Smart doorbells were once a luxury item dominated by Ring, but Xiaomi’s entry has democratized doorbell cameras in China. The Xiaomi Smart Doorbell 3 (小米智能门铃3) brings 2K resolution, AI human detection, night vision, and free 3-day rolling cloud storage at just ¥299 (~$41 USD) on JD.com.

With 30,000+ reviews on JD.com and a 96% positive rating, it’s China’s best-selling smart doorbell. Let’s see how it compares to Ring and whether it deserves a spot at your front door.

Design and Build

The Doorbell 3 features Xiaomi’s clean white-and-black design. The camera lens sits at the top, flanked by IR LEDs for night vision. A large circular doorbell button dominates the lower half with a subtle LED ring that lights up when pressed.

Installation is peel-and-stick with industrial 3M adhesive or two screws (both included). The anti-theft screw at the bottom provides physical security — the doorbell can’t be removed without the special tool.

The included wireless chime plugs into any wall outlet. It pairs automatically with the doorbell and offers multiple ringtone options. Without it, visitors pressing the button would still trigger your phone notification, but the physical chime is essential for households where not everyone has the Mi Home app.

Performance

The 2K sensor (2048×1536) delivers crisp video. Faces at 2-3 meters are clearly identifiable. The 180° diagonal field of view captures the entire doorstep area — visitors can’t hide by standing to the side.

AI human detection is the standout feature. It differentiates humans from pets, cars, and swaying trees — dramatically reducing false alerts. When a person is detected, you get a push notification with a snapshot, and a 6-second video clip is saved to the cloud.

Night vision is effective up to 5 meters, producing clear black-and-white footage. The IR LEDs are invisible to the human eye, so they won’t bother neighbors.

Two-way audio has decent quality — visitors can hear you clearly, and you can hear them, though there’s a slight delay typical of network-connected devices.

What Chinese Users Say

Aggregated Ratings: 4.6/5 ★ (30,000+ reviews on JD.com, 96% positive)

“¥299 for peace of mind — confirm deliveries remotely, talk to couriers when away. 2K quality is clear, face recognition is accurate. Free cloud storage is the killer feature.”

“5 months on one charge — more durable than expected. Installation is easy, 3M adhesive holds firm. Only issue: battery drains faster in sub-zero winter temperatures.”

“Human detection is genuinely better than basic motion detection — no false alarms from cats or swaying leaves. Video quality is a noticeable upgrade from Doorbell 2.”

“Old apartment without doorbell wiring — this wireless doorbell is perfect. Put up a sticker telling couriers to press the button, and they all see it. Recommended for any old house without a doorbell.”

Pros & Cons

Pros:

• 2K resolution with 180° FOV — wide and detailed
• AI human detection reduces false alerts
• Free 3-day rolling cloud storage (no subscription)
• Wireless chime included
• 4-6 month battery life per charge
• Night vision up to 5m

Cons:

• No package detection (vs Ring)
• Battery drains faster in cold weather
• No wired option for continuous recording
• Cloud storage limited to 3 days
• Requires strong Wi-Fi at door location

vs Competitors

vs Ring Video Doorbell (¥999): Ring has package detection and a more polished app experience. But at 3x the price and requiring a subscription for cloud storage, Xiaomi is far better value for Chinese users.

vs Xiaomi Doorbell 2 (¥199): The Doorbell 2 is cheaper but limited to 1080p and weaker AI. The ¥100 premium for the Doorbell 3’s 2K camera and better detection is worth it.

FAQ

Q: Do I need existing doorbell wiring? A: No — the Doorbell 3 is battery-powered. Just stick it on your door frame. The chime plugs into any wall outlet.
