Chapter 7

Playing back a recording

The recorder lets you 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, events, bookmarks, or snapshots

 Search the system log

The recorder 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 136 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 125).
