Now you can easily keep track of who is on the other side of the door. The doorbell has a built-in camera with a sensor that detects motion and adjusts the light balance in the image, automatically switching from day to night, so you don't have to worry about blurry images. The doorbell can be wirelessly connected to your smartphone via a secure WiFi connection, so you can easily monitor your home when you are not at home. When someone stands in front of the doorbell, it will send a message to your smartphone.Specifications:Supports WiFi connection, Android/iOS applicationEasy to install and useNight visionCamera angle covers 166°Ultra-low power consumption, ultra-long standby timeWaterproofImage resolution: 720P/480NEncoding format: H.264Standby time: approx. 8 monthsAlarm response time: 3-55 secondsRecording method: manual, doorbell trigger, motion detectionTF card storage: maximum 32G TF card storage (not included)Material: ABSEnvironment: -10～50
