Section 3 - 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 MJPEG.
Frame Size: Select proper frame size for different viewing devices; a 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 12
options (including different frame rates) you can select from: 352x240, 640x480,
720x480, 800x600, 1024x768, 1280x720, 1280x1024, 1920x1080, and 2048x1536 if
there is no viewing window applied.
Maximum Frame Rate: This option affects the smoothness of the video. You can
select a higher frame rate for smoother video quality, but it will require 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 where the 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. Enter a number for the intra frame
period from 2 to 64 frames in the text box. (higher number = lower quality)
Video Quality: This setting limits the maximum refresh frame rate.
• Constant bit rate: To set a fixed bandwidth regardless of the video quality, select
this and the desired bandwidth from 64 Kbps to 8 Mbps. You can also select
Customize and manually enter a value.
• 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.
