Click the stream item to display the detailed information� The maximum frame size will follow your
settings in the above Viewing Window sections (streams #1).
This Network Camera provides real-time H.264, MPEG-4 and MJPEG compression standards (Triple
Codec) for real-time viewing�
If H.264 / MPEG-4 mode is selected, the video is streamed via RTSP protocol� There are four parameters
for 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
NOTE that for streams featuring the 1280x800 frame size, the maximum frame rate is either 30 or
25fps depending on how you configure the power line frequency (NTSC: 60Hz or PAL: 50Hz)� The
maximum frame rate for JPEG and lower frame sizes (720P and under) is 30fps in NTSC and 25fps in
PAL�
This limits the maximum refresh frame rate per second� Set the frame rate higher for smoother video
quality�
