camera number 1. Without further settings you could
already play back the event by pressing the Play button
on Playback Control Panel (shown as number 10 in figure
4-1). Click on the camera view switches the current
view mode to a multi-channel view. Use buttons on Playback
Control Panel to view the event at the way you want.

events in Video Events pane. To select a segment of
events, select the first event to be displayed, then
hold the Shift key on keyboard while selecting the last
event. Press Play button would play these events. To
select events from different dates, click the date from
the Date pane. Events of that date will be listed in
