Abstract:
1. A computing system, comprising: a storage system; at least one processor; and one or more programs being stored in the storage system and executable by the at least one processor, the one or more programs comprising: an obtaining module operable to read a current real-time image of an area captured by a camera; a control module operable to control a motion detection unit of the computing system to determine a number of varied pixels in the current real-time image compared with a previous image of the area, and determine a ratio of pixels of the number of the varied pixels to a total number of pixels in the current real-time image; a setting module operable to put the camera in an alert status if the ratio is greater than a predefined value; a calculation module operable to increment an abnormal image count by one; the obtaining module further operable to read a next image captured by the camera if the abnormal image count is not greater than a maximum abnormal number; and the control module further operable to start an alarm device connected to the computing system if the abnormal image count is greater than the maximum abnormal number.
