Three options exist for the video display: 176 x 120,
352 x 240, and 704 x 480. In 704x480 mode, the
frame rate will be reduced to 10 fps and increased
to 30fps automatically when it is switched back to a
lower image size.
Limits the maximum refresh frame rate. The frame
rate is used with the Video quality control setting
(below) to optimize bandwidth utilization and video
quality.
Sets the key frame interval. Selecting a higher
interval will decrease bandwidth utilization. If you
have a bad network connection, use a lower interval
to minimize the loss of image frames.
To fix the bandwidth utilization regardless of the
video quality, choose Fix bit rate and select the
desired bandwidth. The video quality may be reduced
in order to send maximum frames with limited
bandwidth, especially when images change
drastically. For higher video detail regardless of the
bandwidth selection, select Fix quality and select
a quality level. This setting will utilize more bandwidth
to send the maximum frames when images change
drastically.
Vertically rotate the video.
Horizontally rotate the video. Check both flip and
mirror if the DCS-3220 is to be installed upside
down.
If the camera works in a multi-user environment,
the user can select this to conserve bandwidth by
reducing video capture rate.
