Timeline
The timeline is a graphical representation of the active camera’s
activity over the last 24–48 hours. While the unit holds recorded
videos beyond the 48-hour limit, the timeline graph only shows
recordings from the last two days.
When opened within the web interface, the timeline shows 12 hours
centered on the time of the last refresh of the live view (this defaults
to the time when you logged in). Note that the live view refreshes
whenever you change camera views or return to the live page from
the configuration or log page.
When first opened in the local interface, the default display runs
from 12:00 a.m. on the left side to 11:59 p.m. on the right, covering
a 24-hour period of the current day, according to the system time
setting.
The timeline shows the activity of the active camera (the camera
with the white frame around its channel view). Within the timeline,
a blue bar shows when the active camera was recording normally,
either because it was scheduled for continuous recording or because
an operator recorded manually. The green lines indicate when an
otherwise inactive camera was recording an event, either due to
motion detection or an alarm being triggered.
The yellow bar with the time and date stamp shows what position
in the camera’s timeline of activity is being shown. This displays
the current system time if you are watching a live view, or the
time stamp of the recording if you are watching a playback of a
previously recorded event.
If the bar moves off the right end of the timeline, the timeline
automatically refreshes with the yellow bar at the center (web) or at
the left edge of the screen (local).
Click anywhere on the timeline to begin playback at that position.
Changing the Span
The web interface timeline has six zoom levels, ranging from a half
hour (measured end to end) to 24 hours.
