Conduct 3D Positioning
3D positioning relocates the selected area to the image center.
Steps
1. Click to enable the function.
2. Select a target area in live image.
•Left click on a point on live image: the point is relocated to the center of the live image with no
zooming in or out effect.
•Hold and drag the mouse to a lower right position to frame an area on the live. The framed area is
zoomed in and relocated to the center of the live image.
•Hold and drag the mouse to an upper left position to frame an area on the live. The framed area is
zoomed out and relocated to the center of the live image.
3. Click the button again to turn off the function.
Set Transmission Parameters
The live view image may be displayed abnormally according to the network conditions. In different
network environments, you can adjust the transmission parameters to solve the problem.
Steps
1. Go to Configuration →Local.
2. Set the transmission parameters as required.
•Protocol
-TCP
TCP ensures complete delivery of streaming data and better video quality, yet the real-time
transmission will be affected. It is suitable for a stable network environment.
-UDP
UDP is suitable for an unstable network environment that does not demand high video fluency.
-MULTICAST
Multicast is suitable for situations where there are multiple clients. You should set the
multicast address for them before selection.
For detailed information about multicast, refer to Multicast.
-HTTP

HTTP is suitable for situations in which a third-party needs to get the stream from the device.
•Play Performance
-Shortest Delay
The device takes the real-time video image as the priority over the video fluency.
-Balanced
The device ensures both the real-time video image and the fluency.
-Fluent
The device takes the video fluency as the priority over real-time. In a poor network environment,
the device cannot ensures video fluency even if the fluency is enabled.
-Custom
You can set the frame rate manually. In a poor network environment, you can reduce the frame
rate to get a fluent live view. But the rule information may not display.
3. Click OK.
Set Smooth Streaming
This function tackles latency and network congestion caused by unstable network condition, and keeps
the live view stream on the Web browser or the client software smooth.
Before You Start
Add the device to your client software and select NPQ protocol in client software before configuring the
smooth streaming function.
Be sure that the Bitrate Type is selected as Constant and SVC is selected as OFF before enabling the
function. Go to Configuration →Video/Audio →Video to set the parameters.
Steps
1. Go to the settings page: Configuration →Network →Advanced Settings →Smooth Streaming.
2. Check Enable Smooth Streaming.
3. Select the mode for smooth streaming.
•Auto: The resolution and bitrate are adjusted automatically, with resolution taking priority. The
upper limits of these two parameters will not exceed the values you set on the Video page. Go to
Configuration →Video/Audio →Video, set the Resolution and Max. Bitrate before you enable the
smooth streaming function. In this mode, the frame rate will adjust to the maximum value
automatically.
•Resolution Priority: The resolution stays the same as the set value on the Video page, and the
bitrate will be adjusted automatically. Go to Configuration →Video/Audio →Video, set the Max.
Bitrate before you enable smooth streaming function. In this mode, the framerate will be adjusted to
the maximum value automatically.

•Error Correction: The resolution and bitrate stay the same as the set values on Video page. The
mode is used to correct the data error during transmission to ensure the image quality. You can set
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 corrected via redundant data that is added to the
stream and data retransmission. The higher the value, the more redundant date will be generated,
the more data error would be corrected, but a larger bandwidth would be required. When the
proportion is 100, the redundant data will be as large as the original data, and twice the bandwidth
is required.
Be sure the bandwidth is sufficient in the Error Correction mode.
4. Save the settings.

Chapter 4 Video and Audio
This part introduces the configuration of video and audio related parameters.
Video Settings
This section introduces video parameter settings such as stream type, video encoding, and resolution.
1. Go to setting page: Configuration →Video/Audio →Video.
Stream Type
For devices that support more than one stream, you can specify parameters for each stream type.
•Main Stream: This stream stands for the best stream performance the device supports. It usually offers
the best resolution and frame rate the device can do. But high resolution and frame rate usually
means larger storage space and higher bandwidth requirements in transmission.
•Sub Stream: This stream usually offers comparatively low resolution options, which consumes less
bandwidth and storage space.
•Other Streams: Steams other than the main stream and sub stream may also be offered for customized
usage.
•Set Custom Video:You can set up additional video streams if required. For custom video streams, you
can preview them, but cannot record or play them back.
Steps
The function is supported only by certain camera models.
After restoring the device (not restore to default settings), quantity of custom video
streams and their names are kept, but the related parameters are restored.
1. Click to add a stream.
2. Change the stream name as needed.
Up to 32 letters and symbols (except &, <, >, ', or ") are allowed for the stream name.
3. Customize the stream parameters (resolution, frame rate, max. bitrate, video encoding).
4. Optional: Add stream description as needed.
5. Optional: If a custom stream is not needed, click to delete it.
6. Click Save.
Video Type
Select the content (video and audio) that should be contained in the stream.
