Xiaomi has released the Smart 4G Camera 3, a pan-tilt home security camera that gets online through built-in SIM cards. It is listed on Xiaomi Mall and Xiaomi Youpin in China. Crowdfunding opens on November 4, 2026. No international release has been announced.
Connectivity
Two SIM cards come pre-installed, one from China Telecom and one from China Unicom. The camera uses whichever has the stronger signal, so it can run in places with no router. Xiaomi includes free 4G data with no speed limit, no data cap and no top-up fees. The data only works inside the Mijia (Mi Home) app.
Video and night vision
The camera records at 2880 x 1620, which Xiaomi calls 3K, through a 5MP f/1.6 lens. A color sensor handles low light. The 940nm infrared light lets it shoot at night without a visible red glow.
Movement and AI detection
Dual motors pan the camera 360° and tilt it 109°. Five AI detection modes cover the home, children and pets, and alerts go straight to your phone. Two-way audio is included.
Storage and smart home features
AOR recording saves microSD space by deleting still images automatically. The camera links to other Mijia devices through Xiaomi HyperConnect and streams live to phones, tablets and Xiaomi TVs.
Price
During crowdfunding the camera costs 199 yuan (about US$28 to $29). The suggested retail price is 269 yuan (about US$38 to $40).
Not the Xiaomi Smart Camera 3 3K
The names are close, but the products are different. The Smart Camera 3 3K launched in China in January, uses dual-band Wi-Fi and records at 2960 x 1668.
What makes the below so obviously AI generated?
- Every section is the same size and shape, so it reads like a spec sheet cut into pieces.
- It has no point of view. Nothing says who this camera is for or where it falls short.
- Sentences are evenly paced, and several open with “The camera”.
- “Movement and AI detection” and “Storage and smart home features” are tidy bundles of unrelated features.
Final rewrite
Xiaomi Smart 4G Camera 3 Uses Built-In SIM Cards Instead of Wi-Fi
Xiaomi has released the Smart 4G Camera 3, a pan-tilt home security camera that connects through built-in SIM cards instead of Wi-Fi. It is listed on Xiaomi Mall and Xiaomi Youpin in China, and crowdfunding opens on November 4, 2026. Xiaomi hasn’t announced an international release.
4G instead of Wi-Fi
Two SIM cards come pre-installed, one from China Telecom and one from China Unicom. The camera picks whichever network has the stronger signal, so it can work in a garage, a shop or a holiday home with no router. Xiaomi bundles free 4G data with no speed limit, no cap and no top-up fees. The catch is that this data only works inside the Mijia (Mi Home) app, and the SIMs are tied to Chinese carriers, which is likely why there is no version for other markets.
Video quality and night vision
Video is 2880 x 1620, which Xiaomi markets as 3K, from a 5MP sensor behind an f/1.6 lens. For dark rooms there is a color low-light sensor and 940nm infrared, so night footage doesn’t come with the red glow most cheap cameras give off.
Pan, tilt and AI alerts
Two motors give a full 360° pan and a 109° tilt. The camera has five AI detection modes covering the home, children and pets, and it sends alerts directly to your phone. You can also talk through it with two-way audio.
Storage and smart home support
Recording goes to a microSD card. The AOR system saves space by deleting still images automatically, though Xiaomi hasn’t said which card sizes are supported. The camera works with other Mijia devices through Xiaomi HyperConnect and streams live to phones, tablets and Xiaomi TVs.

Don’t confuse it with the Smart Camera 3 3K
The names are close, but these are different products. The Xiaomi Smart Camera 3 3K came out in China in January, uses dual-band Wi-Fi (2.4GHz and 5GHz) and records at 2960 x 1668. The Smart 4G Camera 3 is the one with SIM cards.
