Equipment and training required
Before you start setting up, you need to make sure you have the right set of equipment. The standard cable that comes with the camera is often just for charging and doesn't support data transfer at the right speed. You'll need a quality micro-USB cable with data support.
It is also critical to have a computer with a good one. USB-It is desirable to use ports. USB 3.0 (blue) as they provide more bandwidth and stable power. USB 2.0 may have problems with high-resolution video stream transmission.
☑️ Checking connection readiness
Remember to update the firmware of the camera itself via the mobile app before connecting to the PC. In older versions of the software, the webcam mode may not work correctly or at all.
Setup of the camera to work in webcam mode
The first step is to properly configure the settings inside the camera itself. The Xiaomi Yi 4K interface is quite simple, but hidden menus can be confusing for the beginner. You need to find the partition responsible for connecting to the PC and activate the appropriate mode.
Go to the settings and find the USB Connection. It can be the default charging mode or MTP. You need to switch it to UVC or Webcam. It's this setting that makes the camera transmit a video signal, not just charge.
⚠️ Note: If after switching the mode UVC The camera screen goes out, that's OK. The camera goes into video standby from the computer.
Next, you need to choose resolution and frame rate. For video, the best option is 1080p at 30 or 60 frames per second. 4K mode can be redundant for Zoom or Skype and will put extra strain on the computer processor, causing delays.

Connecting to a computer and installing drivers
Modern operating systems such as Windows 10/11 and macOS usually automatically recognize the Xiaomi Yi 4K as a video capture device. UVC drivers are built into the core of the system, so manual installation is often not required.
If the computer makes a device connection sound after you connect, but the camera doesn't appear on the list of available devices, check the Device Manager. The camera may be identified as an unknown device. In this case, try updating the driver by selecting the standard USB Video Device driver from the list.
| Parameter | Optimal value | The alternative |
|---|---|---|
| Permission | 1920x1080 | 1280x720 |
| Frequency of personnel | 30 FPS | 60 FPS |
| Format | MJPEG | YUY2 |
| White balance | Automobile | Filament lamp |
For Linux users, the system usually sees the camera right away, but access rights may be required. You may need to add a user to a video group or create a udev rule.
💡
Use an active-powered USB extender if the camera is periodically shut down, which will solve the problem of the lack of current from the motherboard port.
Use of OBS Studio and Zoom
Once the device is successfully connected to the system, you need to configure it in the target application. In OBS Studio, add a new source "Video Capture Device" and select Xiaomi Yi 4K. If the image is black and white or missing, change the type of video format in the source properties.

Pay attention to the system load. High bitrate streaming can be loading on the processor. If you notice a drop in FPS in a game or lag in the system, try lowering the resolution in the camera or streaming app settings.
Solving problems and troubleshooting
One of the most common problems is that the camera is spontaneously turned off while running, often due to USB power saving settings in Windows, which may attempt to turn off the port to save power by interrupting the video stream.
To fix this, open Device Manager, find root USB-Hub, go to properties, and on the Power Control tab, uncheck the box on "Allow this device to be turned off." This stabilizes the power.
⚠️ Attention: During prolonged operation in the mode of the webcam, the device body can be very hot. This is a normal situation, but it is recommended to ensure good ventilation around the camera.
If the image twitches or has artifacts, replace USB-Cheap cables often can't withstand long data transfers, resulting in packet loss and image distortion. Use screened cables no longer than 1.5 meters long.

90% of the stability depends on quality USB-Cable and energy saving settings of the operating system.
Additional features and life hacks
Using the Xiaomi Yi 4K as a webcam, you get access to its wide viewing angle. This allows you to capture not only the face, but also part of the interior or board if you are doing presentations. To narrow the angle, you can use digital zoom in OBS without losing smoothness.
Some enthusiasts use third-party utilities to superimpose color correction filters directly onto the video stream before sending it to stream software, which allows you to tailor the picture to any interior, making it more professional and pleasant for the viewer.
Also worth remembering is focal length. The camera has a fixed focus, optimized for shooting from arm's length and beyond. If you put the camera too close to your face, the focus can float, so keep a distance of at least 50-70 cm.
