Video
This section allows you to configure Video stream settings, On screen display and Snapshot
settings.
3.4.1 Settings
Stream type: There are four types to identify different streams you have set.
Resolution: The camera supports two types: 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.
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.
