UNDERSTANDING INSTANT PLAYBACK
The DX8000’s ability to perform instant playback of video is limited by a one-minute delay interval. The DX8000 has a built-in latency of
approximately one minute between the time that video is captured and when it is written to the hard disk. This delay exists to ensure that video
is accurately stored and that the DVR’s database is updated correctly.
The delay interval is not affected if the DX8000 is in the alarm or motion record mode. In this case, the pre-alarm or pre-motion time period does
not become a factor in determining the delay interval.
To initiate an instant playback:
The user has the ability to view video that is just recorded. This video image resides in memory and has not yet been stored on the hard drive.
The color of the timeline will be green. This is because the system cannot tell what the data characteristic is while the data resides in memory
For example, if this data is recorded from a camera configured to monitor motion, and there is no motion activity, the data will not be stored on
the hard disk drive.
On the playback control, click Instant Playback. The timeline is zoomed to the last two to three minutes of data.
