If the configured encoding resolution conflicts with the resolution of
the front-end camera, the encoding parameters will adjust
automatically to meet the front-end camera. E.g., if the resolution of
the front-end camera is 720p, then the encoding resolution of the
main stream will adjust to 720p automatically.
The 960 × 1080 (1080p Lite) resolution is available when 1080p Lite
is enabled in the Record > Advanced Settings interface.
- Bitrate Type: Set the bitrate type to be Variable or Constant.
- Video Quality: Set the recording video quality, with six levels configurable.

nable H.264+ or Enable H.265+ checkbox to enable this function. Enabling it helps to
ensure high video quality with a lowered bitrate.
