Multimedia systems for industrial surveillance

The need for multimedia systems for industrial surveillance is rising in various industrial fields, such as plant monitoring, control systems, and security systems. In this paper, we concentrate on video information, which it is thought will be effective in surveillance support. We describe the development of our 'media controller' as a platform for this multimedia system. A media controller individually records large capacity video data continuously with a camera, and provides video data according to the scene, time and QoS demanded by the surveillance center in real time. With the media controller, we can easily give facility surveillance applications new advanced functions. For example, the media controller can be connected to the plant facility alarms and provide video data before and after an alarm as soon as the alarm is activated. Moreover is does not fail to capture data even if many alarms occur in a short time. We propose a mechanism to manage video data which consists of a continuous recording, event recordings, event recordings which are connected to the alarm events, and along duration timelapse recording.
