<p data-pm-slice="1 1 []">Smart doorbell cameras can provide additional visibility at the main entrance of a home. Depending on the model, they may offer live video, motion alerts, two-way communication, night vision, and visitor notifications through a compatible smartphone application. These features can help residents see who is at the door and review activity when they are away. Some models require wired power, while others use rechargeable batteries. Before installation, check Wi-Fi strength, power requirements, storage options, and compatibility with your existing doorbell. Positioning the camera carefully can improve visibility while respecting neighbors' privacy.
