Encoding interval:

This setting determines the frame encoding interval. The value 1 means each

image is encoded. The value 2 means that only every other image is encoded,

etc. The lower the available transmission bandwidth, the higher this value should

be set in order to maintain high-quality images despite the bandwidth.

Video resolution:

Select the desired resolution for the MPEG-4 video image. The following options

are available:

] QCIF 176 × 144 pixels

] CIF 352 × 288 pixels

] 2CIF 704 × 288 pixels

] D1/4CIF 704 × 576/480 pixels

] Custom 352 × 576/480 pixels, adjustable (default setting is 1/2 D1)

Field mode:

This parameter determines the video signals being Interlaced or Progressive.

Reset of profile:

Click the Default button to reset the profile to its factory presets.

Audio stream

In addition to video data, the unit can also send and receive audio signals. The

transmission of audio takes place at the same time as that of the video data in a

separate data stream. Thus it increases the data traffic. The audio data is coded

according to G.711 compression standard and requires an additional bandwidth

of about 80 kBit/s per direction.
