Sets the frame rate of the current video. In the [PAL] system, some models support 50
frames, and the maximum support is 25 frames when the wide dynamic mode is turned
Frame Rate
on. [NTSC] under the system, some models support 60 frames, and when the wide
dynamic mode is turned on, the maximum support is 30 frames.
The video set to [frame rate first] is smoother and the video set to [quality first] is
Priority
clearer.
The number of frames between every two I frames can be set, and the range can be

10-100.
Set constant rate or variable rate compression. At the fixed bit rate, the amount of
video data fluctuates little, and the bandwidth occupied by the network transmission is
Ecoding Mode
stable; at the variable bit rate, the amount of video data changes with the complexity of
the video picture, and the bandwidth is saved when the scene is single. In the case of
variable bit rate, there are several levels. If the better, the higher the average bit rate is.
The screen is rotated 90 degrees to adapt to the scene where the device is installed on

the wall. It is off by default.
Set how video is encoded. H. 265 encoding saves bandwidth, but some browsers or
Video Encoding
playback software do not support h.265.
Switch S + on and off can be selected from the drop-down list. When S + is enabled,
S+
functions such as compression mode, video quality, I-frame frame rate and key area
will not be available.

When [SVC] is turned on, P frame can be encoded as non reference frame, which can
be used for frame extraction video recording and save storage space. The video file
after frame extraction still supports normal decoding. When the [auto] mode is
SVC
selected, the device will adapt to the current network environment and decide whether
to send the frame to ensure that the image can be previewed normally during preview.
