Xiaomi Smart Doorbell 3

See Who's at the Door in Crisp 2K, Without Ever Charging It Often

The Xiaomi Smart Doorbell 3 captures visitors in 2K resolution (2304 x 1296) through a wide 180° diagonal field of view, so you see the whole porch, not just a narrow strip in front of the lens. Four 940nm infrared lights keep night footage clear without a distracting glow, and AI human shape recognition tells the difference between an actual visitor and a passing car or swaying tree, cutting down on pointless notifications.

A 5200mAh battery is the standout here, rated for roughly 4.8 months per charge, so it needs topping up only a handful of times a year via USB-C. Two-way audio with a built-in voice changer lets you talk to whoever's at the door while keeping your real voice private, and an auto-reply feature can handle common situations when you can't answer live.

Every clip is backed by 72 hours of free rolling cloud storage, no subscription or memory card required, and setup is entirely adhesive-based, no drilling into the door frame. The included chime plugs in separately and relays the doorbell over a dedicated RF connection, while the doorbell itself is protected against theft with a forced-removal alarm and 1-to-1 account pairing that renders a stolen unit useless.
