www.foscam.us www.foscam.us Figure 4.47 Stream type: There are four types to identify different streams you have set. Resolution: The camera supports four types: 720P, 960P, VGA, QVGA. 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. 4.4.2 On Screen Display This page is used to add timestamp and device name on the video.

Figure 4.47
Stream type:
There are four types to identify different streams you have set.
Resolution:
The camera supports four types: 720P, 960P, VGA, QVGA. 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.
