A video doorbell is a smart device that allows you to see and communicate with visitors at your front door using your smartphone or tablet. It has a built-in camera that captures video footage and a microphone that lets you talk to the person outside, even if you're not home. This feature enhances security by allowing you to monitor who is at your door in real-time. Many video doorbells also come with motion sensors that alert you when someone approaches your home. Some models even have night vision, ensuring you can see clearly at any time of day. With these devices, you can feel safer and more connected to your home.
