User's Manual - 53

If JPEG mode is selected, the Network Camera sends consecutive JPEG images to the client,

producing a moving effect similar to a lmstrip. Every single JPEG image transmitted guarantees

the same image quality, which in turn comes at the expense of variable bandwidth usage� Because

the media contents are a combination of JPEG images, no audio data is transmitted to the client.

There are three parameters provided in MJPEG mode to control 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�

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�

■ Video quality

The video quality can be adjusted to the following settings: Medium, Standard, Good, Detailed,

and Excellent� You can also select Customize and manually enter a value�

NOTE

►

If you congure a Customized value for the Fixed Quality setting in Video quality, the value will

then represent the compression rate� In here, a lower value will produce higher quality�

►

Converting high-quality video may signicantly increase the CPU loading, and you may encounter

streaming disconnection or video loss while capturing a complicated scene� In the event of such

occurance, we suggest you customize a lower video resolution or reduce the frame rate to obtain

smooth video�
