Abstract
An apparatus (10) includes a display (14), and includes a focal plane array (12) which can detect infrared radiation from a scene. The focal plane array outputs successive images of the scene, which are comparatively analyzed to identify movement of persons or objects within the scene. Pixels corresponding to detected movement are highlighted in an image presented on the display. A device (117) can be provided to generate an audible sound in response to detection of movement.
