 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 resolution of 960 × 1080 (1080P Lite) is avaiable when the 1080P Lite is enabled in the
Record>Advanced Settings interface (refer to Chapter5.11 Configuring 1080P Lite).
