Xiaomi Smart Camera 4 Dual-Lens Edition

Xiaomi Smart Camera 4 Dual-Lens Edition is an indoor dual-camera security model designed to cover two views at the same time. The exact model code MJSXJ29CM is documented with two 5 MP imaging channels and 2960 × 1666 (3K-class) video.

One of the key advantages of the dual-lens layout is broader room coverage without requiring two separate cameras. The product also supports infrared night vision and local microSD storage, while dual-band Wi-Fi helps with network placement.

Retail documentation for MJSXJ29CM explicitly describes adding the camera to Mi Home and using the app for control. The model supports 2.4 GHz and 5 GHz Wi-Fi plus Bluetooth 5.4 for connectivity/setup.

The seller SKUs differ by plug/adapter only. Those passive adapter choices do not change the camera model. For a China-market unit, app-region availability can still matter, so confirm the region used by the exact retail unit before installation.

The camera is intended for indoor powered use. Network placement matters because live video, notifications and remote viewing depend on a stable Wi-Fi connection; the exact model supports both common 2.4 GHz and 5 GHz bands. Local microSD storage is optional and uses a separate card. Regional power-adapter choices in seller offers do not alter the camera’s imaging or wireless hardware.
