Operation of video signal processing aimed to produce an output indicating the pixels or groups of pixels which belong to moving objects as opposed to static portions of the picture. Synonyms: Motion Recognition
A feature used in multiplexers that uses video motion detection techniques to improve the camera update times. It can also give a relay closure.
Detection of an intruder by making use of the change in location or orientation in a protected area as the intruder moves around. In video motion detection, this means changes in key parameters of a viewed scene from a recorded reference image of that scene. See Motion Detection Alarm, Motion Detector.
Motion Detection refers to a grid established within the camera view. When a moving object enters into the grid an alarm is triggered sending notification to the user.
Recording method for digital surveillance systems. When someone walks in front of a camera, the pixels change and the DVR defines this as motion. The surveillance system will then record these images to the hard disk. This is a popular recording setup as every event recorded is actually motion driven as opposed to a static image if the system was set to record 'round-the-clock'.
Network Cameras equipped with motion detection can identify motion or change in the live video. The sensitivity can be set by the user in the configuration settings of the camera. Some network cameras can also email and FTP images or video showing the motion detected.
Motion Detection is a feature that alerts you when motion is detected in your camera's field-of-view, enabling video recording to start automatically. Once motion is caught by your WebCam, you can choose to be alerted via email or an audio-alarm, or even have the first frame of the video uploaded to a web-site.
Refers to the feature in some VCRs and DVRs to record only if something in the image moves or changes. This feature saves a lot of space on the tape or hard drive.
Motion detection is the sensing (usually by electronic devices) of physical movement in a given area. The principal methods by which motion can be identified are infra-red detection and acoustical detection. Motion detection sensors are available which can easily detect movement and produce an alarm or switch on an image recording device.
