Xiaomi Outdoor Camera CW400 – Smart Outdoor Security Camera

The Xiaomi Outdoor Camera CW400 is designed for reliable outdoor monitoring with clear video quality and intelligent security features. It uses a 4MP image sensor with 2.5K resolution (2560 × 1440) to capture detailed footage, making it easier to recognize people, vehicles, and important activity around your property.

The camera features a large f/1.6 aperture lens and a 113° field of view, allowing it to capture brighter images while covering a wide monitoring area. This helps reduce blind spots and ensures better surveillance coverage.

With smart full-color night vision, the camera uses infrared lights and white LEDs to capture clear images even in low-light environments. When motion or a person is detected, the built-in lights can activate automatically to improve visibility and deter intruders.

The CW400 supports AI human detection, which helps reduce false alerts by identifying human movement more accurately than traditional motion detection systems. When activity is detected, the camera can trigger audio and visual warning alarms and send notifications directly to your smartphone.

For communication, the camera includes two-way voice support, allowing you to speak with visitors or warn suspicious individuals remotely through the Xiaomi Home app.

Designed for outdoor durability, the camera features IP66 dust and water resistance, allowing it to operate reliably in rain, dust, and harsh weather conditions.

Footage can be stored locally using a microSD card up to 256GB or through cloud storage options, ensuring your recordings remain secure and easily accessible.
