I Only / IP Only
IP - Simple Profile - Medium bit rates for same quality. I - Highest bit rates for same quality.
**When choosing MJEPG streaming, ONLY support “I Only” mode
¾Bit rate Type
Constant and Variable bit rates control allows flexibility in choosing how much bandwidth is available on network and quality of video required.
¾Constant Bit rates
3M / 2M / 1.5M / 1M / 750K / 500K / 384K / 256K / 128K / 64K / 32K
¾Variable Bit rates
2 ~ 31 (quality is best in case value is “3”)
¾Frame per Second.
1 ~ 30
¾Group Size
Adjusts the ration between “I” frames and “P” frames. Lower the group size, better the quality.
