
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.

Resolution: System supports various resolutions, you can select from the dropdown
list. Please note the option may vary due to different series.

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:
normal/HDCVI. For normal mode, the audio signal is from the Audio In port. For
HDCVI mode, the audio signal is from the coaxial cable of the camera.
 Audio sampling rate: The audio sampling rate refers to the device audio sampling rate
per second. The options include: 8/16K. The higher the rate is, the more natural and
