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.
Resolution: For analog channel, system supports various resolutions, you can
select from the dropdown list. Please note the option may vary due to different
series. For digital channel, the resolution here refers to the capability of the
network camera.
Frame rate: It ranges from 1f/s to 25f/s in NTSC mode and 1f/s to 30f/s in
PAL mode.
Bit rate type: System supports two types: CBR and VBR. In VBR mode, you
can set video quality.
Quality: There are six levels ranging from 1 to 6. The sixth level has the
highest image quality.
Video/audio: You can enable or disable the video/audio.
Audio format: Please select from the dropdown list. There are three options:
G711a/G711u/PCM.
Audio source: Please select from the dropdown list. There are two options:
local/HDCVI. For local mode, the audio signal is from the Audio In port. For
HDCVI mode, the audio signal is from the coaxial cable of the camera.
