Real-time video call: When someone rings the doorbell, our app will immediately send a call to your phone, allowing you to see the visitor on the monitor and talk to them. You won't miss any visitors even if you're not at home. If you can't answer the call, you can automatically record it for later review. With PIR motion detection, our video doorbell accurately detects people near your home and effectively captures human body contours. Radar detection ensures accurate visitor identification, allowing you to receive immediate notifications. In addition, the video doorbell records motion detection and plays it back to the monitor, enhancing your home security. The doorbell connects to a variety of 12V electronic door locks, such as electric, electromagnetic, and cathode ray tube locks. It can monitor the screen to unlock the door, use a smart card to unlock the door, and can also be unlocked at Remotely control via mobile app. Our video doorbell offers 1080P HD image quality and
