Adjust the sensitivity of the motion detector. The higher the value, the finer the sensitivity is detected.
When it detects a motion, a green triangle mark would appear at the upper left corner of the screen.
(5) Video Detection
Adjust the intensity of the audio detector. The system detects sound when it exceeds the intensity
value.
(6) Quality
Adjust the video quality. The higher the value, the lower the compression level and uses more hard
disk space.
(7) Frame Rate
Set the maximum number of frames to be recorded during motion and motionless state. The frame
rate ranges from 1 to 30 for NTSC and 1 to 25 for PAL. The higher the frame rate, it uses more hard
disk space.
(8) Video Size
Select the size of the video and click the  button. The higher the size, the larger the file it create.
(9) Mask/Shield Edit
Mask, mark an area on the screen to disregards the motion in the marked area and to only monitor

check box. Click and drag a frame on the screen to create Mask area.
(10) Compression Type
User can refer the table below to check the NV card supports what type of compression. H264 is the
latest and advanced video compression format that delivers better video quality and smaller file size
but this uses more CPU resource. Advanced MPEG4 and MJPEG, both provide a standard for color
picture compression rate. MPEG4 uses higher compression rate and smaller file size. While MJPEG
uses slightly lower compression rate and bigger file size.
