The Xiaomi Outdoor Camera CW400 delivers reliable, intelligent outdoor surveillance with 2.5K ultra-clear imaging, smart full-colour night vision, and a rugged IP66 weather-resistant design. Built to perform in harsh outdoor environments, it combines advanced AI detection, active defense features, and strong network stability for complete peace of mind.

Ultra-Clear 2.5K (4MP) Imaging

Equipped with a 4MP high-performance image sensor and an f/1.6 large-aperture lens, the CW400 captures brighter, sharper, and more detailed footage. With a resolution of 2560 × 1440, zoomed-in images remain crisp, making it easy to identify people and objects.

Smart Full-Colour Night Vision

The four-light intelligent night vision system automatically activates built-in white lights when a human is detected, delivering full-colour images even in low-light conditions. Infrared night vision is also supported, ensuring clear monitoring throughout the night.

Professional IP66 Weather Resistance

Designed specifically for outdoor use, the IP66 water-resistant and dustproof construction ensures stable performance in rain, dust, wind, and challenging weather conditions—ideal for entrances, compounds, parking areas, and perimeter security.

Dual-Gimbal Pan-Tilt Design for Full Coverage

The horizontal and vertical dual-gimbal system offers a 360° horizontal view and a 160° vertical view, delivering wide-angle coverage with fewer blind spots. Remotely adjust the camera position via the Xiaomi Home (Mi Home) App for flexible monitoring.

High-Gain Dual-Antenna Network

Built-in high-gain dual antennas provide enhanced Wi-Fi signal strength and long-distance transmission stability, ensuring smooth video streaming and reliable connectivity even in outdoor installations.

Featuring a high-sensitivity microphone and powerful speaker with smart noise cancellation, the CW400 enables clear two-way voice calls. Communicate easily with visitors, delivery personnel, or deter intruders—even in noisy outdoor environments.

AI Human Detection with Reduced False Alarms

The next-generation AI human detection algorithm accurately identifies people and filters out unnecessary alerts caused by animals or environmental movement. When a person is detected, the camera automatically records video and sends instant notifications to your smartphone.

Audible & Visual Warning for Active Defense

When intrusion is detected, the CW400 activates flashing lights and an audible alarm to deter potential intruders. Alarm notifications are sent simultaneously to the Xiaomi Home App for real-time awareness and response.
