Mixed multi-scene, multi-application snapshots.

In related technologies, the transmission process of captured pictures is shown in Figure 1. IPC continuously collects images of the monitoring scene when it is working, and analyzes the currently collected images through computer vision technology. When it meets the preset capture conditions, it generates Capture pictures, and encode the captured images into video frames at the same time, and each video frame forms a video stream; then send the captured pictures and the video stream composed of each video frame to the storage device in the video cloud storage for storage.
