Xiaomi Smart Camera C400 2.5K Indoor Pan and Tilt with AI Detection
Editorial verdict
Grounded in published specifications
Summary verdict: Dual-band Wi-Fi and NAS recording are what separate this from the Rs3,000 tier. The 5 GHz radio matters because a 2.5K stream on a congested 2.4 GHz band in an apartment block is where most cheap cameras visibly stutter, and SMB recording to a NAS means footage lands somewhere you control rather than on a card that walks out with the camera.
Who should buy this
Anyone who wants 2K-class detail, on-device AI filtering, and footage stored on their own NAS.
Who should avoid this
Anyone wanting outdoor placement or Apple Home support -- neither is offered.
