The situation when you need to set up a smart security camera, but you don't have a regular Wi-Fi router at hand, is quite common. This can be a garage, a remote warehouse, a summer cottage, or just a temporary need to move the camera into an area without wireless coverage. Many users mistakenly believe that the Xiaomi Mi Home ecosystem functions exclusively in conjunction with the home Internet, but this is not quite true.
The modern security devices from the Chinese tech giant have flexible communication protocols that allow you to organize the transmission of video stream in alternative ways. USB-A modem, create an access point on a smartphone, or even use a local Ethernet network if the camera model supports a wired connection. In this article, we will discuss in detail all possible scenarios that will help you launch the device even in the most difficult conditions.
It is important to understand that the absence of a classic Wi-Fi router does not mean abandoning remote browsing. Competent setting will allow you to receive notifications and see the picture in real time using only a smartphone and a smartphone. SIM-Next, we'll go into the technical details and look at the specific algorithms for different models of equipment.
Connection via the access point on the smartphone (AP Mode)
The most affordable method that doesn’t require buying additional hardware is to use your smartphone as a router. Most modern Xiaomi cameras, including the popular Mi Home Security Camera 360 and Mijia Outdoor Camera, support AP (Access Point) mode, in which case the phone gives off a Wi-Fi signal to which the camera connects and then broadcasts the Internet via a 4G/LTE mobile network.
To do this, you need to activate the Access Point feature in your Android or iOS device settings. Once you turn on the Internet Distribution mode, go to the Mi Home app and start adding a new device. When the camera detects your phone's network, it will try to connect to it. It is critical that the mobile Internet on your phone is active and has a stable signal, otherwise the video stream will be interrupted.
⚠️ Note: When using a smartphone as a router, the device’s battery will run out much faster than usual. It is recommended to keep the phone charging or use an external battery (Power Bank) during long-term camera operation.
There is a nuance with frequencies: some older Xiaomi camera models only work in the 2.4 GHz band. Make sure your hotspot on your phone is set to be compatible with devices, or use the "Maximum Compatibility" mode in the Wi-Fi distribution settings. If the phone gives away a 5 GHz network, the camera may simply not see it on the list of available ones.
Using a USB 4G/LTE modem for autonomous operation
If you need a stationary solution that will not depend on the battery charge of the phone, the best choice will be the best solution. USB 4G-This method turns your camera into a fully autonomous video surveillance station, and you'll need a modem from any carrier and an active modem. SIM-map with sufficient traffic.
The setup process is as follows: first the modem connects to the port. USB cameras (if the model supports power and data transmission via the USB, Some versions of the Xiaomi Outdoor Camera AW1) Or to an external power source next to the camera. USB-The port on the camera is powered only, so the modem connects to a separate Power Bank or adapter, and the camera connects to it through the creation of a local network if the camera has router functionality, which is rare.
A more common and reliable scenario for Xiaomi cameras is to use a modem that creates a Wi-Fi network itself. SIM-map 4G-You plug it into the power, and it starts to give away Wi-Fi. And then you set the camera up as if it were a normal home router: you pick the modem network and you type in the password:
| Type of device | Required SOFTWARE | Stability | Traffic consumption |
|---|---|---|---|
| Smartphone (AP Mode) | Built-in OS | Medium | High-pitched |
| USB 4G modem + router | Not required | Tall. | Medium. |
| Mi Wi-Fi Router (4G) | Mi Wi-Fi App | Very high. | Optimized |
| Portable MiFi | Not required | Tall. | Medium. |
Specialized Specialized Specialized Specialized 4G-Xiaomi routers such as Mi 4G These devices are designed specifically for working with SIM-And they have maps and Internet for smart homes. SIM-Maps and antennas to amplify the signal, making them an ideal partner for surveillance cameras in places without wired internet.
☑️ Preparation for autonomous work
Configuring a wired Ethernet connection (for models with a LAN-port)
Some advanced camera models, such as the Mi Home Security Camera PTZ Pro or enterprise versions, have a LAN port. This is the most reliable way to connect, eliminating problems with radio interference and wireless signal instability. If you have the ability to throw a cable or use existing wired infrastructure, this option is preferable.
You'll need an Ethernet cable to connect, and maybe a USB-LAN adapter if the camera doesn't have a built-in port but has OTG support. However, more often than not, the port is already integrated. You just plug a cable from an Internet source (a modem or other router connected to 4G) directly into the camera. The system automatically prioritizes the wired connection over the wireless one.
The advantage of this method is the minimum delay of video stream (ping) and the ability to transmit video in higher resolution without compression artifacts characteristic of Wi-Fi. In addition, a wired connection is almost impossible to drown out household radio interference, which is critical for security systems.
⚠️ Note: When using long cables (more than 50 meters) without signal amplifiers, the quality of data transmission may fall. Cat5e or Cat6 for stable speed.
If your Internet source is USB-A modem connected to a computer or a dedicated mini PC (e.g., based on a Raspberry Pi), you can set up port swipe to access the camera from anywhere in the world, even without Xiaomi’s cloud services, but it requires a deep knowledge of the network architecture.

Features of working with local storage without a network
It is important to distinguish between “connecting to the network to view” and “recording video.” Xiaomi cameras can record video to a microSD card even without an active Internet connection if they are powered. However, to set up cyclic recording or motion detection, an initial setup is still required.
If the internet is gone after setting up, the camera will continue writing to the memory card when motion is detected (if this feature has been activated previously), you can only view the archive by connecting to the camera locally (if the camera creates its own Wi-Fi network for direct connection) or physically removing the memory card. Some models allow you to connect to the camera directly via Wi-Fi, even if it does not have access to the WAN.
To do this, the Mi Home app often has a Connect to Camera or similar feature that uses a direct link. In this mode, you can view the archive and control the lens rotation from within the range of the camera module's Wi-Fi (usually up to 10-15 meters without obstacles).
A unique feature of Xiaomi’s protocol is that even without the Internet, the camera can save short videos 10-15 seconds long when the motion sensor is triggered, if the settings selected the event recording rather than continuous recording.
Solving Connection and Signal Stability Problems
When you run video surveillance without a standard Wi-Fi router, you may encounter a number of specific problems, most often due to incompatibility of communication channels or insufficient signal power. If the camera doesn't connect, try changing the Wi-Fi channel on your smartphone or modem. 2.4 GHz band congestion is a common cause of failures.
Another common problem is lack of nutrition. USB-Some modems or smartphones may not be able to produce the current needed to run the camera, especially if the IR light is on at night, in which case the camera will be constantly rebooted or shut down. Use external power for the camera, do not rely only on the port. USB power-intensive.
- 📶 Make sure that the Wi-Fi password does not contain any special characters that the camera may not handle correctly (it is better to use only letters and numbers).
- 🔋 Check the voltage at the output of the power adapter; most Xiaomi cameras require stable 5V and a current of at least 2A.
- 🔄 Try resetting the camera settings with the Reset button and pairing again, being in close proximity to the device.
If you use 4G-modem, make sure you're on SIM-card PIN-The cameras can't type pins, and the modem just won't get online, leaving the camera without internet. PIN-by inserting a SIM into the phone.
💡
To save mobile network traffic, set the camera’s “Move only” recording mode and reduce the quality of the video stream when viewed over the mobile network (for example, to 360p or 480p), leaving high resolution only for writing to the card.
