Stream type: There are four types to identify different streams you have set.

Resolution: The camera supports multiple types, For example: 960P, 720P, VGA. The higher the resolution is,

the clearer video will become. But the code flux will become larger too, and it will take up more bandwidth.

(Different models support different specific types. )

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. When 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

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.
