sampling rate. When the video is complex, the captured bit and retrieved bit are more,
that will make the video data files increase. On the contrary, if the video is simply, that
will collect less bit to storage. In other words, the whole audio and video sampling rate
aren’t same. If you choose the CBR, from start to finish are all maintain a certain bit rate.
For 5 minutes of image data, if take 512kbps sampling rate to calculate. That is
equivalent to 19200k
(
5x60x512/8
)
.The advantage is compression speed quickly; VBR
the flow per second can changeable, the advantage is to record with more capacity in
the complex signal, when the wave simple, it can with low flow rate to effective use of
space. The disadvantage for CBR is that the flow are all same per second, it is easily to
waste of space.
(3.3)Recording time
Set up each channel the Pre-alarm record time and Post-alarm
record time.
(3.4)OSD Display
Set up each Channel Name and Time Stamp if need to display
for recording, and the directly adjust position for mouse to drag
and drop.
(Note: The definition for this function setup is
different from the location of live monitor for Date & Time and
Channel name.)
