Configuration
Video Quality Setting for Stream 1~4
Compression Type:
The compression level affects 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 different 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 13
options you can select: from 1280x800 to 176x144.
Frame Rate:
This option affects 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, 2, 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.)
Intra Frame Period:
Determines the frequency and I frame is planted. The shorter
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.
• Constant bit rate:
To set a fixed bandwidth regardless of the video quality,
select Constant bit rate and the desired bandwidth from 20 Kbps to 6 Mbps.
• Fixed quality:
To optimize the bandwidth utilization and video quality. The
video quality can be adjusted to the following setting: Medium, Standard, Good,
Detailed and Excellent.
