Xiaomi Smart Doorbell 4 Pro Dual Camera Edition Launched With 150-Degree Lenses

• Xiaomi's Smart Doorbell 4 Pro Dual Camera Edition is out in China at 499 yuan ($75), with an early-bird price of 439 yuan ($66).
• You get two lenses, a 5MP front-facing unit and a 2MP downward shooter, each covering more than 150 degrees diagonally, plus a 9,800mAh battery Xiaomi rates at roughly 172 days per charge in its lab tests.
• It ties into the Mi Home app, Xiaomi HyperConnect and XiaoAI voice control, and it takes microSD cards up to 256GB alongside 72 hours of free rolling cloud storage.

If you live in an Indian apartment where the delivery guy just leaves the box at your door, this one's built for that exact headache. A second camera that stares straight at the floor plus a battery you won't have to think about for months fixes the two things that make most doorbells annoying, missed parcels and constant charging. That's the whole pitch behind Xiaomi's Smart Doorbell 4 Pro Dual Camera Edition, and it does it without asking you to run a wire.

What's New

It's the extra lens that matters here. Xiaomi put a 5MP camera up front to catch faces and approach shots, and then tucked a 2MP camera underneath that points straight down at the welcome mat. So you actually see the package, not just the person who dropped it.

Both lenses stretch past 150 degrees diagonally, which is wide enough to cover a tight corridor. And for night time, Xiaomi went with 940nm infrared. No red glow. Your neighbours won't get that creepy blinking light in a shared hallway.

Key Features

Battery life is the other headline. Xiaomi claims about 172 days on a single charge from the 9,800mAh cell. That's based on its own lab run of 20 ten-second clips a day triggered by motion. Real use will vary, but it's a big number for a wire-free doorbell.

Motion sensing comes from two PIR sensors. They span 180 degrees horizontally and pick up movement out to five metres. You can dial sensitivity and clip length in the Mi Home app if it's pinging you too much.

On the software side you get AI that tags people, packages and pets, plus cloud facial recognition Xiaomi throws in free. There's also voice changer mode for calls, custom auto-replies, and a soft ambient light that pops on when someone walks up after dark.

Storage is flexible. Pop in a microSD up to 256GB or lean on the included 72 hours of rolling cloud storage. Xiaomi says everything's locked down with AES-128 encryption and a separate Mi Home security chip. And if someone tries to yank it off the wall, it screams, records, and pings your phone. Mounting's simple too, 3M pad or screws.

Smart Home Compatibility

This doorbell lives inside Xiaomi's world. HyperConnect pushes the live view to compatible Xiaomi TVs and smart displays, and XiaoAI lets you ask for battery status or pull up the feed hands-free. Everything else runs through the Mi Home app.

Who It's For

Renters and apartment owners who can't or won't wire a doorbell will get the most here. That floor-facing camera finally makes package checks useful. And if your home already runs on Xiaomi screens and Mi Home, HyperConnect and XiaoAI make it feel like it belongs. If you're outside that ecosystem, you're paying for tricks you won't use.
