Xiaomi is stepping up its smart home game with the launch of the Xiaomi Smart Camera 4, a compact 4K surveillance unit that packs serious intelligence, privacy features, and seamless HyperOS integration, all for just 249 yuan (around $34). Early buyers also get a 64GB microSD card in the box.

Xiaomi Smart Camera 4 Specifications
The camera features an 8-megapixel sensor with 3840 x 2160 resolution, paired with a bright f/1.6 aperture and a six-element all-glass lens setup. It supports HDR for better image balance in challenging lighting, ensuring clear, sharp footage whether you’re filming a sunlit living room or a dark hallway in the middle of the night.
It comes with Xiaomi’s in-house MJA1 AI chip, capable of 1 TOPS processing power, enabling on-device intelligence for human detection, pet tracking, baby crying alerts, and abnormal sound recognition, all without relying on cloud processing. This edge AI approach offers faster response times and enhanced privacy.
For low-light environments, it equips a 940nm infrared fill light that provides up to 10 meters of night vision without emitting visible red light. It also comes with a high-sensitivity sensor that extends color capture time even in dim conditions, delaying the switch to black and white.
Connectivity-wise, the Smart Camera 4 supports dual-band Wi-Fi 6 for faster, more stable streaming and includes two-way audio with built-in noise reduction, letting you communicate remotely with greater clarity, perfect for a quick chat with your pet or checking in at home from afar.
Design-wise, the device sports a clean, minimalist body mounted on a dual-motor gimbal that allows 360° horizontal and 109° vertical rotation. It lets you manually control its movement, set up automatic patrol routes, or define custom tracking zones to cover key areas like doors, cribs, or pet corners.
In terms of storage, it offers multiple options: up to 256GB via microSD card, NAS support, or Xiaomi’s encrypted cloud backup. All recordings use H.265 encoding to save space without compromising image quality.
Privacy is clearly a priority, the camera incorporates four layers of protection: local AI computing, encrypted data transmission, a physical lens cover, and a dedicated security chip.
As part of the HyperOS Connect ecosystem, the Smart Camera 4 integrates effortlessly with other Xiaomi smart devices. It triggers routines, works with voice commands via XiaoAi, and enables smart collaborations that go beyond simple surveillance.
