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 the 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 six
options you can select: 384 X 216, 640 X 360, 1280 X 720, 1360 X 768, 1600 X 904,
or 1920 X 1080.
Frame Rate: This option affects how smooth the video is. Select a higher frame
rate for smoother video quality but it requires more storage usage. There are 10
options to select from: 1, 3, 5, 8, 10, 15, 20, 25, 30 fps (30 fps is recommended for
real-time video on a computer monitor; 5 fps is ideal for mobile viewers), or select
Customize to manually enter a value.
Intra Frame Period: Determines the frequency when an I frame is inserted. The shorter
the duration, the better the video quality is but will require higher bandwidth and
storage space. Select from the following durations: 1/4 second, 1/2 second, 1 second,
2 seconds, 3 seconds, or 4 seconds.
Video Quality: This setting limits the maximum refresh frame rate.
• Constant bit rate: Select to set a fixed bandwidth regardless of the video quality
and choose a bandwidth value from the drop-down menu. You can also select
Customize to manually enter a value.
• Fixed quality: Select to optimize the bandwidth utilization and video quality. The
video quality can be adjusted to one of the following settings: Medium, Standard,
Good, Detailed, and Excellent. You can also select Customize and manually enter
a value.
