Xiaomi Outdoor Camera CW400 - 2.5K Outdoor Wi-Fi Security Camera

Ultra-Clear 2.5K Outdoor Watch With 360° Coverage

The Xiaomi Outdoor Camera CW400 records 2.5K (2560x1440) footage through a 4MP sensor and a large f/1.6 aperture lens, staying sharp and bright even in tricky lighting. A dual-gimbal design provides 360° horizontal and 160° vertical viewing angles, cutting down on blind spots around the property.

Four built-in lights enable smart full-color night vision, automatically switching on when a person is detected so nighttime footage stays in color rather than grainy black and white. AI human detection filters out false alarms from pets or moving branches, triggering recording and alerts only for relevant activity, while flashing lights and audible warnings actively deter intruders in real time.

A high-gain dual-antenna Wi-Fi design keeps the connection stable at range, and two-way voice communication with noise cancellation lets you speak to visitors from anywhere. An integrated MJA1 security chip protects data, storage covers microSD (up to 256GB) or cloud backup, and IP66 weather resistance supports ceiling, side, or pole mounting outdoors year-round.
