2.3 Stream configuration
Click features list on the left, select "Stream configuration”, then you can configure stream video for
the current IP equipment. As the following figure shows：
Each device can be configured for different video stream; each device can be configured with up to
three different video streams. This let you set a high quality recording stream and perhaps a low level
stream for remote monitoring.
Resolution: According to the actual resolution to actual resolution of IP equipment
divided :into :1920x1080/1280x960/1280x720/1600x1200/D1/CIF/QCIF etc.
Frame rate：PAL can be up to 25fps and NTSC up to 30fps
I Frame interval：time interval between I frames divided into 1/2/3/ seconds three types，for higher bit
rate of the screen, should shorten frame spacing. The smaller frame interval, it is good to increase
position accuracy of video return, and advantageous to the network video when the recovery of shaking.
If frame interval become small, the video streaming will become big, unless understand the reason the
default value 2 should be used.
Bit Rate：Either CBR or VBR. CBR is constant bit rate, where the daa streamed will be at a constant
value.；VBR that is variable bit rate, where compression data can change relative to the complexity of the
compression of the scene, relative to the quality setting below.
Quality: Value 1-9 choose within quality. The higher the quality values the clearer images will.
Hint: setting a high quality value and a small VBR bitrate may not provide the ideal settings. Unless
required a quality setting of 7 is acceptable.
2.4 Route Mapping
Through the routing mapping IP equipment can be realized to WAN network requests through a
router.
