(11) The free split-screen and combined-screen server pulls the monitoring video stream to multiple monitoring devices through the monitoring information of the target monitoring device.

(12) After the free split-screen and combined-screen server receives multiple monitoring video streams, it encodes the multiple video streams according to the video position information in the free split-screen layout template, and obtains one video monitoring after encoding.

(13) The free split-screen and combined-screen server sends the encoded video surveillance to the visual network video surveillance platform through the non-primary virtual terminal number allocated by the monitoring access server.
