Video Setup, please click "Video"
1) 720p120
Optional items: On, Off
2) Video format
Support 50HZ(PAL)and 60HZ(NTSC),
and Dial priority three formats.
3) Encode Level
Support baseline, mainprofile, highprofile
three formats.
4) Encode Protocol
Support H.264 and H.265 and MJPEG three
formats.
5) Resolution
First bit flow support 1920x1080,1280x720,
1024x576,960x540,640x360,Second bit flow
support 720x480,720x576,480x270,320x240,
640x360, the bigger resolution is, the clearer the
image will be, more network bandwidth will be
taken.
6) Bit Rate
User can assign bit flow/stream, normally
speaking, the bigger bit flow is, the clearer the
image will be. The bit allocation must combine
with network bandwidth, when the network
bandwidth is too narrow and the allocated bit flow
is too big, will cause video signal flow not to be
transmitted normally, the video effect will be
worse.
7) Frame rate
User can specify the size of the frame rate,
generally, the frame rate greater, the image more
smooth; Frame rate is smaller, the more sense of
beating.
8) I key frame interval:
Set interval between 2 I frame, the bigger
interval is, the response will be lower from
viewing window.
9) Bit Rate control
Code stream control way:
