The maximum capacity of a continuous backup file is 600MB. If the selected data exceeds
600MB, the file is split. If this occurs, a number is appended after file name and the same ID
is assigned to every split file. This makes it more convenient to manage data on a CD,
where the unit of partition is 600MB. A backup file has the *.rec file extension.
Every divided data file has the same ID. Although the backup file is divided into smaller
parts, they maintain a relationship to one another. This means that when one of the divided
files is played, the whole data information is indicated. These files should be stored in the
same directory. If they are stored in various directories, only the files in same directory can
be played back.
The backup data can be played back through Playback viewer. To play back a backup file:
•
Click on the “Select Camera” icon on the Playback viewer.
•
Click on the “Open Backup File..” button.
•
Browse to the backup file and click on the file name
•
Click on the “Open” button.
•
To get access enter the password given when the backup was made.
5.5 Playback Control
Playback control selects an event type to search on. To select an event:
•
Click on the All button to select all recorded images for replay.
•
Click on the MD button to playback images that are recorded with ‘motion detection’
event.
•
Click on the S1~S4 button to playback images that are recorded with sensor detected
events.
5.5.1 Play Speed:
This controls play speed (0.5x/1x/2x/4x/Max) using a drag
slider.
Note:
If the user’s Network transmission speed is slow, not all of the recorded
frames can be displayed at the selected speed. Then, the Playback Viewer
keeps up the selected speed by skipping frames.
Speed options:
•
0.5x: This plays back recorded images at half the speed of the original recorded images
(playback takes twice as long).
•
1x/2x/4x: This plays recorded images at original speed, double speed and four-times the
speed (respectively) of original recorded images.
•
Max: Every frame is played without skipping any frame at the maximum network
transmission speed.
