VIVOTEKVideo quality <strong>se</strong>ttings for stream 1 / stream 2 Advanced ModeThe Network Camera offers two choices of video compression standards for real-time viewing: MPEG-4and MJPEG.Click the items to display the detailed configuration <strong>se</strong>ttings. You can <strong>se</strong>t up two <strong>se</strong>perate streams for theNetwork Camera for different viewing devices. For example, <strong>se</strong>t a smaller frame size and lower bit ratefor remote viewing on mobile phones and a larger video size and a higher bit rate for live viewing on webbrow<strong>se</strong>rs.If MPEG-4 mode is <strong>se</strong>lected, it is streamed in RTSP protocol. There are four parameters provided inMPEG-4 mode which allow you to adjust the video performance:■ Frame sizeSelect the video size. Note that a larger frame size takes up more bandwidth. The frame sizes are<strong>se</strong>lectable in the following resolutions: 176 x 144, 320 x 240 and 640 x 480.■ Maximum frame rateThis limits the maximum refresh frame rate per <strong>se</strong>cond. Set the frame rate higher for smoother videoquality.If the power line frequency is <strong>se</strong>t to 50Hz, the frame rates are <strong>se</strong>lectable at 1fps, 2fps, 3fps, 5fps,8fps, 10fps, 15fps, 20fps, and 25fps. If the power line frequency is <strong>se</strong>t to 60Hz, the frame rates are<strong>se</strong>lectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps, and 30fps.
