Instant Replay - Vivotek NR9581 User Manual

Instant Replay

If a camera is currently recording to the VAST server, then a Replay button will be
available at the lower left corner of its view cell. This allows you to immediately retrieve the video
recording in the past few seconds or minutes.
The Instant Replay function enables you to quickly retrieve videos of what has just happened (20
seconds to 15 minutes ago), without the need to open the Playback utility for the past videos.
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
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.
The Playback option allows you to directly open the Playback utility. A
maximized single view window will open. In this single view, previous
recording will be played, but, unlike the smaller Instant playback pane, the
playback will continue until manually stopped.
This playback mode is not memorized as the norm the next time you use
the Instant Replay function.
The queue length configuration stays with the view cell, and it will not go unless you remove
and insert the camera again.
