4.2.2 Video/Audio

Go to "Video configuration" "Video/Audio" to see an interface as shown below.
→
Three video streams are available. You can set each one of them differently with the
limitations of the camera's capabilities.
Resolution: The higher the resolution is, the bigger the image is.
Frame rate: The higher the frame rate is, the more fluent the video is. However, more storage
room will be taken up.
Bitrate type: CBR and VBR are available. CBR (Constant Bit-Rate) means that no matter how
what the video resources are, the compression bitrate will be constant as configured. This will
not only facilitate the image quality better in a constant bitrate but also help to calculate the
capacity of the recording. VBR (Variable Bit-Rate) means that the compression bitrate can be
automatically adjusted according to the change of the video resources with the configured
bit-rate as the maximum value. This will help to optimize the storage network bandwidth.
Video Quality: When VBR is selected, you need to choose image quality. The higher the image
quality you choose, the more bitrate will be required.
Bitrate: Please set it according to your needs while taking in consideration the bandwidth and
storage limits.
I Frame interval: It is recommended to use the default value. If the value is too high, the read
speed picture group will be slow resulting in video quality loss.
Video Compression: Choose between H.265 and H.264. The IPC also support MJPEG on
sub-stream resolution but you need to make sure that the application connected to the
camera also supports it.
Profile: Baseline, main profile and high profile are optional. Baseline profile is mainly used in
interactive applications with low complexity and delay. The main or high profile is mainly used
for higher coding requirements.
Send Snapshot: Please select it according to the actual situation.
Video encode slice split: If enabled, you may get a more fluent image even when using a
low-performance PC.
Watermark: You can set a watermark that will appear on the image.
