    PTZ for fixed cameras: Smart Motion Zoom allows flexible zooming in automated video surveillance

    A known issue in video security in practice: fixed cameras with a fixed or variable focal length frequently do not zoom in on the face, rather on the body or feet. The reason for this is that the person in the area under surveillance moves or the head is not in centre frame, but a conventional zoom lens always focuses on the centre of the image. With increasing zoom factor, i.e. increasing magnification, more and more picture elements are moved to the edge of the image or disappear completely from the image area. This has the effect that what matters is frequently not seen.

    Not so with cameras with the innovative Smart Motion Zoom that allows fixed cameras to execute a visual pan to capture objects or persons in any position of the image area and enlarge what is really relevant.

    This is achieved by enabling motion detection for a freely selectable image area. When the camera detects movement in this zone it automatically zooms in on an also freely definable image area. The sensitivity of motion detection, as well as the duration of the zoom, are variable and can be defined in the camera menu.

    Fixed cameras with Smart Motion Zoom are ideal, for instance, for video security installations in entrances and at cash registers, in corridors and stairwells, or at ATMs. A whole range of camera models in the eneo Candid and Callisto series feature this innovative zoom function that turns a fixed camera into a PTZ model.
