Playback Video
The DX4500/DX4600 supports two playback modes: playback and instant playback. The playback mode is accessed from the search window and is used by the search feature to display video resulting from a search operation. Playback video is displayed in PIP presentation in the application window. For information about the instant playback mode, refer to Instant Playback on page 97.
PLAYBACK VIEW AND CONTROLS
The playback mode has the following conditions:
•Playback: By default, playback video is displayed in PIP in the center of the application window. One, four, nine, or sixteen channels can be simultaneously viewed in a custom display. One playback channel is displayed in a single pane, two to four playback channels are displayed in four views, five to nine playback channels are displayed in nine views, and ten or more channels are displayed in sixteen panes across the entire window. When sixteen channels are displayed simultaneously, the playback window cannot be moved and live video cannot be viewed. However, the DVR continues to record video.
•Viewing video: The Client application plays back most, but not all, of the video frames received from the DVR server. Conversely, the DVR server plays back video in it’s entirety. Therefore, video played back and viewed on the server, when played back and viewed on the Client, does not include all video frames.
•Selecting playback panes: Multiple panes can be selected one at a time in the playback mode. A red border highlights the selected pane.
•Playback controls: All playback channels are controlled simultaneously. An operation performed on one channel is automatically performed on all playback channels.
•Supported search modes: With exception to the bookmark search feature, the playback mode is available for all other search modes. The bookmark button is unavailable if an external backup device is selected.
•DVR operation: Recorded video can be viewed in the playback mode while simultaneously viewing and recording live video.
•Timing: Playback can be configured to begin two minutes prior to the start of an event.
In summary, to playback video:
1.Open the search window.
2.Search a channel for data.
3.From the search window, start playback. The playback video is displayed in PIP presentation.
