Configuring the IP AutoDome en 79

 

 

CAUTION!

Change the profiles only once you are fully familiar with all the configuration options. In the default setting, Stream 1 is transmitted for alarm connections and automatic connections. Bear this fact in mind when assigning the profile.

NOTICE!

All parameters combine to make up a profile and are dependent on one another. If you enter a setting that is outside the permitted range for a particular parameter, the nearest permitted value will be substituted when the settings are saved.

Profile name

You can enter a new name for the profile. The name is then displayed in the Default profile list field on the Encoder Streams page in the lists of selectable profiles.

Target data rate

You can limit the data rate for the IP AutoDome to optimize utilization of the bandwidth in your network. The target data rate should be set according to the desired picture quality for typical scenes with no excessive motion.

For complex images or frequent changes of image content due to frequent movements, this limit can be temporarily exceeded up to the value you enter in the Maximum data rate field.

Maximum data rate

This maximum data rate is not exceeded under any circumstances. Depending on the video quality settings for the I and P-frames, this fact can result in individual images being skipped. The value entered here must be at least 10% higher than the value entered in the Target data rate field. If the value entered here is too low, it will automatically be adjusted.

Encoding interval

The setting selected here determines the interval at which images are encoded and transmitted. The image rate in ips (images per second) is displayed next to the text field.

Video resolution

Here you can select the desired resolution for the video image. The following resolutions are available:

–CIF

352 × 288/240 pixels

–4CIF/D1

704 × 576/480 pixels

Expert Settings

You can use the expert settings to adapt the I-frame quality and the P-frame quality to specific requirements, if necessary. The setting is based on the H.264 quantization parameter (QP).

I-frame quality

This setting allows you to adjust the image quality of the I-frames. The basic setting Auto automatically adjusts the quality to the settings for the P-frame video quality. Alternatively, you can use the slide control to set a value between 9 and 51. The value 9 represents the best image quality with, if necessary, a lower frame refresh rate depending on the settings for the maximum data rate. A value of 51 results in a very high refresh rate and lower image quality.
