Xiaomi’s modern smartphones have become powerful multimedia centers capable of performing specialized diagnostic equipment. One such use case is the use of a video endoscope that allows you to look into hard-to-reach places of machinery, pipes or internal cavities of a car. Owners of Redmi, POCO and Xiaomi Mi devices often wonder how to turn their gadget into a night vision device or a technical inspector.
The setup process depends on the type of device you choose: wired (USB) or wireless (WiFi). In both cases, the MIUI or HyperOS operating system requires certain permissions and the correct sequence of actions to correctly transmit the video stream. Errors during the connection stage can lead to the camera not being identified or the image will be transmitted with a delay.
In this article, we will discuss in detail all the nuances of pairing, software selection and solving typical problems. It is critical to understand that not all Xiaomi models support video transmission through the Internet. USB-port OTG We'll look at how to test this feature and what to do if standard methods don't work.
Equipment preparation and OTG compatibility check
The first step before buying or connecting an endoscope is to check that your smartphone supports USB OTG (On-The-Go) function. Most current Xiaomi models, starting with the Redmi Note 4 series and later, as well as all flagship lines, have built-in support for this technology. However, in budget segments or very old models, the feature may be software-limited or physically absent.
You don't need a sophisticated tester to test, just connect to your smartphone via a conventional adapter. USB-If the file manager automatically opens the contents of the drive, then the port is in host mode and ready to receive the video signal. If there is no reaction, you may need to activate through an engineering menu or use a special activator application.
⚠️ Note: Use of cheap adapters OTG without shielding can cause interference in the video signal or even short circuit. Use only certified cables labeled Micro-USB or Type-C.
Also worth paying attention to the endoscope connector itself. Many budget models have a Micro-USB connector, whereas modern Xiaomi are equipped with a Type-C port. You may need a quality adapter that supports data transfer, not just charging. Cheap "charging only" cables will not transmit a video signal.
- 📱 Check the smartphone model in the specifications for support USB Host.
- 🔌 Test the port with the help of USB-Flips and any file manager.
- 🔋 Make sure your battery is above 20% as video is energy-intensive.
- 🧹 Clean the charging port of dust and pile, which can interfere with tight contact.
Choice of video surveillance software
Once you're physically connected, you're going to have to choose the software. Endoscopes don't work like standard webcams that you can turn on in a standard Camera app. They need a dedicated app that decodes the video stream from the chip inside the camera. There are a few popular solutions for Android smartphones, including Xiaomi.
The most universal application is considered USB Camera (Developer ShenZhen Yushengchang) supports a wide range of chipsets and allows you to adjust resolution, brightness and contrast. WiFi endoscopes often use applications Wi-Fi View, MaxSee or HomeKit, which come bundled with the device on the device. QR-Installing third-party software from Google Play often gives a more stable result than using disk versions.
When it first runs, it'll ask for a number of critical permissions. MIUI The security system can aggressively block access to the camera or microphone. USB-devices, storage and, in some cases, allow display on top of other windows. Without these settings, the video stream will not be displayed.
💡
If the application does not see the camera, try the developer settings (item "Debugging by" USB") switch off USB, Remember to return it after use.
Some users experience a black screen, often due to codec conflict, and in the app settings, try changing the decoding format from Hardware to Software or vice versa, and check whether the antivirus or Xiaomi’s built-in protector blocks the app from accessing the network and ports.
Instructions: Connecting wired USB-endoscope
The process of connecting a wired camera requires a strict sequence of actions. Violation of the order of on can lead to the fact that the smartphone does not recognize the device. First, make sure that the application is already installed and has all the necessary permissions, but is closed for now.
Connect the adapter. OTG Then insert the endoscope plug into the adapter, at which point the LED on the camera (if any) should light up, signaling the power supply. Only then launch the video surveillance app. The system should automatically detect the new one. USB-device.
