Playing back a recording
The NVR lets you to quickly locate and play back recorded video. There are four
ways to play back video:
Instant playback of the most recently recorded video
All-day playback of the day’s recorded video
Search the video archives by specific time, date, bookmark, snapshot or
event
Search the system log
The NVR continues to record the live view from a camera while simultaneously
playing back video on that camera display. You must have the access privilege to
play back recordings (see “Customizing a user’s access privileges” on page 128
for more information).
Cameras in multiview mode play back simultaneously. This means, for example,
that it is easy to follow the path of an intruder who has passed in front of several
cameras.
Overview of the playback window
It is easy to manage playback from the playback window.
The playback video can be set up to display a time/date stamp for evidentiary
purposes (see “Configuring the camera OSD settings” on page 117).
