Modern security systems require constant attention to software, and Xiaomi DVRs are no exception. Regular firmware updates not only provide new features, but also close critical vulnerabilities in the security system of the device. Many users ignore notifications of new versions of software, relying on the stable operation of the current configuration, but this can lead to reduced recording quality or problems with connecting to cloud services.
The upgrade process has become much easier with the development of the Mi Home ecosystem, but still requires certain technical nuances. Connection stability and battery level are crucial to the successful completion of the procedure. In this article, we will discuss in detail all stages of software modernization, consider manual installation methods and answer frequent questions that arise from owners of smart cameras.
Why you need to update the firmware of the video recorder
Developers are constantly working to improve video compression algorithms and connection stabilization. Optimizing codecs saves memory card space without losing visual quality. New versions often contain patches that fix bugs that could cause spontaneous reboots or loss of record archives at a critical moment.
Data security is another big argument for timely updates: Smart devices are part of the Internet of Things, and protecting video channels must be as up-to-date as possible. The updated firmware ensures that your video recordings are not made available to unauthorized people due to vulnerabilities in old encryption protocols.
⚠️ Warning: Installing unverified firmware versions from third-party sources may cause permanent damage to the device. Use only official update channels through the Mi Home app or manufacturer's website.
Functional improvements often affect how AI works in the camera. Facial recognition algorithms, motion detection, and sound anomalies are more accurate with each version. If your DVR starts to get worse at night or falsely respond to shadows, it's likely that the problem is solved by installing the actual software.
Preparation of the device for the update procedure
Before you start any manipulation of the system software, you need to carry out a number of preparatory actions: first of all, make sure that the DVR is connected to a stable Wi-Fi network. Interrupting the download of the firmware file can lead to a software failure, so the quality of the signal is paramount.
The second important parameter is the battery level: if the device is powered by an integrated battery, its charge should be at least 50-60%. For models that are exclusively powered by the mains, it is recommended to use the original power supply and cable to avoid surges of voltage during the process.
☑️ Readiness for renewal
Also worth checking is the status of the memory card. The microSD file system should be fine, as temporary update files can be written to the buffer. If the memory card has errors, the system may refuse to start the installation procedure.
Automatic updates via Mi Home app
The most common and safe way to upgrade is to use the official Mi Home app, which will notify the user of the availability of a new version if the automatic updates are not disabled in the settings, manually open the application, select your DVR from the list of devices and go to the settings menu.
In the upper right corner of the screen, there is usually a three-dot button or a gear that opens the device control menu. Find Version Update or Update Check. If the new version is available, a corresponding notification will appear describing the changes and download button.
- 📱 Open the Mi Home app and make sure your phone is connected to the same Wi-Fi network as the camera.
- 🔍 Go to the device card and click on the settings icon in the upper right corner.
- ⬇️ Select the update checkpoint and wait for the file to load.
- ✅ Confirm installation and do not turn off the device until a success message appears.
During installation, the device may reboot several times, and the status indicator may flash yellow or blue, which is a routine behavior that indicates the writing of new system files, interruption of the process at this stage is highly undesirable, as it may require recovery through the service center.
💡
Automatic updates through the application are the most reliable method, minimizing the risk of user errors and guaranteeing the installation of a compatible version of the software.
Manual installation of firmware through a memory card
In cases where the automatic update does not start or the device does not have access to the Internet, a manual method is used. This will require a computer, a card reader and a microSD memory card itself. The firmware file should be downloaded from the official support site or specialized forums, making sure that the model of your DVR is exactly matched.
A downloaded file usually has a.bin extension and a specific name, such as a file, mi_camera_fw.bin. This file needs to be placed in the root memory card. FAT32, Otherwise, the device will not be able to read the installation file.
| Parameter | Requirement | Note |
|---|---|---|
| File system | FAT32 | Necessary for compatibility |
| File name | mi_camera_fw.bin | No change to expansion |
| Location. | Root folder | Not in DCIM or MIOT folders. |
| Volume of map | Up to 32GB | Recommended for compatibility |
After you write the file, insert the memory card into the DVR turned off and power it. The device automatically detects the update file and starts the installation process, which it signals with an audible message or a change in the color of the indicator. Once completed, the camera will restart, and the firmware file can be deleted.
What to do if the update has not started?
Common Errors and How to Resolve Them
The upgrade process is not always smooth and users may encounter various errors, often due to an unstable Internet connection or a lockdown of the update servers by the provider. DNS-servers in the router or using the mobile access point for initial loading.
Another common situation is that the current version is newer than the one available in the region, which means that you're trying to install global firmware on the Chinese version of the device or vice versa, and the regional ownership of the device is strictly controlled, and mixing software versions is not allowed.
- 🌐 Network error: Check date and time settings on router, wrong time knocks down security certificates.
- 📉 Low charge: Connect the device to a powerful power supply, USB-The computer port may not provide enough power.
- 💾 Card error: Format the memory card in the camera app before writing the firmware file.
If the device is stuck in the process of updating and the indicator is on a straight light for more than 15 minutes, forced reboot. To do this, you need to press the reset button and, holding it, connect the power. Hold the button for 5-10 seconds until the sound signal appears.
⚠️ Warning: Do not try to reflash the device if it is warranty and stable. Interference with the code can be grounds for denial of warranty service.
Settings after updating and checking the functionality
After successful installation of the new firmware version, it is recommended to reset the camera settings to factory ones. This is not necessary, but desirable, since old configuration files may conflict with new algorithms of the system.
Check the basic features of the device: real-time video quality, nighttime performance, motion sensor sensitivity and sound recording. Make sure the time stamps are displayed correctly, as time is often reset to default after resetting.
💡
After updating and resetting the settings, reset the recording schedule and motion detector sensitivity, as these parameters could return to factory values.
It’s also worth checking your cloud services if you’re using a Xiaomi Cloud subscription. New versions of the software sometimes change the login protocols, which requires you to log in again, and make sure the record archive is saved correctly and available for viewing.
