The invention relates to an image detection anti-theft alarm. The image detection anti-theft alarm mainly comprises a camera, a central processing module, a buzzer, a red light, a green light and a power source adapter; the camera, the buzzer, the red light, the green light and the power source adapter are all connected with the central processing module; and the central processing module is provided with a central processor and an operation panel; and the operation panel is provided with a manual detection key, a reset key and a switching key. The image detection anti-theft alarm has a very low false alarm rate and can accurately identify the complicated conditions of various kinds of non-manmade interference. According to the image detection anti-theft alarm, manmade movement signs are identified based on images, so that the image detection anti-theft alarm has characteristics compared with a traditional anti-theft alarm; the camera is adopted as a signal acquisition tool, since the camera is a non-contact tool, the camera is neither affected by environmental temperature nor effected by space, and has low requirements for an installation environment; and thus, the image detection anti-theft alarm of the present invention has the advantages of high accuracy, simple operation, high safety, high reliability and convenience in popularization, and can be widely applied to places such as factories, large-scale shopping malls, residential buildings, warehouses and parking lots.
