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.
It is to set video resolution. The higher the resolution is, the better the video
quality is.
PAL：1～25f/s；NTSC：1～30f/s.
Main stream: You can set bit rate here to change video quality. The
large the bit rate is , the better the quality is. Please refer to
recommend bit rate for the detailed information.
Extra stream: In CBR, the bit rate here is the max value. In dynamic
video, system needs to low frame rate or video quality to guarantee
the value. The value is null in VBR mode.
Recommended bit rate value according to the resolution and frame rate you
have set.
Here you can set the P frame amount between two I frames. The value
ranges from 1 to 150. Default value is 50.
Recommended value is frame rate *2.
It includes G711a/G711u/PCM.
Please select from the dropdown list. There are two options: Normal/HDCVI.
In the normal mode, the audio signal comes from the Audio In. In the HDCVI
mode, the audio signal comes from the coaxial cable of the camera.
This function allows you to verify the video is tampered or not.
Here you can select watermark bit stream, watermark mode and watermark
character. Default character is DigitalCCTV. The max length is 85-digit. The
character can only include number, character and underline.
Step 3 Click Save to complete the setup.
