ii. 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.
High produces the highest image quality, but increases the file size. Low produces the
lowest image quality and decreases the file size.
c. 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.
d. Move the Frame Rate slider to the desired value. The choice of frame rates depends on the
combination of the selected resolutions for the selected streams. The maximum frame is
displayed by default. The higher the FPS, the smoother the motion in the video.
e. Do one of the following:
·
·
·
·
4. Repeat the above steps for Stream2 and Stream3.
5. Click Save.

If you selected MJPEG, continue with step 4.
If you selected H.264, Rate Control is displayed. It is pre-configured and
cannot be changed. Configure the following settings:
Set the Max Bit Rate to a value between 64 to 20000. The default settings are
3795 kbps for Stream1, 1382 kbps for Stream2, and 750 kbps for Stream3.
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.
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.
