Smart locks and video doorbells are a key part of a smart home security system, providing an extra layer of protection and convenience. Smart locks allow remote door control via a smartphone or smart home platform, which is particularly useful for granting access to guests remotely, for example.

Video doorbells integrate with smart locks to provide a visual checkpoint at the front door of your home. Users can view real-time video from a camera attached to the doorbell and communicate with guests via audio. Many models also have motion detection and recording capabilities.

In general, these smart locks and video doorbells can be integrated with broader smart home systems such as Google Home or Amazon Alexa, enabling total home management through a single interface. They can also connect to other security systems, such as smart surveillance cameras and motion sensors, to create a comprehensive security network.

These smart devices bring both security and convenience to users, reducing concerns about home security and providing the ability to monitor and manage the home remotely.
