Didn't know whether to put this in chit chat or here.

Nice little story about how an IT system linked to an underwater camera was able to pick up a little girl in distress and alert human lifeguards to it. Probably saved the little girl.

One of the safety system's four underwater cameras showed her sinking without any sign of a struggle into the 12ft 6in deep end.
Once she had lain motionless on the pool floor for three seconds, the computer sounded an alarm which also pinpointed which part of the pool the girl was in to the five lifeguards on duty.
