Xiaomi MJSXJ27CM Smart Camera 4K Dual-band Wi-Fi 6 AI Tracking Night Vision Two-Way Audio: True 4K Ultra HD (8 MP) resolution
This Xiaomi Smart Camera 4 is designed for busy parents who need to keep an eye on their children while working from home or away. It goes beyond basic home security by offering a reliable way to connect with your family throughout the day.
With true 4K Ultra HD and AI-powered human motion detection, you get sharp, accurate alerts that focus on what matters. The two-way audio lets you hear a child's murmur from across the room and respond instantly. A simple "OK" gesture activates a call, so you can check in hands-free without interrupting your tasks.
Dual-band Wi-Fi 6 ensures smooth streaming even on crowded networks, while the 360-degree pan and tilt cover every corner. Night vision works without a red glow, and a physical lens shield protects your privacy. This indoor camera is Alexa compatible for easy voice control, giving you peace of mind with clear, actionable insights.
