Synology DS418 Transactions in Surveillance Station 8.1.0 and above - Page 21

Applications Transaction devices added in Surveillance Station can interact with other applications in Surveillance Station to provide more useful functions. This chapter introduces how to set up the transaction device settings in other applications. Live View Users can include transaction devices in the layout in the Live View application by editing the layout in Live View Layout Management, in order to watch live feeds of the paired camera with overlaid transaction data. You can see live view streams of the paired camera in the transaction device region. The received transaction text will be overlaid on the screen using the style that has been set up, please refer to Set up the display style. If the text exceeds the screen range, the oldest messages will be rotated out of the screen. By default, the screen will be cleared automatically if no data is received within 10 seconds. You can also temporarily hide the received text by clicking the on-screen display button below. Live View Alert Events from transaction devices, including New Transaction Received and User-Defined Events, can also trigger alert events under Alert Management in the Live View application, in order to notify you that abnormal transactions might have occurred while you are watching video streams in Live View. When alert events are detected, you can watch recorded videos in the Alert History tab in Live View > Alert Management. Events triggered by the camera, such as digital input events, motion events, and other events will usually remain triggered for a period of time. However, transaction events are triggered upon detecting certain keywords from the raw data received, and therefore will not remain triggered for a longer period of time. You will see that the duration for all transaction events are no longer than 1 second. However, when you play back the transaction events, an additional 10 second footage before the triggered event and 20 second footage after the triggered event will be played. You cannot play transaction events if there is no camera paired with the transaction device. 20 Applications
