Dynamic DNS (DDNS)
Dynamic DNS (Domain Name Service) is a method of keeping a domain name
linked to a changing (dynamic) IP address. With most Cable and DSL
connections, you are assigned a dynamic IP address and that address is used
only for the duration of that specific connection. With the
DCS-3220
, you can
set up your DDNS service and the
DCS-3220
will automatically update your
DDNS server every time it receives a different IP address. Depending on the
service, this update may take a few hours.
UDP Video port -
Can be set to a port other than the default port
5003. A corresponding port must be opened on
your firewall.

Universal PnP
UPnP is short for Universal Plug and Play, which is a networking architecture
that provides compatibility among networking equipment, software, and
peripherals. The
DCS-3220
is a UPnP enabled internet camera. If your operating
system is UPnP enabled, the device will be easier to configure. If you do not
want to use the UPnP functionality, it can be disabled by unselecting the Enable
UPnP check box.

Maximum frame rate-
Video quality control-
Flip -
Vertically rotate the video.
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.
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.

Key frame interval-
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.

If the camera works in a multi-user environment,
the user can select this to conserve bandwidth by
reducing video capture rate.
Horizontally rotate the video. Check both

To achieve a real-time visual effect, the network bandwidth should be large
enough to transmit 20 image frames per second (fps) or more. If you are on a
broadband network over 1 Mbps, you can choose
Fix bit Rate
to 1000Kbps or
1200Kbps, or choose
Fix quality
to achieve the maximum frames. The maximum
frame rate is 25 in 50Hz system and 30 in 60Hz system. If your network bandwidth
is more than 384Kbps, you can adjust
Fix bit rate
according to your bandwidth
and set the maximum frame rate of 25 to 30. If the images vary dramatically in
your environment, you may slow down the maximum frame rate to 20 to decrease
the transmitted data for better video quality. Since the human eye could not
easily differentiate between 20 and 25 or 30 frames per second, the slower
frame rate will not be noticed. If your network bandwidth is below 384 Kbps, you
should adjust the bit rate according to your bandwidth and experiment to allow
for the best frame rate that can be achieved. The faster frame rate in a slow
network will blur the images. You may also try to choose
352x240
in size option
for better images or
704x480
for larger image size. Because the network has
burst constraints and everyone’s environment is not the same, any poor
connection will impair normal performance.
Recording Settings for real-time motion images
“Best performance” means the image refresh rate should be the fastest possible
and the video quality should be the best possible using the lowest amount of
network bandwidth possible. Four factors,
Maximum frame rate
,
Key frame
interval
,
Fix bit rate
, and
Fix quality
in the Video configuration page, are
related to the performance.
