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

a moving effect similar to a filmstrip� 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

►

Video quality and fixed quality refers to the compression rate, so a lower value will produce higher

quality�

►

Converting high-quality video may significantly increase the CPU loading, and you may encounter

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

we suggest you customize a lower video resolution or reduce the frame rate to obtain smooth video�
