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�
