Xiaomi Outdoor Camera CW400
Model MJSXJ04HL weather-rated camera for yard or indoor monitoring: 4MP 2.5K video, color night imaging, pan-tilt coverage, two-way talk, and Mi Home control.
Sensor and stream
Four-megapixel sensor with F1.6 large-aperture lens and high-performance CMOS delivers 2.5K clarity—resolution 2560 × 1440 (horizontal detail above 2500 pixels). Field of view 113°. Encodes with H.265.
Low light and deterrence
Four-light intelligent full-color night vision preserves color in dim scenes; white fill light engages when a person is detected after dark. AI human-shape detection triggers recorded alarm clips and phone notifications. Acousto-optical warning plays an alarm tone and flashes high-frequency light on intrusion, with Mi Home push alerts.
Movement and network
Dual gimbal head sweeps 360° horizontally and 160° vertically. Dual high-gain antennas on Wi-Fi IEEE 802.11b/g/n 2.4GHz aim for stable links at distance.
Audio, timelapse, and security chip
Two-way voice uses a sensitive microphone and high-power speaker for outdoor conversations. Timelapse mode compresses long intervals into short clips. MJA1 Mijia security chip stores keys and certificates to protect communication and storage.
Storage, power, and environment
