Diagonal potential-based camera monitoring method and camera monitoring system

The invention relates to the field of security and protection, and particularly relates to a diagonal potential-based camera monitoring method. The method is as follows: a first camera and a second camera are arranged diagonally; the first camera acquires a first video stream of a target scene; the second camera acquires a second video stream of the target scene; the first camera and the second camera send the first video stream and the second video stream to a background server; the background server acquires the face information of the front face of a target human body according to the firstvideo stream and the second video stream; the background server judges whether the target human body appears in the first video stream and the second video stream at the same time or not according toa face recognition algorithm; when the target human body does not appear in the first video stream and the second video stream at the same time, the background server controls the first camera and the second camera to continu
