8.1 Set Video Encoding Parameters
Set video encoding parameters to adjust the live view and recording effect.
● When the network signal is good and the speed is fast, you can set high resolution and bitrate to
raise the image quality.
● When the network signal is bad and the speed is slow, you can set low resolution, bitrate, and
frame rate to guarantee the image fluency.
● When the network signal is bad, but the resolution should be guaranteed, you can set low
bitrate and frame rate to guarantee the image fluency.
● Main stream stands for the best stream performance the device supports. It usually offers the
best resolution and frame rate the device can do. But high resolution and frame rate usually
means larger storage space and higher bandwidth requirements in transmission. Sub-stream
usually offers comparatively low resolution options, which consumes less bandwidth and
storage space. Third stream is offered for customized usage.
Steps
Note
The supported parameters vary with different models. The actual device prevails.
1. Go to Configuration → Video → Video Encoding → Video Encoding.
2. Set the parameters for different streams.
Stream Type
Select the stream type according to your needs.

Bitrate
Select relatively large bitrate if you need good image quality and effect, but more storage
spaces will be consumed. Select relatively small bitrate if storage requirement is in priority.
Frame Rate
It is to describe the frequency at which the video stream is updated and it is measured by
frames per second (fps). A higher frame rate is advantageous when there is movement in the
video stream, as it maintains image quality throughout.
Resolution
The higher the resolution is, the clearer the image will be. Meanwhile, the network
