Compared to traditional doorbells, our doorbell comes with a 110° wide-angle camera, 2KFHD ultra-clear pixels, and infrared lights to provide a clearer and wider view outside the door. PIR human sensing sensors and AI humanoid recognition technology enhance the safety of your and your family's living environment. In addition, you can also make calls to people outside through the mobile app. In short, it is your ideal choice, allowing you to enjoy the convenience and security brought by smart devices fully.
