60 - User's Manual

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,

we sugguest you set up the IP8330 in an environment with sufcient ambient light source. In addition,

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

time) at 1/60s.
