One problem known from video security in practice: cameras with a fixed or variable focal length frequently do not zoom in on the face, rather the feet, because the person moves or the head is not in centre frame - assuming the zoom did not actually go fully past the crucial event. Of course, this problem can be avoided by installing a PTZ model or multiple fixed cameras, or also by opting for one of the latest Candid or Callisto models from eneo with their Pointing Zoom and Smart Motion Zoom features allowing flexible definition of the zoom area. They support users in retrieving the exact image area relevant for identification of persons or assessment of a situation. The key factor is that this image area can be anywhere in the camera's field of view.
Both features are based on the same principle with the difference being that Pointing Zoom is enabled manually when viewing live, whilst Smart Motion Zoom activates in automated video surveillance as soon as the camera detects motion in a specific and also freely defined image area. The sensitivity of the motion detection and display duration of the zoomed image is variable and can be specified individually.
