Chapter 5: DVR Setup - 5.5 Recording Frame Rate
Recording frame rate will affect the movement of objects in recorded video. More frames
per second gives smoother movement and uses more hard disk space.
System default value is 30fps (frames per second) for NTSC (PAL is 25fps), which means
the system will record 30 frames per second shared by all cameras. User can set frame rate
for NTSC to 30,15,10,7,5,4,3,2,1 frames per second (PAL is 25,12,8,6,4,3,2,1)
There are three levels of recording quality, High, Normal, and Low.
Higher quality uses more hard drive space.
Record frame rate, record quality and available hard drive space will affect
the total recording time of the DVR system.
