The invention relates to a device and a method for the intelligent linkage of a multi-video recording device based on cloud computing and mass video searching. The device comprises a video recording device, a moving target dividing and tracking device, an OCR device, a moving target feature extraction device, a moving target storage device, a searching device and a visual user operation interface. A moving target is divided and tracked by recording the video information and the geographic information of the moving target, then the features of the moving target are classified and extracted, the information of the features of the moving target is stored, and abnormal event information is displayed to a user by user searching. A human-in-circulation strategy is adopted, the problem of accurate tracking of a cross-video recording device is solved by using a mode of assisting an operator by a computer, and the problems of low human information processing speed, weak memory capacity and high labor cost are also solved.
