Video surveillance users often face the need to transfer footage to a big screen or archived hard drive. Xiaomi ecosystem owners are no exception, as their devices are popular for their value for money. However, the standard interface of the Mi Home mobile application is not always convenient for working with large amounts of data, and a direct connection to a PC may not be obvious.
There are several proven methods of video retrieval, each with its own characteristics and network infrastructure requirements. The choice of the specific method depends on the model of your device, the availability of a memory card and the firmware version. In this article, we will discuss in detail the technical nuances of each option so that you can choose the most effective for your situation.
It's worth noting that cloud storage, while convenient for remote access, is rarely suitable for mass uploading of archives due to speed limits and paid tariffs. Local methods of transferring data over a local network or direct access to the file system provide maximum speed, this is especially true when working with 1080p or 2K resolutions, where files weigh a significant amount of gigabytes.
Direct connection via memory card
The easiest and most reliable way is to physically access the storage medium. Most Xiaomi cameras, including the popular 360 series and Outdoor, are equipped with a microSD card slot, which does not require complex network configuration and works even in the absence of Internet, if the device recorded in cyclic mode.
To get started, you need to remove the memory card from the device. Be careful: before extracting it, it is advisable to turn off the power to the camera through the application to avoid damaging the file system. Insert the drive into the card reader of your computer or laptop. The system recognizes it as a removable disk.
The folder structure on the map usually contains directories with dates or events. Video files often have a.mp4 or proprietary format extension that requires a special player. If you see files with a.dav extension or the like, you will need a conversion or specific software from the manufacturer.
⚠️ Attention: Frequent retrieval of the memory card can cause the slot contacts to wear out physically in the camera itself. Use this method only for a one-time unloading of a large archive, not for daily use.
When working with a file system, it is important to understand the difference between continuous recording and event recording. In the first case, the video is broken into chunks for 1 minute, in the second case, files can be longer. For easy viewing on a PC, you should use a file manager that supports preview.

Using the FTP protocol for a local network
More advanced users who want to automate the process should pay attention to the protocol. FTP. Some Xiaomi camera models allow you to set up sending pictures or videos to the camera. FTP-server when motion is detected, this requires you to raise the server on your computer or NAS-storage.
Setting up FTP-The server on the PC can be executed through standard Windows tools or third-party software like FileZilla Server. After creating a user and password, as well as specifying a folder to write, you need to copy. IP-In the Mi Home app, in the camera settings, find the notification section and select FTP.
Enter your server data: IP-Address, port (standard 21), login and password. Now, when the motion detector is triggered, the camera will independently transmit the video to your computer, which eliminates the need for manual downloads and saves space on the memory card.
⚠️ Attention: Protocol FTP Transmits data in an open form. Make sure your home Wi-Fi network is secure with strong encryption. WPA3 or WPA2, So that the attackers do not intercept the video stream.

Third-party management programmes IP-camera
If the built-in Mi Home functionality seems limited, you can use universal video surveillance software. Software like iSpy, ZoneMinder or ONVIF Device Manager can work with Xiaomi cameras if they support ONVIF or RTSP.
To start the work you will need to get RTSP-In newer firmware versions, this feature is often hidden or requires activation via modified servers (hack), which may not be secure. ONVIF, enable this option in the application and set a password to access the video stream.
In the client program, add a new camera by selecting the manufacturer Generic or "ONVIF". Enter. IP-port address (usually 554 for the RTSP), login and password. Once you're connected successfully, you'll have access to live stream and possibly an archive that can be uploaded to your PC's hard drive in a convenient format.
This approach makes your smart camera a complete security feature, with flexible detection, recording schedules and integration with other sensors, but stability depends on the quality of the protocol implementation in the particular camera model.
💡
For stable operation with RTSP/ONVIF set the camera up static. IP-address in the router settings, which will prevent communication from being interrupted if DHCP-The server will give the device a new address after restarting.
Comparison of data transmission methods
To make it easier for you to choose the best method, we have prepared a comparison table that will help you estimate the time and resources for each method depending on your tasks.
| Method | Speed. | Difficulty | Automation |
|---|---|---|---|
| Memory map | High (USB 3.0) | Low. | No. |
| FTP server | Medium (Wi-Fi) | Medium | Complete. |
| ONVIF / RTSP | Tall. | Tall. | Partial |
| The Mi Cloud Cloud | Low. | Low. | Yes (paid) |
As you can see from the table, physical access is faster, but requires manual intervention. Networking is better in convenience and automation, but depends on the quality of the wireless signal.
Network protocols are best suited for daily security use, and if you need to get evidence of an accident, the quickest thing to do is to just take out the memory card.
Solving problems with formats and codecs
A common problem when downloading video is that it cannot be played back with standard Windows tools. Xiaomi cameras can use specific codecs or containers to optimize the flow. If the file does not open, install the K-Lite Codec Pack first or use the VLC Media Player player.
Another common situation is no sound, which may be because the camera settings have turned off audio streaming, or your PC doesn't have drivers for AAC or G.711 format. Check the recording settings in the Mi Home app.
If the video twitches or has artifacts, the problem may be in broken sectors on the memory card or an unstable Wi-Fi connection when transmitted over the network, in which case it is recommended to format the card through the camera application, rather than through Windows, to restore the correct structure of the file system.
💡
Use it. VLC Media Player – it supports most rare codecs and streaming protocols out of the box, making it an indispensable tool for working with the Internet. IP-camera.
Organization of storage of archives on PC
After successfully uploading a video to a computer, the storage of the video takes up a lot of space, so it is recommended to use external hard drives or other hard drives. NAS-Create a clear folder structure: Year / Month / Date / Camera.
For automatic backup, you can use the standard Windows tool, File History, or third-party synchronization utilities, which will allow you to save copies of important records even in the event of a failure of the main drive of the computer.
Remember to periodically check the integrity of archives, files can get corrupted over time, and it's a shame to find out when you really need a video, and use checksum software if you're archiving critical data.
