If you select
MJPEG
, the following fields are displayed:
a. From the
Quality Level
drop-down list, select
High, Mid,
or
Low
. The default is
Mid
.
Low
produces the highest image quality, but increases the file size.
High
produces
the lowest image quality, but decreases the file size.
In the
DSCP
text box, enter a value between
0-63
. The default DSCP value is
0
(DSCP disabled).
The DSCP (Differentiated Services Code Point) value defines the priority level or QoS
(Quality of Service) for the specified type of traffic. The higher the value that is entered,
the higher the priority, which reduces network delay and congestion. The camera
supports the Video DSCP class, which consists of applications such as HTTP,
RTP/RTSP, and RTSP/HTTP.
Note:
Remember to synchronize the QoS setting of the camera with the network router.
Move the
Frame Rate
slider to a value between
1-30
for NTSC or
1-25
for PAL systems.
The maximum frame is displayed by default. The higher the FPS, the smoother the
motion in the video.
The
Rate Control
is pre-configured and cannot be changed.
Note:
The
Rate Control
setting is displayed only when
H.264
is selected.
Set the
Max Bit Rate
to a value between
64
to
20000
. The default settings are
3110
kbps for
1080p, 1382
kbps for
720p,
and
750
kbps for
D1.
The higher the bit rate, the
better the image quality. Set the maximum bit rate high enough to allow for a high
instantaneous bit for more complex video. A higher bit rate consumes more storage
space.
Note:
The
Max Bit Rate
setting is displayed only when
H.264
is selected.
Set the
Encoding Priority
. This function enables the user to adjust the quality of the
picture along a single axis. The slider ranges from
1
(low bit rate) to
10
(high picture
quality). The default setting is
7
.
The slider is configured based on Quantization Parameter (QP) values. Setting QP to a
high value increases the bit rate and results in high compression, but this is at the
expense of poor decoded image quality. Setting QP to a low value results in better
decoded image quality, but with lower compression.
