Click the stream item to display the detailed information This Network Camera offers real-time MPEG-4
and MJEPG compression standards (Dual Codec) for real-time viewing.
The MD7530/7530D supports dual streams with frame size ranging from 176 x 144 to 640 x 480.
The MD7560/7560D supports multiple streams with frame size ranging from 176 x 144 to 1600 x 1200.
The maximum frame size will follow your settings in the above Viewing Window sections.
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
You can set up different video resolution 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� Note that a larger frame size takes up more bandwidth�
■ Maximum frame rate
This limits the maximum refresh frame rate per second. Set the frame rate higher for smoother video
quality�
