A doorbell camera is a smart security device that combines a doorbell with a built-in camera to monitor and record activity at the front door. It allows homeowners to see, hear, and communicate with visitors in real-time through a smartphone app, even when they are not home. Equipped with features like motion detection, night vision, and cloud or local video storage, a doorbell camera enhances security by capturing footage of deliveries, guests, and potential intruders. Many models integrate with smart home systems, offering added convenience and control. This device provides peace of mind by keeping the entrance of a home secure and easily accessible.
