The cameras can be divided into network digital cameras and analog cameras and can be used for collecting front-end video image signals. The complete video monitoring system is mainly composed of camera shooting, transmission, control, display and record registration 5. The video camera transmits video images to the control host through a network cable or a coaxial video cable, the control host distributes video signals to each monitor and video equipment, and simultaneously, voice signals needing to be transmitted can be synchronously recorded into the video camera. Through the control host, an operator can send out an instruction to control the up-down, left-right and left-right actions of the holder and perform focusing and zooming operations on the lens, and the switching among multiple paths of cameras can be realized through a video matrix. By using a special video recording processing mode, the operations of recording, replaying, calling, storing and the like can be carried out on the images.
In the whole video monitoring system, at present, cameras are also adopted for fixed-point laying, that is, only one camera is installed at a place to be monitored, and for the same large area, if monitoring is to be realized, the monitoring can be realized only by installing more monitoring cameras, and the defects of the method mainly lie in the following two points:
(1) the cost increase of the monitoring equipment is increased by a multi-machine installation mode;
(2) because the picture shot by each camera only comprises one local picture, when the monitoring target moves in the area, the dynamic state of the monitoring target can be observed only from each lens, and the monitoring target cannot be observed from the overall or global view angle.

And then the selection frame is utilized to output the selection frame in the global frame, namely the selection frame is utilized to simulate a single camera in the traditional mode, namely, several selection frames are used for having several cameras, so that the pictures of different monitoring points are output, thus obtaining a global frame and a plurality of local monitoring frames, when a monitoring target appears in a monitoring area, the global-to-local dynamic visualization of the target can be realized, the local-to-global dynamic visualization can also be realized, and the monitoring reliability is enhanced.
Further, the global picture is an 8K video picture, and the size of the selection frame can be adjusted through an AI algorithm, so that the size of the selection frame gradually increases or decreases;
when the frame is changed from small to global frame size, the visualization from local to global is realized;
when the frame of the selected picture is reduced from the size of the global picture, the visualization from the global picture to the local picture is realized.
Further, the image acquisition module comprises at least one or more 8K cameras, and when the monitoring area is large enough, the 8K cameras can be used for covering.
Further, the partial pictures output by the frame selection are different from each other in overlapping, or only partially overlapped.
Furthermore, the number of the selected frames is 16 at most, and the length-width ratio of the selected frames is 4:3 or 16: 9.
Furthermore, the local picture output by the frame selection frame is a 4K picture or an HD picture.
Furthermore, the selection frame adopts manual configuration or AI identification technology to perform positioning selection and output a local picture.
Furthermore, the 8K camera is fixedly installed by adopting a rotatable base, so that the horizontal visual angle and the pitching visual angle of the overall picture can be adjusted.
