In one embodiment, as shown in fig. 2, a video surveillance data obtaining method is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
s200: and receiving a video monitoring data acquisition request.
The terminal sends a video monitoring data acquisition request to the server, and the server receives the video monitoring data acquisition request. Specifically, the terminal may include a smartphone, a tablet, a terminal computer, and the like. The video monitoring data acquisition request may carry a request to view the location area identifier, for example, if the user needs to view the video monitoring of the campus area 1, the user operates on the terminal to generate the video monitoring data acquisition request carrying the campus area 1 identifier, and sends the video monitoring data acquisition request to the server.
S400: and analyzing the source and the network environment of the video monitoring data acquisition request, and identifying whether the video monitoring data acquisition request is a local area network request or an internet request.
