Abstract: A motion detection device is matched with a passive detector utilized to detect an object and to accordingly generate a triggering signal. The motion detection device includes an image capturing unit and an operating processor. The operating processor is electrically connected with the image capturing unit, the operating processor is adapted to switch the image capturing unit from a sleep mode to a wakeup mode for motion detection while being triggered by the triggering signal, and further to optionally actuate an external host in accordance with an analysis result of the motion detection. A motion detection method applied to the motion detection device includes receiving the triggering signal, switching the image capturing unit to the wakeup mode for capturing the first monitoring image, analyzing the first monitoring image to determine existence of the object, and actuating the external host in accordance with an analysis result of the first monitoring image.
