The extra stream supportsH.264, MJPG.Resolution The resolution here refers to the capability of the networkcamera.Frame Rate PAL：1～25f/s；NTSC：1～30f/s.Bit Rate Main stream: User may set bit rate here to change videoquality. The large the bit rate is, the better the quality is.Please refer to recommend bit rate for the detailedinformation. Extra stream: In CBR, the bit rate here is the max value.In dynamic video, system needs to low frame rate orvideo quality to guarantee the value. The value is null inVBR mode.Reference bitrateRecommended bit rate value according to the resolution andframe rate you have set.I Frame Here user may set the P frame amount between two I frames.The value ranges from 1 to 150. Default value is 50.Recommended value is frame rate *2.WatermarkenableThis function allows you to verify the video is tampered or not.Here user may select watermark bit stream, watermark modeand watermark character.
