Preview (Multiple Frame) Mode - Hawking Net-Vision HNC700PT User Manual

color-inverted region by dragging your mouse cursor as you hold down the left
mouse button (as shown in Figure 5-7). As you release the left button, the
color-inverted region will replace the original time range as the new period the
program displays. If you click on the left button without holding down and dragging
it, the command will be the same as clicking on the Pull Bar in the same x-axis
position. That means the Playback system will be shifted to the appointed time and
shows the video in the displaying frame. The dark regions in the histogram area
means there is no video data existed in these intervals. If you click on these regions,
a warning message will pop up.

5.6 Preview (Multiple Frame) Mode

You can enter the event Preview mode only if you have changed the playback
method selector to "Events Preview". This can help you to identify the objects that
triggered the events, not only by the time information and the alert percentage in the
histogram area but also by playing the real video preview. This allows you to easily
distinguish between different alert situations. Under the Event Preview mode, the
Pull Bar, "Transducer" button in the exporting toolbox, and the Display Adjustment
Toolbox are disabled. The two labels under the Pull Bar show both the number of
displayed events and the total event count. There are nine frames in the display area
that we call one "page". Each of the nine frames on each page displays a different
video sequence event. Each event displayed will be of at least 10 seconds in length.
You can use the "Page Up" and "Page Down" button in Page Control to browse the
events in the selected period, up to nine events per page. There is also page status
informing you the current page number and the total page count (as shown in Figure
5-8).
