Three options exist for two sizes of video display:
Normal
is the default video display mode.
Half
is a quarter size of
Normal
.
Text will be displayed in the black bar above the video
window with the timestamp. The timestamp is
captured from the date and time of the
DCS-5300W
and is maintained by a built-in real-time clock.
Select the option for color or monochrome video

Select either an internal or external microphone as
the audio source. If you choose to use an external
microphone, connect it to the microphone
connection at the rear of the

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 video quality level. This setting will utilize more
bandwidth to send the maximum frames when
images change drastically.

My priority is clear identification for each image
To have the best video quality, you should set
Fix quality
to
detailed
or
excellent
and tune the
Maximum frame rate
to suit
your network bandwidth. If you get
some broken pictures in a slow network, you can set
TCP protocol
in
Connection type
for a more accurate transmission but the received images
may have a lag. Note that any slow connection with multiple users will impair
performance.
Recommendations for setting video for the best
performance:
“Best performance” means the image refresh rate should be the fastest possible
and the video quality should be the best possible at the lowest network bandwidth
possible. Three factors,
Maximum frame rate
,
Fix bit rate
, and
Fix quality
in
the
Video Configuration
page, are related to performance.
My priority is real-time motion images
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 set
Fix bit Rate
to 1000Kbps or
1200Kbps, or set
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
Half
in size option for better images or
Half x 2
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.

Recommendations for setting video for the best
performance (continued):
I want to compromise between real-time and clear images
If you have a broadband network, set
Fix quality
to
Good
image quality, or
higher,
instead of setting the
Bit rate
. Otherwise, fix the bit rate according to
your actual network speed and set the frame rate to 30. If the image quality is
low, select a lower frame rate above 15. If the image quality is still not improved,
select a lower bit rate.

are all adjusted in the same
manner. For each video compensation you can set from among eleven levels
ranged from -5 to

The default setting is zero for each adjustment.
You may press
to fine-tune the image and see what affect the setting
will have on the image. When the image is acceptable, press
to store the

to recall the original settings. If settings are changed
without saving, they will be used until the next system start-up.
