The Xiaomi Solar Outdoor Camera BW400 Pro is a wireless security solution designed for external monitoring without the need for constant manual charging. It captures images in 2.5K resolution with a 4MP sensor and an f/1.6 aperture, providing clear visuals across a wide 132° diagonal field of view. To keep the device powered, an integrated solar panel converts roughly two hours of daily sunlight into energy for the 10000mAh battery, which can last up to 180 days on a single charge during normal use. Built to withstand the elements with an IP66 weather rating, the white cube-shaped camera features hardware-level HDR and dual night vision modes, using infrared for monochrome images or four white LEDs for color clarity. Intelligent software helps you distinguish between humans, animals, vehicles, and courier packages, while the built-in microphone and speaker allow for two-way audio communication within a range of 8 meters. Connectivity is managed through an included indoor base station that handles data processing to extend the camera's battery life. You can store your recordings on a MicroSD card inserted into this base station or use Xiaomi Cloud for a rolling 7-day history over three months, making it a practical choice for homeowners who want a low-maintenance way to keep an eye on their property.
