4.11.1.3 Encode
It is to set video bit stream, picture bit stream, video overlay parameter and etc.
4.11.1.3.1 Video
Video setting includes the following items. See Figure 4-74.
Channel: Select the channel you want.
SVC: SVC is so called scaled video coding. Check the box to enable this function.
During the network transmission process, system discards unimportant frames when
the bandwidth is not sufficient or the decode capability is low. It is to guarantee video
quality and transmission fluency.
Type: Please select from the dropdown list. There are three options: regular/motion
detect/alarm. You can set the various encode parameters for different record types.
Compression: System supports H.264H, H.264, H.264B, and MJPEG.
H.264H: It is the High Profile compression algorithm. It has the high encode
compression rate. It can achieve high quality encode at low bit stream. Usually
we recommend this type.
H.264 is the general compression algorithm.
H.264B is the Baseline algorithm. Its compression rate is low. For the same video
quality, it has high bit stream requirements.
Smart codec: Select Start from the dropdown list to enable smart codec function. The
DVR can auto reduce the video bit stream of the non-important surveillance object to
save the storage space.
