What can a video doorbell assist you with?

A video doorbell can significantly enhance home security and convenience by fulfilling both functions mentioned in the options.

Firstly, it alerts your phone when someone approaches the door. This is important as it ensures that you are informed of any activity at your doorstep, even if you are not physically present. Most video doorbells come equipped with motion sensors that trigger notifications, allowing you to monitor your entrance at all times.

Secondly, it allows you to communicate with visitors from anywhere, even when you are not home. This feature is particularly useful for homeowners who want to screen visitors or deliver instructions to deliveries without having to be physically present at the door.

These two capabilities work together to increase security and enhance the user experience, which is why the choice that includes both functionalities is correct. Other options do not fully capture the comprehensive capabilities of a video doorbell, which combine real-time alerts with interactive communication.
