Distributed Video Data Management System with Search Interface based on Virtual Wall

Abstract

Monitoring cameras with the capability of connecting to the Internet are increasing. This paper proposes a system which manages the distributed video data efficiently and has an interface which can be operated easily. For managing video data, the raw video data is stored in a local PC which directly connects to the camera and only the recording information is managed in the server by using a spatio-temporal indexing algorithm. The data communication is conducted through HTTP and the search input and output is realized in Web browser. For the search interface, we propose an input method of search key which does not insist users to care the locations of cameras by introducing the idea of virtual wall. We also provide a search result interface which allows users to narrow down the video data in the search result.
