Does it need a power cable?

No. The camera runs wire-free on a 10000 mAh internal battery topped up by the integrated solar panel — one charge lasts up to ~180 days. When needed, recharge it over USB Type-C.

Does it support RTSP or ONVIF for an NVR or Home Assistant?

No. BW400 Pro has no official RTSP or ONVIF and is managed exclusively through the Xiaomi Home (Mi Home) app. Recordings are stored locally on microSD in the base station or in Xiaomi cloud. For voice, it works with Google Home and Alexa.

Where does the microSD card go and what size is supported?

The microSD card goes into the base station (not the camera) and supports up to 256 GB in FAT32 format. You can combine local storage with Xiaomi cloud.

Will it survive outdoors, in rain and dust?

Yes. The housing is IP66-rated — dust-tight and resistant to water jets, designed for outdoor wall or ceiling mounting.

Does it have optical zoom or pan-tilt (PTZ)?

No, it's a fixed-body camera without PTZ. It covers a wide 132° diagonal angle from one point, so choose the mounting spot to match the area you want to watch.

What's included in the set?

The set includes a BW400 Pro outdoor camera, a base station and a user manual. The camera films and records, while the station boosts the signal and holds the microSD card.

What it is, who it's for, what it does

About this product

A power cut, a fence with no socket, or a wall where you'd rather not run cables — BW400 Pro handles all of it. The set pairs a wire-free camera on a 10000 mAh battery with an integrated solar panel (up to ~180 days per charge) and a base station that boosts the signal and holds the microSD card (up to 256 GB). A 4 MP sensor with hardware HDR films in 2.5K (2560x1440), and the 132° field of view covers a yard or an entrance. Night vision runs two ways: infrared or full-colour with white-light LEDs. The AI chip tells apart people, animals and objects (a parcel, for example), while the mic and speaker enable two-way talk. The IP66 housing shrugs off dust and water jets. Everything is managed in the Xiaomi Home app, with Google Home and Alexa support. 24-month warranty.

Where it works

Use cases

Outdoor

Mounted at the gate with no socket nearby, the camera captures who comes and goes. AI person detection cuts false alerts, and two-way audio lets you talk to visitors or the courier.

Outdoor

At a country house or cabin where power often fails, up to ~180 days of battery autonomy plus the solar panel keep the camera running. Recordings save locally to microSD.

Outdoor

With AI object recognition, the camera notices parcels left at the door and animals passing by. 2.5K video and full-colour night vision give clear detail day and night.
