During video playback, the selected pictures can be saved to floppy
disk, ZIP disk, CD-RW, DVD RAM etc. in .MPG format for MPEG-1
encoded video or .MOV format for JPEG encoded video.
For Time-Lapse Mode Recording Time, please refer to Appendix B.
1.2.4 Motion Detection
The digital video recorder continuously monitors all camera inputs for
motion. When motion is detected, the system reacts according to the
motion action set by the administrator, including increase of
recording frame rate, sounding the buzzer, triggering the alarm output,
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 and main TV monitor display either live camera
pictures or pictures from hard disks. The display resolution is
640x480 for NTSC or 800x600 for 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.
The call monitor displays full screen images of cameras associated with
alarms or images from the installed cameras sequentially. It is based
on switched analog camera input.
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 and/or
TV monitor, just like in live video mode.
