Autozoom helps to monitor moving objects by automatically adjusting the level of digital zoom. Autozoom shows close-in video for parts of the frame that contain a moving object or objects and follows them as they move, just as a movie camera does when taking a close-up shot. The level of zoom is automatically adjusted to catch all moving objects in the frame.

This function works with ordinary fixed cameras and fisheye cameras; in the latter case, autozoom acts as a virtual PTZ camera following the moving object.
