The era of video conferencing and remote work has forced many users to reconsider the quality of their webcams. Standard devices built into laptops or budget models from peripheral brands often give out blurry images with poor color reproduction. At the same time, millions of people are dusting old Xiaomi Yi action cameras, which are technically able to shoot images much better than any typical webcam. Turning a compact gadget into a full-fledged video source is not only a budget saving, but also a significant upgrade of the visual quality of streams or calls.
Using an action camera as a webcam requires understanding a few nuances of connectivity. You don't need to be an engineer to set up streaming, but you have to spend time choosing the right software and connection method. There are two main methods: wired (via USB) and wireless (via Wi-Fi router or access point), each of which has its own advantages, which we will discuss in detail in this guide.
Before you start manipulating cables, it is important to make sure that your device is charged and ready to go. The camera firmware should be up to date, as older versions of the software may not work properly with new drivers or broadcast applications. We will review all the preparation steps so that you can immediately get a stable video stream without unnecessary technical problems.
Equipment and software required
To implement the project, you will need the Xiaomi Yi camera itself (preferably the first or second version, including 4K models) and a computer running Windows, macOS or Linux. The key element is a cable. For wired connection, you need a quality Micro-USB cable with data transfer support, not just charging. Cheap cables from powerbanks often do not have internal contacts to transmit the signal, which will lead to a lack of response of the device when connected.
As for the software, the native functionality of the camera does not allow you to simply “enable webcam mode” with a single button. You will need third-party software that will capture the video stream and broadcast it to the system as a virtual device. The most popular and proven solution is the Yi Camera program. USB (or its forks, as well as universal utilities such as OBS Studios that can capture network streams may also need libusb drivers to work properly. USB-protocol at the operating system level.

☑️ Checking connection readiness
Method of wired connection via USB
Wired connection is considered the most stable option, providing minimal latency. This is critical if you plan to use the camera for live communication, where desynchronization of sound and video is not allowed. First, connect the camera to the computer with a cable. At this point, the mode selection menu may appear on the screen of the gadget. You need to choose the option USB WebCam or UVC (USB Video Class), if this option is available in your version of the firmware.
However, standard firmware Xiaomi Yi often does not have built-in UVC. In this case, the system does not recognize the camera as a web device automatically. You will need to run a specialized utility that will "wake up" the camera in the desired mode. After running the program on the computer, the camera should go to standby mode. When a successful connection, the indicator on the device body usually changes color or starts flashing in a certain way, signaling the transfer of data.
If the connection is established, a new device should appear in Windows Device Manager or macOS camera list, which can be called Yi Camera or USB Video Device. Now you can choose this camera from Skype, Zoom or Discord. Picture quality in this mode is usually limited to 640x480 or 1280x720 due to USB 2.0 bandwidth and driver limitations, but stability is more important than maximum resolution.
What to do if the computer can’t see the camera?
Set up wireless broadcasting via Wi-Fi
The wireless method allows Xiaomi Yi to be used as a webcam from a distance, which gives more freedom in the frame, for this camera and computer must be on the same Wi-Fi network. First, turn on the camera and wait for the connection to your router (Wi-Fi indicator should burn or blink in the set mode). IP-The camera address that is usually displayed on the device screen or in the smartphone app when connected via Wi-Fi Direct.
The computer then uses a translator program, for example, OBS Studio or specialized script that accepts RTSP-The flow address is usually the form rtsp://192.168.1.XX:8554/live. And if you type this address into a media source, you get a picture from the camera, and the advantage of this is that you can use high resolution, up to Full. HD even 4K (It depends on the power of the router, but here appears the main enemy - delay.
Wi-Fi latency can be between 0.5 and 3 seconds, which is acceptable for streaming gameplay where you comment on your actions, but it's totally unacceptable for live dialogue, because you'll be reacting to someone's words late, and it also puts the battery down much faster.
💡
To reduce latency when connecting to Wi-Fi, use a 5GHz router and place your camera as close to the access point as possible. Avoid using older 802.11n routers.
Comparison of Connection Methods and Their Characteristics
The choice between cable and wireless is often a decisive factor in the quality of the final image. The wired connection ensures that there are no compression artifacts that are often found in airborne transmission, especially if the network is loaded with other devices. However, cable limits mobility. Wireless connection gives freedom, but requires ideal network conditions.
The table below provides a detailed comparison of the characteristics of both methods so that you can choose the best use case for your tasks.
| Characteristics | USB Connection | Wi-Fi connection |
|---|---|---|
| Signal stability | Tall. | Medium (depending on router) |
| Delay (Latency) | Minimum (< 0.1 sec) | High (0.5 - 3 sec) |
| Maximum authorization | Up to 720p (often) | Up to 4K (theoretically) |
| Energy consumption | USB power | Fast battery discharge |
| Mobility | Limited by cable length | Tall. |
It should be noted that when you work in the mode of the webcam, the camera can overheat. Action cameras do not have active cooling (fans), so when you record or broadcast continuously, the body heats up. In wireless mode, heating is faster due to the active operation of the Wi-Fi module.
💡
For professional streams and important hangouts, always choose USB-Connection for stability, even if you have to sacrifice some of the permission.
Use in popular video conferencing applications
Once the camera is set up and broadcasts the image, you need to integrate it into the programs you use. In Zoom, Skype or Google Meet, you need to go to the video settings and in the Camera field, select the device that matches your setting (for example, OBS Virtual Camera or Yi USB Camera). If you use OBS to create a complex scene with overlays, then the OBS virtual camera is selected in the communication applications.
The microphone built into Xiaomi Yi is far from your mouth when using the camera as a webcam, so the sound will be deaf and echoing. It is recommended to completely disable the camera microphone in the system settings and use a separate USB-A microphone or headset that drastically improves your speech legibility.
For streamers using OBS Studio, the Xiaomi Yi camera offers an interesting opportunity: With its wide viewing angle (about 150 degrees), it captures not only the face, but also part of the room or workplace, which can be used to create a picture-in-the-picture effect or to show your hands if you're doing gadget reviews or drawing.
Solving common problems and errors
Users often face a number of typical problems during the setup process, one of the most common being a black screen instead of an image, which could mean that the camera is busy with a different process or has not switched to broadcast mode. Try turning off the camera completely, disconnect the cable, turn the camera back on, and then plug in the USB.
Another problem is intermittent video or "squares" in the image, which is a sign of a lack of bandwidth (with Wi-Fi) or a weak channel. USB-Try to lower the bitrate in the translation program settings or reduce the resolution. Also make sure that the computer does not run heavy background processes that consume the CPU resources.
- 🔄 Camera not turned on: Check battery charge and serviceability of charger.
- 📉 Low. FPS: Close the extra browser tabs and reduce the flow resolution.
- 🔇 No sound: Check the microphone privacy settings in Windows/macOS.
⚠️ Warning: Do not leave the camera connected to overnight charging in active mode unattended. Lithium-ion batteries can swell when overheated.
