Xiaomi doorbell 4 PRO

Xiaomi Doorbell 4 Pro corresponds to the Xiaomi Smart Doorbell 4 Pro shown in the linked marketplace evidence. It is a connected video doorbell with dual lenses, a 5 MP main imaging channel, infrared night vision and a wide 150° view for seeing visitors and the area around the doorway.

The seller source also specifies 32 GB of built-in storage, allowing local event/video storage without relying only on a memory card. Two-way video-intercom use and phone notifications are handled through the Mi Home app.

The exact listing explicitly states Mi Home app support. For imported China-market smart doorbells, app-region availability can matter, so the Xiaomi Home/Mi Home account region should match the unit’s market version.

The source offers differ only by the included plug/adapter for the indoor chime/power accessory; that passive adapter choice does not change the doorbell model. The storefront therefore publishes the common camera/storage characteristics and avoids treating plug choice as a product-generation difference.

A video doorbell’s practical coverage depends on where it is mounted relative to the door and visitor approach. The 150° field of view and dual-lens layout are intended to capture more of that area than a narrow single-camera view. For imported units, confirm the Mi Home region and the supplied indoor power/chime accessories before installation; a travel adapter does not change firmware or regional app support.
