Video Quality Setting for Stream 1~4
Compression Type: The compression level aects the amount of bandwidth
and storage required. Lower compression uses more bandwidth and storage but
delivers better image quality. Of the three options, H.264 consumes much less
network bandwidth compared to MPEG4 and JPEG.
Frame Size: Select proper frame size for dierent viewing devices, bigger frame
size requires more bandwidth and storage usage. For smaller viewers, such as
mobile phones, a smaller frame size and lower frame rate is recommended.
There are 5 options you can select: 176x144, 320x240, 640x480, 1280x720
1360x768,1600x940,1920x1080, if there is no viewing window applied. (176x144 for
mobile phone, 640x480 for VGA display, 1280x720 for HD display).
Frame Rate: This option aects the smoothness of the video. Select higher frame
rate for smoother video quality but it requires more storage usage. 10 options for
selection: customize, 1, 3, 5, 8, 10, 15, 20, 25, 30 fps (30 fps is recommended real-
time video on a computer monitor. 5 fps is ideal for mobile viewers.)

the duration, the more likely you will get better video quality, but at the cost of
higher network bandwidth consumption. Select the intra frame period from the
following durations: 1/4 second, 1/2 second, 1 second, 2 seconds, 3 seconds and 4
seconds.
Video Quality: This setting limits the maximum refresh frame rate.
