4
In the Resolution list, select the required resolution for the video output.
5
In the Bitrate Type list, select Variable or Constant.
Constant bit rate mode (CBR) is generally safest. Although the image quality may vary,
the network load generated will remain fairly constant.
If constant picture quality is required and a varying network load will pose no problems,
choose Variable bit rate mode (VBR). Video streaming is generally smoother under VBR.
6
In the Video Quality list, select a video quality level.
The Video Quality list is available if the bit rate type is set to Variable.
Note that higher video quality levels require more bandwidth.
7
In the Frame Rate list, select a frame rate for the stream.
The frame rate determines the frequency at which the video stream is updated. It is
expressed in frames per second (fps). A higher frame rate is advantageous when there
is movement in the video stream, as it maintains the image quality throughout.
8
In the Max. Bitrate list, enter a value for the maximum bit rate to be allowed.
Higher values will give a higher video quality, but more bandwidth is required.
Note that the available values in this list can vary per camera model.
9
In the Video Encoding list, select the encoding mode - that is, the method used to
compress the video input signal.
Note that the available encoding modes (for example H.264, MPEG-4 and MJPEG) vary
per camera model and per stream type.
10
In the Profile list, select Basic Profile, Main Profile or High Profile.
These profiles are available in H.264 encoding mode.
11
In I Frame Interval, type the required value.
Range: 1~400. This setting determines the distance in frames between two I-frames.
12
In the SVC list, select ON, Auto or OFF.
Scalable Video Coding (SVC) is an extension of the H.264/AVC standard.
ON: Turns on the SVC function.
OFF: Turns off the SVC function.
Auto: The camera automatically extracts frames from the original video if the network
bandwidth is insufficient.
SVC is a video encoding technology. It extracts frames from the original video and sends
these frames to a video recorder (which also supports the SVC function) when the
network bandwidth is insufficient.

To configure audio streaming
1
In the Audio Encoding list, select the mode to be used.
G.722.1, G.711 ulaw, G.711alaw, G.726, MP2L2 and PCM are selectable. For MP2L2, the
sampling rate and audio stream bitrate are configurable. For PCM, the sampling rate can
be set.
2
In the Audio Input list, select the required input.
MicIn and LineIn are selectable for a connected microphone and intercom, respectively.
3
Drag the Input Volume slider to control the volume of the audio input.
4
In the Environmental Noise Filter list, select ON or OFF.
With this function turned on, the noise in the environment can be filtered to some
extent.
