Description

You can select the channel for the IP Cameras.
Stream
You can set the value of Resolution, Bit Rate, Frame Rate, Key Frame
Interval when the video was set the main stream.
Resolution
The resolution of the IP Camera.
The higher the resolution is,the sharper the video quality is, but also with
the increasing stream, which will take up the higher bandwidth.
Bit Rate
Generally speaking, the larger the bit rate is, the clearer video will become.
But the bit rate configuration should combine well with the network
bandwidth. If the bandwidth is very narrow, and bit rate is large, that will
lead to video can not play well.
Frame Rate
Note that a larger frame size takes up more bandwidth.
When the video format is 50Hz, the maximum frame rate is 25 fps.
When the video format is 60Hz, the maximum frame rate is 30 fps.
You should choose a lower frame rate when the bandwidth is limited.
Normally, when the frame rate above 15, you can achieve fluently video.
Key Frame
Interval
The time between last key frame and next key frame. The shorter the
duration, the more likely you will get a better video quality, but at the cost of
higher network bandwidth consumption.
