58 - User's Manual

If JPEG mode is selected, the Network Camera continuously sends 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

Select the video size� Note that a larger frame size takes up more bandwidth� The frame sizes are

selectable in the following resolutions: 176 x 144, 320 x 240, and 640 x 480.

■ 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�

■ 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�
