SDK Service: SDK protocol is used.
Enhanced SDK Service: SDK over TLS protocol is used. Communication between the
device and the client software is secured by using TLS (Transport Layer Security)
protocol.
TLS (Transport Layer Security)
The device offers TLS 1.1 and TLS 1.2. Enable one or more protocol versions according
to your need.
Smooth Streaming
Purpose:
When the network is unstable or high quality of video is required, you can enable Smooth
Streaming function to view the live view smoothly via the client software or Web Browser.
Before You Start:
Add the device to your client software and select NPQ protocol in client software before
configuring the smooth streaming function.
Steps:
1. Enter the Smooth Streaming Settings interface.
Configuration > Network > Advanced Settings > Smooth Streaming
2. Check to enable the function.
3. Select the Stream Type.
Note:
Be sure the Bitrate Type is selected as Constant and the SVC is selected as OFF before enable
this function. Go to Configuration > Video/Audio > Video page to set the parameters.
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 and resolution will take the priority.
The upper limits of these two parameters 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. And in this mode the framerate will be adjusted to
Max. value automatically.
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. And in this mode the frame rate will be adjusted to
Max. value automatically.
Error Correction:
The resolution and bitrate stay the same as the set values in Video page. When the
bandwidth is sufficient, there is packet loss or bit error during transmission and these
situations will lead to the video data error or loss.
This mode is used to correct the data error during transmission to ensure the image quality.
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
