.

From CNN:

In some cities in Europe and the United States, a person can be videotaped by surveillance cameras hundreds of times a day, and it's safe to say that most of the time no one is actually watching.

But the advent of "intelligent video" -- software that raises the alarm if something on camera appears amiss -- means Big Brother will soon be able to keep a more constant watch, a prospect that is sure to heighten privacy concerns.

Combining motion detection technology with the learning capabilities of video game software, these new systems can detect people loitering, walking in circles or leaving a package.

New microphone technology can isolate the sound of a gunshot and direct the attached camera to swivel and zoom in on the source. Sensitivity may reach the point where microphones could pick out the word "explosives" spoken in a crowd.
