event log, etc. Motion detection options for different time types can
be set for each camera input using a 16 (width) by 12 (height) target
overlay. You can also enable or disable motion alarms for different
time types. However,
the recording frame rate is NOT
influenced by motion detection for the digital video recorder.
1.2.5 Video Display
The VGA monitor displays either live camera pictures or pictures
from hard disks. The display resolution is 800x600(NTSC and
PAL). As many as 16 million colors can be displayed in the
following screen formats: full screen, 4 windows, 7 windows, 9
windows, 10 windows, 13 windows, and 16 windows. All the main
displays are window based look and feel for ease of user operations.
1.2.6 Video Playback
The user can select a previously recorded hard disk to review the
recorded video. Displaying of the recorded video is composed of
decoding the JPEG or MPEG-1 encoded video automatically and
multiplexing each camera video to its designated video window.
With the coded data that was inserted into each recorded picture, the
digital video recorder can reconstruct each camera’s tag name, status,
date, and time information automatically. The image can be
displayed in any multi-window format on the VGA monitor, just like
in live video mode.
1.2.7 Non-editable Recorded Images
The retrieved images are saved as .MPG files or .MOV files, which
can be played by Media Player or QuickTime. Therefore, those files
are editable by the video editing packages, just like the recorded
images in the other digital video recorders. However, the recorded
images in the hard disks are not editable by the video editing
packages. (They even cannot be seen by those packages.) That is
to say, the recorded images are guaranteed to be the original images.
