4.2.2 Encode bar
For encode bar, see Figure 4-4.
● Main Stream: It has large bit stream value and image with high resolution, but also requires large
bandwidth. This option can be used for storage and monitoring. For details, see "4.5.2.1 Video".
● Sub Stream: It has small bit stream value and smooth image, and requires less bandwidth. This
option is normally used to replace main stream when bandwidth is not enough. For details, see
"4.5.2.1 Video".
● Protocol: You can select the network transmission protocol as needed, and the options are TCP,
UDP and Multicast.
Before selecting Multicast, make sure that you have set the Multicast parameters.
