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 select a quality level you prefer�
NOTE:
NOTE
► 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 such
occurance, we suggest you customize to a lower video resolution or reduce the frame rate to obtain
smooth video�
