Turning Xiaomi into a webcam: the complete guide

In the era of remote work and constant video hangouts, image quality has become a critical factor in professional communication. Built-in cameras in laptops are often inferior in resolution and sensitivity to even budget smartphones, which creates an obvious imbalance in the visual component of your calls. Fortunately, modern technology makes it easy to use your Xiaomi’s powerful sensor as a high-quality source of video for your computer.

There are several effective ways to stream, each with its own advantages depending on your goals: You can use both a wired connection for maximum stability and a wireless connection for mobility, although you can use a wired connection for maximum stability. USB-Connectivity remains the preferred option for high-resolution work, and in this article we will discuss in detail the algorithms of actions that will help you get a picture of studio quality without unnecessary costs.

Before you start setting up, it is worth noting that the process of turning a smartphone into a peripheral device requires the installation of special software. This can be both built-in functionality of the system and third-party client applications that act as drivers. Proper preparation of hardware and software is the key to successful synchronization, so do not miss the preparatory stages.

Many users underestimate the potential of their gadgets by continuing to use a blurry image of embedded modules. However, knowing how to connect Xiaomi to a computer as a web camera correctly, you can significantly improve the level of your presentations, streams or communication with loved ones. Let's consider the necessary tools and steps to implement this task.

Selection of broadcasting software

The first step towards a quality image is to choose the right application that will stream video from the smartphone sensor to the monitor screen. The market offers many solutions, but for Xiaomi devices, several proven options have proven themselves best, the main leaders in this niche are DroidCam, Iriun Webcam and Camo, each of which has its own features of the interface and functionality.

When choosing software, it is important to pay attention to resolution support and the availability of watermarks in free versions. Some programs limit quality to 480p or 720p without buying a license, while others allow you to use the full potential of your phone’s matrix for free.

Here are the main characteristics of popular solutions that will help you decide on the choice:

• 📱 DroidCam is a classic solution with support for sound and video streaming, works through Wi-Fi and USB, lightweight interface.
• 🎥 Iriun Webcam supports resolution up to 4K in the paid version, differs by minimal delay and ease of setting up drivers.
• 🎨 Camo – offers advanced color correction and focus management tools, perfect for professional streamers.
• 🔌 EpocCam, a product from Elgato, often used in conjunction with the video capture ecosystem, provides a stable connection.

Installation of the selected application requires care, as the computer needs to install not only the client part, but also special drivers. Without properly installed virtual camera drivers, the operating system will not see your phone as a video source. Usually, the installer offers to download all the necessary components automatically, but in some cases, manual activation may be required.

Connection through USB-cable: maximum stability

Using a wired connection is the most reliable way to organize video communication, since it eliminates the delays typical of wireless networks. To implement this method, you will need a quality USB cable that can transmit data, not only charge the battery. Cheap “charging only” cables will not work, since they do not physically have internal contacts to transmit information.

Once you connect the cable to your computer port and smartphone, you need to activate the USB debugging mode in the developer menu. This is a hidden partition in the MIUI system that allows the computer to gain advanced access rights to the device. If you haven't already enabled this mode, go to Settings → About phone and quickly click on the build number seven times, after which the "Developers" item appears in the menu.

Inside the developer menu, find the Debugging item USB And you can activate it with a slider, and when you first connect to your PC, you'll see a confirmation request on your smartphone screen. RSA-If you don't do this, you'll be able to press "Allow." Without this step, the computer won't be able to connect to the phone, and the camera program will show a black screen or a connection error.

The next step is to choose the mode of operation. USB Unlike file transfers, the camera often requires a mode to operate. USB-Some programs, such as DroidCam, may operate in file transfer mode, but audio transmission often requires modem mode or network emulation.

⚠️ Note: When activating debugging by USB Your smartphone becomes more vulnerable to external connections. Do not leave this mode on permanently if you are in public places with charging stations, as this can lead to unauthorized access to data.

Set up a wireless connection over Wi-Fi

The wireless method of connection is convenient because it eliminates unnecessary wires and allows you to place the smartphone anywhere in the room. However, for stable operation, both the computer and Xiaomi must be on the same local network. Using guest Wi-Fi or different frequency bands (2.4 GHz and 5 GHz with client isolation) can lead to the fact that the devices simply do not “see” each other.

To get started, run the camera app on your smartphone; the screen usually shows up IP-The address and port through which the broadcast is transmitted must be entered into the client program on the computer. If the automatic search does not work, manual entry of addresses, such as 192.168.1.5:4747, often solves the connection problem.

The quality of the video stream over Wi-Fi depends on the speed of your network and signal level. If you plan to broadcast video in high resolution, make sure that you use Wi-Fi 5 standard (802.11ac) or later. In congested air in apartment buildings, short-term communication breaks or compression artifacts in the image are possible.

There is also the possibility of creating an access point directly on a smartphone, but in this case the computer will lose access to the Internet if it does not have a second network adapter, which is only suitable for local data transfer without access to the network, which is not acceptable for video calls, so it is preferable to use a shared router.

Comparison of Connection Methods and Their Characteristics

The choice between wired and wireless often depends on the specific operating conditions and image quality requirements, and to make it easier for you to determine, we have prepared a comparison table that shows the key differences between these methods, which will help you weigh the pros and cons before you start setting up.

As you can see from the table, USB-The cable is a great advantage in all the technical aspects of quality and stability of data transmission, but if you have to move around the room often or do demonstrations standing up, wireless connection is a more comfortable choice. Bluetooth is not used in this context because of the low bandwidth, sufficient only for audio or control commands.

It is also worth considering the power consumption: when working through USB, the smartphone charges simultaneously, which allows you to use it for hours without interruption. When working on Wi-Fi, the battery discharges much faster due to the operation of the radio module and the processor, so it is recommended to keep the device on a stand with a connected charger.

Resolving common problems and errors

Even with strict follow-up, users may face technical difficulties such as a black screen, lack of sound or connection breaks. One of the common causes of problems on Xiaomi devices is the aggressive MIUI energy saving system, which can kill the background processes of the camera application. To avoid this, you need to manually set up autostart and remove battery restrictions for the software used.

To set up, go to Settings → Apps → All apps, find your app (like DroidCam) and select Battery. Set No Limits mode. Also remember to allow auto-start in the appropriate menu, otherwise after restarting your computer or phone, the stream will not start automatically.

If your computer doesn’t see the camera in the device list in Skype or Zoom, check to see if the device is the default in the system privacy settings. In Windows 10/11, go to Settings → Privacy → Camera and make sure that access for classic applications is allowed. Sometimes antivirus programs block virtual drivers, considering them suspicious.

💡

If the audio is late or not working at all, try changing the audio codec in the app settings on your phone. Often switching from the default codec to AAC or Opus solves the problem of desynchronizing audio and video.

⚠️ Note: If you have driver errors, do not delete Android system files. Try reinstalling the client part on your PC by running the installer on behalf of the administrator, and reconnecting the cable to another. USB-port, preferably directly to the motherboard, and not through USB-hub.

Additional features and operating advice

Using a smartphone as a webcam gives you access to features not available to regular webcams, such as macro photography, optical zoom, and using a second camera. You can physically move your phone to show the details of an item close-up, which is especially useful for product reviews or document demonstrations. This turns your Xiaomi into a full-fledged document camera.

To secure the device in a comfortable position, it is recommended to use a flexible tripod or suction holder, which will free your hands and lock the camera at the optimal height - at eye level, which is the standard for video communication. Avoid shooting from the bottom up, as this visually distorts the proportions of the face.

Remember the lighting: even the best camera can't make a good picture in the dark, use natural light from the window, or buy an inexpensive ring light, combined with a good smartphone lens, it will give you a picture that looks professional and pleasant to the interlocutor.
