Abstract: A tracking method for a video surveillance system includes: obtaining identification information for a first target object uploaded by a positioning system; obtaining time information and location information for the positioning system at the time the positioning system uploads the identification information; storing the identification information, the location information, and the time information in a preset database to obtain a storage result; and generating tracking information for the first target object according to the storage result.

Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device associated with a social networking application. While running a social networking application, the first computing device detects a near-field wireless communication signal broadcasted by a second computing device associated with a service provider account registered with the social networking application.

Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device. While running a social networking application, the first computing device listens to a near-field wireless communication signal broadcasted by a second computing device. After detecting the near-field wireless communication signal broadcasted by the second computing device, first computing device processes the near-field wireless communication signal to obtain identification information associated with the second computing device. The first computing device sends the identification information associated with the second computing device to a remote server supporting the social networking application and obtains a preset service page corresponding to the identification information associated with the second computing device from the server, and displays the preset service page within the social networking application on the first computing device.
