See who's at your door and answer from anywhere. Whether you're at home or on the other side of the world, the Smart Video Doorbell alerts you in real time on your smartphone when someone rings the doorbell. You then receive a video call on your smartphone, allowing you to see and talk to your visitor even if you're not at home. The Smart Video Doorbell also helps you secure your entrance. Thanks to intelligent person detection, you receive an immediate alert if someone is lurking near your door. The Smart Video Doorbell also alerts you if someone tries to disable it. This way, you can scare off intruders with the built-in speaker. The alerts are accurate and fully customizable: you can customize the notifications you want to receive and select the events you want to record. On the other hand, with the Alert-Zones feature, you can define up to 4 specific areas that you want to monitor.
