The Network Camera offers two choices of video compression standards for real-time viewing, so you
can choose MPEG-4 or MJPEG for dual streams�
Click the items to display the detailed configuration settings. You can set up two seperate streams for the
Network Camera for different viewing devices. For example, set a smaller frame size and lower bit rate
for remote viewing on mobile phones and a larger video size and a higher bit rate for live viewing on web
browsers�
If
MPEG-4
mode is selected, the video is streamed via RTSP protocol� There are four parameters
provided in MPEG-4 mode which allow you to adjust the video performance:
■ Frame size
Select the video size. Note that a larger frame size takes up more bandwidth. The frame sizes are
selectable in the following resolutions: 176 x 144, 360 x 240, 640 x 480, and 800 x 600�
■ Maximum frame rate
This limits the maximal refresh frame rate per second� Set the frame rate higher for a smoother video
quality�
If the power line frequency is set to 50Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps,
8fps, 10fps, 15fps, 20fps, and 25fps. If the power line frequency is set to 60Hz, the frame rates are
selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps, and 30fps� You can also select
