The IoT Platform provides default feature definitions for video products. For this quick start, use the default properties.
Click Next: Device Debugging to add a test device.
Select the module information.
For this quick start, you can select any module information. For production devices, select the information that matches your module.
Click Add Test Device. The Add Test Device dialog box appears.
After you add a test device, you can use the free device certificate provided by the platform to debug the device. Each product supports up to 50 free test devices. The certificates for test devices are for debugging only and cannot be used for mass production.
Click OK. The device certificate for the test device appears in the dialog box.

Run the Link Visual demo
The IoT Platform provides a Link Visual demo for Linux. Follow these steps to run the demo and use a virtual camera to try the Link Visual service.
Download the Link Visual demo.
The IoT Platform provides two types of Link Visual demos. Select one based on your development environment.
Link Visual demo for Ubuntu
This demo is compiled on an x86 64-bit Ubuntu 16.04 system. It has not been tested on other Linux versions. To avoid compatibility issues, we recommend that you install the same Ubuntu version. Click to download the Link Visual demo for Ubuntu
Link Visual demo for Docker
The Docker image provides better cross-platform capabilities. You can install Docker on operating systems such as Windows, macOS, and Linux, and run the demo in Docker. Click to download the Link Visual demo for Docker

your_devicesecret with your device certificate information. For more information, see
Test device certificate.
Check the results of the Link Visual demo.
In the app, trigger features such as live streaming and video-on-demand to watch the playback.
When a feature is triggered in the app, view the real-time device logs in Docker or Ubuntu where the Link Visual demo is running.
After the virtual device is attached, you can try the features of Link Visual.
From the device list in the public app (Cloud Intelligence), select the camera device. You will see the following interfaces: live streaming, settings, gallery, and local video playback.
The camera product in the current public app includes the following features.
Feature
Description
Camera settings
Includes settings for day/night mode, video image flip, alarm switch, motion detection sensitivity, alarm frequency, alarm period, storage card status, capacity display, and storage card formatting. The alarm switch controls device alarms. When triggered, the device uploads an alarm photo to the cloud for viewing in the gallery. Formatting the storage card deletes all files on it.
Live stream resolution switching
Switch the resolution based on the types your device supports.
Live stream sound switch
This switch only controls the volume of the live stream on your phone. It does not affect the sound captured by the camera.
Live stream screen recording
Record a segment of the current live stream. You can view the resulting file in your phone's photo album.
Live stream screenshot
Take a screenshot of the current live stream. You can view the resulting file in your phone's photo album.
Voice intercom
Use this feature to have a voice chat with people near the camera.
Camera rotation control
Use the control pad on the live stream page to rotate the camera up, down, left, and right to see the desired view.
Gallery
Displays alarm pictures generated by device alarms. The reporting switch, sensitivity, frequency, and time period are configured in the "Alarm Settings" section.
Card recording
Displays historical recordings saved on the camera's storage card for a certain period. You can view card recordings from any time period.
Cloud recording
View recordings that are generated by device alarms and uploaded to the cloud.
