Features: Unlike traditional doorbells, this doorbell has no visible Wi-Fi signal, which makes it more secure and effectively prevents potential hacker attacks. Thanks to the advanced 2.4G private protocol and long-distance transmission, you can enjoy a stronger and more reliable signal protection with peace of mind. The convenience of our 4.3-inch IPS screen is clearly visible from any angle. Whether it is day or night, the built-in infrared night vision function allows you to see people nearby at any time, making you feel safe. .
