User's Manual - 59

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

Thislimitsthemaximumrefreshframeratepersecond.Settheframeratehigherforsmoothervideo

quality.

For IP8332:

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

Customize and manually enter a value. The frame rate will decrease if you select a higher resolution.

For IP8330:

Itsupportsupto60fps@640x480.Ifyouwanttoviewsmoothandcrystalclearvideowith60fps,

please manually select maximum frame rate at 60fps and set the shutter time (maximumexposure

time) at 1/60s.
