For detailed configuration, refer to Section 0 Smooth Streaming
Purpose:
This function is used to view the live view smoothly via the client
software or Web Browser when the network is unstable or high
quality of video is required.
Notes:
Supported services vary according to camera models.
Before you start:
Add the device to your client software and enable the NPQ protocol
for live view via the client.
Steps:
1. Enter the Smooth Streaming interface:
Configuration > Network > Advanced Settings > Smooth
Streaming
2. Select the Stream Type.
3. Check Enable Smooth Streaming.
4. Select the mode of smooth streaming. There are three modes
selectable: Auto, Resolution Priority, and Error Correction.
 Auto: The resolution and bitrate will be adjusted
automatically, the upper limits of which will not exceed the
values you set on Video page. Go to Configuration >
Video/Audio > Video page, set the Resolution and Max.
Bitrate before you enable smooth streaming function.
 Resolution Priority: The resolution stays the same as the
set value in Video page, and the bitrate will be adjusted
automatically. Go to Configuration > Video/Audio > Video
page, set the Max. Bitrate before you enable smooth
streaming function.
 Error Correction: The resolution and bitrate stay the same
as the set values in Video page. This mode is used to
correct the data error during transmission. You can
configure the error correction proportion within range of
0-100. When the proportion is 0, the data error will be
corrected by data retransmission. When the proportion is
higher than 0, the error data will be recovered via
redundant data that is added to the stream. The higher the
value is, the more redundant date will be generated, and
the larger bandwidth is required. When the proportion is
100, the redundant data will be as large as the original
data.
Note: Be sure the bandwidth is sufficient in Error
Correction mode.
