Stream type: There are four types to identify different streams you have set.
Resolution: The camera supports multiple types. 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. (The maximum
frame rate for each model is different. )
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. You should lower frame rate when
the bandwidth is limited. Normally, when the frame rate above 15, you can achieve fluently video.The
maximum frame rate for each model is different.
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.
Variable Bitrate: The two options are Yes and NO. Select Yes the bit rate is variable, and the highest
value isn't higher than Bit Rate Value (2Mbps). Select NO and the bit rate is constant with Bit Rate Value
(2Mbps).
