Averaging period
Select the appropriate averaging period as a means of stabilizing
the long term bit rate.
I-frame distance
Use the slider to set the distance between I-frames to Auto or to
between 3 and 60. An entry of 3 means that every third image is
an I-frame.The lower the number, the more I-frames are
generated.
Min. P-frame QP
In the H.264-protocol, the Quantization Parameter (QP)
specifies the degree of compression and thus the image quality
for every frame. The lower the QP value, the higher the encoding
quality. A higher quality produces a higher data load. Typical QP
values are between 18 and 30. Define the lower limit for the
quantization of the P-frames here, and thus the maximum
achievable quality of the P-frames.
I/P-frame delta QP
This parameter sets the ratio of the I-frame QP to the P-frame
QP. For example, you can set a lower value for I-frames by
moving the slide control to a negative value. Thus, the quality of
the I-frames relative to the P-frames is improved. The total data
load will increase, but only by the portion of I-frames.
To obtain the highest quality at the lowest bandwidth, even in
the case of increased movement in the picture, configure the
quality settings as follows:
1.
2.
3.

Observe the coverage area during normal movement in the
preview images.
Set the value for Min. P-frame QP to the highest value at
which the image quality still meets your needs.
Set the value for I/P-frame delta QP to the lowest possible
value. This is how to save bandwidth and memory in normal
scenes. The image quality is retained even in the case of
increased movement since the bandwidth is then filled up
to the value that is entered under Maximum bit rate.
