SWZ-HD

The Camera has two fundamental modes of operation:

•

Constant Bitrate. This will output a constant bit rate IP video stream, as set in the Bit rate field.

•

Constant Quality. In this mode the bit rate is varied in a effort to maintain a constant quality.

The target quality is set using a number between 0 to 51, the lower the number the higher

the quality, this is set in the quality field. Amendments to this value are only allowed when the

constant quality mode is enabled� In this mode the 'ceiling' bit rate is controlled by the value set

in the Bitrate field, the encoder will attempt to limit the maximum bit rate to this value.

H.264 Resolution

The maximum resolution is 1920x1080, users can select lower resolutions if there is restricted

bandwidth available�

H.264 FPS (frames Per Second)

The maximum frame rate is 30fps, users may choose to select lower frame rates, thereby reducing

the bandwidth required�

H.264 IDR Frame changes to the I frame interval balances the stream's quality against latency, the

lower the number the lower the latency� Lower latency however can incur picture degradation due

to the effect of limiting the decoder buffer.

Video Flip can be useful when the camera is installed upside down�

Video Reverse can be useful when viewing the image via a mirror�

Video Flicker can be adjusted to suit the local mains frequency when the camera is used under

artificial lighting conditions.

Night Video Mode will increase the sensitivity of the camera under low light conditions�

LED Control for cameras with LED illuminators included. Select either Off or Auto mode for the LED

type, the LED type will become active as determined by the ambient light level�
