Step 57; After video surveillance management module (102) receives that forwarding is successfully instructed, set up the information of the video source after switching, and just instruct in program request to video monitoring switching client (2) transmission; If this conversion link exists; Then need be through network communication module notice video monitoring center (3) the terminal equipment information of reaching the standard grade, if this conversion link does not exist, then notify video monitoring center (3) the terminal equipment information of reaching the standard grade through network communication module;
Step 58, video monitoring switches client (2) will give tacit consent to the video source that video source resets to needs switching;
Step 59, video surveillance management module (102) is carried out preset point control to video surveillance applications module (101) request to terminal equipment;
Step 510 after video surveillance applications module (101) is received the instruction of terminal equipment preset point control request, forwards the camera lens of video source to corresponding preset point position.
