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
Select either Off or Auto mode for the LED type, the LED type will become active as
determined by the ambient light level.
Users should press the

Video Frame Preview
It is possible to view a single still image from the camera via a web browser using the following URL
format:

The above URL is applicable when the camera is set to its default IP address.
