VIVOTEK
Prerequisites for Instant Replay:
1.The function is enabled by default, only available on a LiveClient installed on a PC.
2.There must be recorded videos of the immediate past. If the video streams from a camera were not recorded, you can not retrieve videos using the Instant Replay function.
NOTE:
1.When using the Instant Replay function and you change the stream number on a video cell, the Instant Replay will be interrupted.
2.The Instant Replay will also be interrupted when the time comes for a rotation of Live View pages. For example, if you have multiple Live View pages and you set up a rotation of these pages by every 10 seconds, page swap (rotation) still has a higher priority even if you are viewing the Instant Replay.
How to Use:
1.On a selected view cell, mouse over to the lower left corner. A Replay icon 
will appear.
2.Click on it to display the Replay control bar. Click on the play button.
3.The default queue length is 30 seconds. You can click on the number on the right to change
the queue length.
4.To stop the Replay and return to the Live View, click on the Return to Live button. 
5.On a Replay view cell, you can apply the same Snapshot, Print, Single view and Full screen control as those on a normal view cell. You can also
Click and drag the playhead to skip or move to a different point in time on the playback. 
An active Replay view cell is indicated by the Replay text indicator and the time of occurrence of the current playback.
